The majority of fuel cells currently in use in data centers are solid oxide fuel cells (SOFCs), providing constant power. SOFCs can generate power through the conversion of fuels such as natural gas and biogas, into hydrogen, which is then reacted in the fuel cell to generate power. While using natural gas still results in carbon emissions, SOFCs are able to generate power with higher efficiency than combustion engines. SOFCs can also be fuelled directly with hydrogen, although this is not the norm due to hydrogen’s cost and availability.

Let’s just pause to emphasise this point: no amount of R&D, innovation or technology will allow us to remove CO2 from the atmosphere without spending at least 191 kWh per tonne of CO2.

It should be noted that the third normative approach considers the global need for electricity asoutlined by the International Energy Agency (IEA) for different scenarios and develops an interim1.5DS within which ICT should not expand its current share of electricity. This electricity budgetuses the IEA trajectories for a 2°C scenario (2DS) and a below 2°C scenario (B2DS) to derive a 1.5°Ctrajectory for world electricity usage through doubling the difference between them and subtractingit from the 2DS as described in [IEA ETP]. This is an interim approach as IEA has not yet establisheda 1.5DS. The budget is then used to determine the amount of electricity that could be used by thesector if keeping its share at the current level. As the IEA is planning to include a specific 1.5DS, thetrajectories will be reviewed when the new IEA scenarios are published.

The VIC system created maintains a list of available URLs or DNS entries for the service requiring computation, each of which live in a different datacenter in a different part of the world. When the service receives a request, it routes that request to the datacenter that best matches the required criteria

A TCP/IP based system was built to investigate the feasibility of a VIC as per Fig. 1. This considers routing Microsoft Azure workloads to datacenters around the world to best satisfy the required criteria. Three criteria were applied: (1) reduce load on a particular electricity grid at peak times, (2) follow green energy and low emissions energy around the world with computation, thus reducing curtailment of renewables and facilitating more renewable energy and (3) take advantage of variable electricity market prices.

Furthermore, many markets grant Capacity Payments to eligible generators and interconnectors for being available to follow dispatch instructions, irrespective of actual generation. VICs would also be eligible to receive such payments but they should be directly to the VICO rather than any users. This allows users to bid without the influence of capacity payments and rewards the datacenters providing the VIC.

Teleoperators are the world’s second-largest consumer of batteries. Elisa is also offering its Distributed Energy Storage solution to teleoperators in other countries so that they can improve the reliability of their own mobile networks and do their part in accelerating the green transition by investing in a distributed battery reserve and utilising it to provide balancing services in their electricity markets.

Net Zero Sales covers scope 1, 2 and 3 emissions on an intensity, full equity-share basisacross the value chain and seeks to reduce these:a. By 5% by 2025b. By 15-20% by 2030c. To net-zero by 2050

“A reporting organization should not purchase renewable electricity and simply apply it to scope 3 emissions without involvement from its supplier or customer.” Renewable Electricity Procurement on Behalf of Others: A Corporate Reporting Guide (page 4), EPA, 2022.

Microsoft’s 2021 Environmental Sustainability Report includes 11 of the 15 scope 3 categories (page 19), while Google reports business travel and employee commuting as one total and “other” scope 3 emissions in a second total (page 11). Apple(page 84) and Amazon (page 97) report lifecycle emissions from customer trips to physical stores under scope 3 which are not categories prescribed by the GHG

Certigy, a European EAC registry, has enabled hourly certification across many EU countries

Apple, which has a relatively long history of reporting its scope 3 emissions, states in its 2022 Environmental Progress Report that it is actively evolving its scope 3 accounting methodology. “In fiscal year 2017, we started calculating scope 3 emissions not listed above. In fiscal year 2021, these include electricity transmission and distribution losses [...] and life cycle emissions associated with renewable energy. We have not accounted for emissions resulting from employees working from home [...] we are still evolving our methodology.“ Environmental Progress Report (page 84), Apple, 2022

This also explains why, even though Norway’s grid-levelemissions factor is 10 kg CO2/MWh17 (98% carbon-free), the residual

emissions factor is 402 kg CO 2/MWh (7.4% renewable), reflectingthat most EACs produced within the Norwegian grid are claimedand retired outside of the country.

Data demonstrate that many companies do indeed pursue thispractice. For example, Norway was responsible for 43% of allguarantees of origin (GOs) exports in Europe in 2022, many ofwhich were purchased by companies whose operations have noconnection to the Norwegian grid on which these EACs wereproduced.

Wind and solar are, of course, intermittent, but battery costs too are plummeting, to the extent that they often underbid so-called peaking plants burning natural gas

This article in effect requires local authorities to only use data centres that a fully compliant with the requirements of the specified directives.

Article 33 Delegated Acts 3. The Commission is empowered to adopt delegated acts in accordance with Article 34 to supplement this Directive by establishing, after having consulted the relevant stakeholders, a common Union scheme for rating the sustainability of data centres located in its territory. The Commission shall adopt the first such delegated act by 31 December 2023. The common Union scheme shall establish the definition of data centre sustainability indicators and shall set out the key performance indicators and the methodology to measure them.

5. By 15 May 2025, the Commission shall assess the available data on the energy efficiency of data centres submitted to it pursuant to paragraphs 1 and 3 and shall submit a report to the European Parliament and to the Council, accompanied, where appropriate, by legislative proposals containing further measures to improve energy efficiency, including establishing minimum performance standards and an assessment on the feasibility of transition towards a net-zero emission data centres sector, in close consultation with the relevant stakeholders

. The Commission shall establish a European database on data centres that includes information communicated by the obligated data centres in accordance with paragraph 1. The European database shall be publicly available on an aggregated level.

We think that the threshold for reporting being 500kw is too low, as it will not pick up aggregated edge sites (organisations that have multiple facilties that individually are below the threshold but aggregated would be considerably higher), Mobile Phone basestation sites and Points of Presence (PoPs)

This links back to the lower limit for reporting of 500kw, clearly the EC see no reason to collect data from 'distributed compute' such as individual server rooms (at this time)

This is very interesting, we've seen some national government initatives in various countries relating to the collection of data centre energy data, in the UK we have the Climate Change Agreement for Data Centres which started in 2014 and according to the latest figures (4th Period) indicated that total UK energy use of the period for commercial data centres (colocation sites) was 12TWh. Back to the EED and the very interesting thing is the mention of 'interventions' will this mean the imposition of fines for poor energy performance?

This introduces the requirement for a data centre register and the rating of data centres for sustainabilty, this could become an utter bag of worms, as sustainability is closely linked to the amount of renewable energy systems on an individual country grid, the 'grid mix' and could favour those countries and data centres that are directly linked to low carbon energy sources (Norway, Sweden, Finland (Hydro), France (Nuclear), Spain (Solar/Wind) & Denmark (Wind).

It’s pretty simple: don’t let carbon removal excuse ongoing or worsening emissions. That means no deal with fossil fuel majors. And if you really must sell carbon credits, here’s my idea: they can only apply to the earliest emissions first. Once we’ve dealt with the ~2,500 ish human-added CO2 gigatonnes in the atmosphere, THEN you can apply credits to new emissions. We go from oldest to newest, not from newest to oldest.

This approach results in our Scope 2 market-based emissions being greater than zero, per the Greenhouse Gas Protocol Scope 2 Guidance, despite us achieving our 100% renewable energy match globally.

Electricity purchased from renewable sources (%) is calculated on a calendar-year basis, dividing the volume of renewable electricity (in megawatt-hours) procured for our global operations (i.e., renewable energy procured through our PPA contracts, on-site renewable energy generation, and renewable energy in the electric grids where our facilities are located) by the total volume of electricity consumed by our global operations. This metric includes all renewable energy purchased, regardless of the market in which the renewable energy was consumed

Reverse proxy implementation in nginx includes in-band (or passive) server health checks. If the response from a particular server fails with an error, nginx will mark this server as failed, and will try to avoid selecting this server for subsequent inbound requests for a while.

Without having to take any risk themselves, they collect increasing profits that are indirectly paid for almost entirely by the European taxpayer. At the current interest rates, this costs the European treasuries 135 billion annually. Dutch banks receive about 11 billion of that sum, of which only 8 billion – 5.8 per cent of total payments – is being borne by Dutch taxpayers. The rest is being paid for by the taxpayers of other European countries, because the interest payments of all central banks within the Eurosystem are mutually settled via a fixed capital key.

WattCarbon decarbonization projects are measured using official government grid data1, site level metered energy data, and open source avoided energy use methodologies2, which provides the highest degree of transparency and integrity for every project on our marketplace.

Players confront challenges mirroring those in the real world: they extinguish forest fires, obstruct illegal logging, replant native trees and clean up rivers.

It proved to be so effective that criminalisation spread across Latin America and is now deployed globally as part of a playbook of tactics to divide communities, and detract attention away from legitimate debate and protests about environmental and climate harms.

Experts say that what happened here helped to establish criminalisation as a go-to tool for polluting industries and governments seeking to discredit and silence activists. Guatemala was a textbook example of a draconian crackdown, becoming a laboratory of sorts, with arbitrary charges used against countless community leaders opposing environmentally destructive projects.

As plaintiffs’ counsel Nate Bellinger, senior staff attorney at Our Children’s Trust, stated in his closing: “It’s worth remembering other times in our nation’s history when the political process didn’t work to protect people’s basic human rights. Segregation, women’s rights, equal and adequate public schooling, marriage—time and time again, the political will of powerful majorities was struck down by courts, based on the compelling evidence before them, courageously correcting the injustices thrust on the people. Today, the injustice squarely before this Court is the proven harms of these young people wrought by climate change caused by a fossil fuel-based energy system imposed and perpetuated through the law.”

But as climate policy analyst Peter Erickson explained during his expert testimony on the plaintiffs’ side, Montana’s total annual CO2 emissions – 166 million tons (based on 2019 data) – are on par with annual emissions of entire countries like the Netherlands and Pakistan. “To call [Montana’s] emissions miniscule is then to call the emissions of over 100 countries of the world miniscule,” Erickson said. “Montana’s emissions matter”, he emphasized.

You may have heard of the 3-2-1 backup strategy. It means having at least three copies of your data, two local (on-site) but on different media (read: devices), and at least one copy off-site.

The value of provenance information  Adding provenance information to media to combat misinformation is not a new idea, and early research seems to show that it could be promising: one project from a master’s student at the University of Oxford, for example, found evidence that users were less susceptible to misinformation when they had access to provenance information about content.

They also worked their media mogul pals, like Mike Bloomberg, who added their names to the "Friends of Mike" list that Bloomberg reporters were required to consult before writing negative coverage

Full text seach is a way to avoid these two issues. With SQLite, you enable full text search by creating what is called a "virtual table" using one of the FTS engines included with SQLite: FTS4 or FTS5. FTS5 support is the most recent and has more advanced searching features, including ranking and highlighting of results and is what is described here.

Let’s dissect this piece of Mojo code. First, you'll notice that we have new variable declarations let and var which may look odd at first glance since this is not familiar Python syntax. Mojo offers optional (except in some cases, more on that later) variable declarations to declare variables as immutable with let (i.e. cannot be modified after creation) or mutable with var (i.e. can be modified).

In this example we have run sysbench --cpu-max-prime=25000 --threads=1 --time=10 --test=cpu --events=0 --rate=0 and put a CPU % limiting on the process and increased that in 10% increments. The blue curve has been done with the schedutil CPU frequency govenor which dynamically scales the CPU frequency. And the red curve has been done with the performance scaling govenor which scales the CPU frequency to a maximum as soon as even a minimum amount of load happens on a core.

Suprisingly we see that on an unloaded system the energy actually increases! The assumption made here is that the cost per instruction goes down. This is an effect that can also be seen in SPECPower benchmarks where the sweet-spot for a system is typically somewhere around the higher third quarter of the peak performance.

The legislative proposal risks rendering obsolete such ambitious and holistic industry-led initiatives that provide a tool for more informed consumer decisions, encourage improvements by manufacturers and demonstrate European leadership on sustainability questions. The Regulation should instead enable such schemes (which go beyond environmental claims, and consider aspects like durability, recyclability, etc.) to continue being used.

These companies start with people who have the least agency and social power and wreck their lives, then work their way up the privilege gradient, coming for everyone else. It's called the "shitty technology adoption curve":

Funneled into the colocation space, this rising demand has almost completely saturated Tier I data center markets like Ashburn, Dallas, and Silicon Valley. As a result, hyperscale workloads are driving growth in Tier II and Tier III markets, occupying existing capacity and spurring new developments.

New technologies can change who holds power and threaten how things work. Decisions about technology become wrapped up in fights to preserve or change political culture. When thinking about technological changes, we can’t just approach it as a project of modernisation – we need to have a view on the culture we want to create.

As it stands, Intel will walk away with the lion's share of the funding for its Magdeburg megafab, where it plans to produce angstrom-class parts beginning in 2027. After months of negotiations over rising operating and materials costs associated with building in the region – the facility is now expected to cost €30 billion to complete – the x86 titan received commitments from German officials in June for €10 billion in support.

Storage –Increasing solar penetration causes the number of high-load hours (within 5% of peak) to decline from seven hours in the Base scenario to just two hours in the Accelerated scenario.

Decarbonize Alibaba (Scopes 1 and 2): By 2030, we will achieve carbon neutrality in our own operations.Green the value chain (Scope 3): By 2030, we will collaborate with our upstream and downstream value chain partners to cut emission intensity by 50% from the base year of 2020. Alibaba Cloud will achieve Scope 3 carbon neutrality during the same period.Enable a low-carbon circular digital ecosystem (Scope 3+): Beyond our own operations and direct value chains, we pledge to leverage our digital platforms to encourage even broader participation by stakeholders that can be reached by our efforts. By 2035, we will facilitate 1.5 gigatons of GHG emission reduction over 15 years across Alibaba's digital ecosystem.

In 2021, Alibaba set ambitious targets of achieving carbon neutrality in our own operations and halving the energy intensity across our value chain by 2030 and driving emission reduction of 1.5 gigatons over 15 years in our platform ecosystem

Not that an E2E rule precludes algorithmic feeds: remember, E2E is the idea that you see what you ask to see. If a user opts into a feed that promotes content that they haven't subscribed to at the expense of the things they explicitly asked to see, that's their choice. But it's not a choice that social media services reliably offer, which is how they are able to extract ransom payments from publishers.

This is nonsense: when users are given the choice to block surveillance, they overwhelmingly do. Apple's iOS devices offer users a one-click opt-out from app-based surveillance. Ninety-six percent of iOS users have opted out (presumably the other four percent were confused — or on Meta's payroll).

First and foremost, where will a largely desert country source the water for electrolysis? Secondly, will Namibia export only hydrogen, ammonia, or some of the industrial products made with the green inputs? It would be advantageous for Namibia to develop a heavy-chemicals and iron-smelting industry. But from Germany’s point of view, that might well defeat the object, which is precisely to provide affordable green energy with which to keep industrial jobs in Europe.

The Lyubchyks estimate that the levelised cost of energy – the average net present cost of electricity generation for a generator over its lifetime – from these devices will indeed be high at first, but by moving into mass production, they hope to lower it significantly, ultimately making this hygroelectric power competitive with solar and wind. For that to work, though, they’ll need investment, access to raw materials and the equipment to process them.

They’ve come a long way since then, with Catcher and related projects receiving nearly €5.5m (£4.7m) in funding from the European Innovation Council. The result is a thin grey disc measuring 4cm (1.5in) across. According to the Lyubchyks, one of these devices can generate a relatively modest 1.5 volts and 10 milliamps. However, 20,000 of them stacked into a washing machine-sized cube, they say, could generate 10 kilowatt hours of energy a day – roughly the consumption of an average UK household. Even more impressive: they plan to have a prototype ready for demonstration in 2024.

The arrangement will see Contact provide Microsoft with all the renewable energy attributes generated by Contact’s new 51.4MW Te Huka Unit 3 geothermal power station.

Tonne-for-tonne offsetting has historically relied upon the cheapest possible carbon credits that do little to benefit the climate and represent no real pollution cost for companies. Polluters should move to money-for-tonne contributions instead, based on an internal carbon price (WWF recommends $50-250), which would encourage the purchase of higher quality carbon credits with co-benefits. The internal carbon price in turn could be proportional to companies’ revenues or profits. 

Finally, the Act still requires facilities to use 50 percent renewable energy by 2024, and 100 percent by 2027. An amendment is expected to clarify that this demand can be met by using certificates brought from Nordic suppliers; instead of relying on German green power.

In Neubauer, for example, legal advocate Roda Verheyen has been part of other strategic climate cases, such as the high-profile case of a Peruvian homeowner, Lluiya, suing RWE for compensation for climate harms

Dr Lisa van Aardenne, the chief scientist of the University of Cape Town’s climate system analysis group, discussed the use and utility of thermal stress indices. She pointed out that, by the definitions of the universal thermal climate index, much of Africa is under heat stress most days of the year.  Van Aardenne noted that these indices have been developed from a European perspective and do not align with the reality on the ground in Africa. She added: “I’m very concerned that these indices are not fit for purpose here.”

Prof Kris Ebi from the University of Washington started off the third day of the conference with a presentation on heatwaves and early action plans. She pointed to the 2021 Pacific north-west “heat dome” event, which resulted in around 800 excess deaths and was later found to be a 1-in-10,000 year event. The rarity of that event means, in effect, “these people died because of climate change,” Ebi said. She added: “Every heat-related death is preventable.”

Dr Sokhna Thiam, from the African Population and Health Research Center in Nairobi, Kenya, added that water-borne enteric diseases are among the “primary expected health impacts” of climate change.

Together, the plants will enable more than 120 gigawatt-hours of U.S. battery production annually and displace more than 455 million gallons of gasoline per year, LPO reported.

Calhoon of ClimateWells acknowledges the worry that oil operators will simply drill new wells in other places, canceling out any emissions reduction benefit from plugging older ones. In the carbon credit market, this notion is called “leakage,” meaning that the emissions are not prevented but essentially moved.

California Legislation Would Force Corporate Polluters to Come Clean

We don’t provide banking services to or invest in organisations that use excessive power to systemically promote public behaviour that is harmful to individuals, groups or to the whole of society in order to maximise their own profits. This may include, for example, arms manufacturers and tobacco companies.

For now, we haven’t included emissions relating to loans and investments in our Scope 3 carbon footprint breakdown as these are worked out separately with the Partnership for Carbon Accounting Financials (PCAF). We were the first UK digital bank to join PCAF, which asks members to calculate emissions from loans and investments by following industry best practice

As a policy, end-to-end has a lot going for it. First, it is easy to administer. If you want to find out if a company is reliably delivering posts from willing senders to willing receivers, you can easily verify it by creating accounts and performing experiments. Compare this to more complicated policies, like "platforms must not permit harassment on their services." To administer that policy, you need to agree on a definition of harassment, agree on whether a specific user's conduct rises to the level of harassment, then investigate whether the platform took reasonable steps to prevent it.

It adds that there is “no shortage of physical capacity”, with Chinese coal plants running an average of 52% of hours in the year (4,600 out of 8,760 hours). CREA continues: “Thus, simply adding more coal capacity across the whole of China may not fundamentally address the power shortages in China.”

The country is also slowly shifting from an “equal share” dispatch system to an “economic dispatch”, which is more responsive to consumer demand. (CREA notes that the “equal share” system is another barrier to greater flexibility.)

“Given the rapid growth of clean energy and expected slower electricity demand growth, the massive additions of coal-fired capacity don’t necessarily mean that China’s coal use or CO2 emissions from the power sector will increase.” 

China’s power market remains primarily coal-fueled. Coal made up 61% of electricity generation in 2022, while wind and solar power – despite making up a growing proportion of power capacity – accounted for only 14% of generation.

The average price for a solar panel delivered in the United States was 38 cents per watt as of June 7, which is double the global average, according to BloombergNEF and PV InfoLink. The U.S. price has been about the same, going up or down just a penny or two, since last fall.

This move was heavily pushed for by the three-party coalition’s smallest member, the Free Democrats who are in charge of the transport ministry. This means if a target in one sector such as industry, transport, or buildings is missed, another sector can compensate for it.

To that end, we’re excited to announce the launch of the VMware Zero Carbon Committed cloud partner initiative. We envision catalyzing and accelerating the transition to zero carbon clouds through VMware Cloud Partner data centers powered by renewable energy sources by 2030. This initiative is a collaboration with our VMware Cloud Verified providers that operate infrastructure-, energy- and carbon-efficient data centers based on VMware software-defined data center (SDDC) technologies and have commitments to using renewable energy power. Exemplifying VMware’s ongoing commitment to product sustainability innovation, this initiative aims to: Catalyze the transition to a zero carbon internet through our partnerships with public cloud providers. Help customers reach their sustainability and decarbonization goals by connecting them with cloud providers that have aligned goals. Accelerate sustainable computing with VMware’s SDDC technology.

Without public access to the emissions data SBTi sees, its climate targets are “effectively inscrutable,” she and other scientists told the organization in October

Under SBTi’s net-zero plans, companies can counterbalance up to 10% their emissions with “permanent removal” of carbon dioxide from the atmosphere. These efforts, it expects, will have negated 20 to 40 billion tons of emissions by 2050.

SBTi has recently stopped approving plans for this looser target

We can solve this problem by defining separate types for different kinds of IDs with a “NewType”:

The first successful trust was Rockefeller's Standard Oil, which amassed a 90% share of all US oil. Other "capitalists" got in on the game, forming the Cotton Seed Oil Trust (75% market share), the Sugar Trust (85%). Then came the Whiskey Trust and the Beef Trust. America was becoming a planned economy, run by a handful of unelected "industrialists" with lifetime appointments and the power to choose their successors.

The authors then divided that figure by three, proposing that the total costs should be shared equally by the governments that allowed companies to pollute, the consumers who bought fossil fuels and the corporations that produced them.

The Inflation Reduction Act’s first-ever methane fee for large emitters will also start in 2024 at $900 per ton of methane and increase to $1,500 per ton by 2026.

There are snakes, and the turnover is horrible. People are like, ​‘The heck with this. I’ll go work at an Amazon distribution center.’

OpenCost and Kubecost are helpful for monitoring, allocating, and optimizing Kubernetes costs granularly. Both monitor Kubernetes costs in K8s environments, but neither goes beyond that. For costs outside of Kubernetes, or to consolidate costs of containerized and non-containerized resources in one place, you’ll likely need another service, adding complexity and expense. Alternatively, you can use a Kubernetes cost optimization platform that does both. CloudZero provides granular Kubernetes cost analysis across major cloud providers, including single-cloud, multi-cloud, and hybrid clouds — down to individual customers (unit economics).

With Kubecost, you can estimate costs using a model calculation or connect your hypervisor to get exact figures.

The Guardian recently revealed that Turkmenistan was the worst in the world for methane “super emitting” leaks. Separate research suggests a switch from the flaring of methane to venting may be behind some of these vast outpourings.Flaring is used to burn unwanted gas, putting CO2 into the atmosphere, but is easy to detect and has been increasingly frowned upon in recent years. Venting simply releases the invisible methane into the air unburned, which, until recent developments in satellite technology, had been hard to detect. Methane traps 80 times more heat than CO2 over 20 years, making venting far worse for the climate.

With CPU TDPs skyrocketing, these typical datacenter racks are now more power-constrained than space constrained. Stacking a rack full of high-density blade servers with high-power Xeons would blow out this power budget many times over, requiring specialized datacenter infrastructure with higher cooling capabilities. We also see this with Nvidia’s AI servers. Their DGX SuperPOD design is not able to fully populate each server rack due to the huge power consumption. Nvidia AI servers are often as much as 5U to 6U, with the A100 DGX servers being ~6.5 kW and the H100 10.2kW.

Ampere also places a large emphasis on clock speed consistency. Intel and AMD CPUs vary their core clock speed significantly based on how many cores or threads are in use and what type of code is being executed. This helps their CPUs maximize performance within a given power and thermal budget, which is a huge advantage in many workloads.

They believe the future of computing will rely heavily on microservices, containerization, and serverless execution models. These concepts are generally about scaling performance out via a large amount small jobs and processes and not overly focusing on single-threaded CPU performance. Both AMD and Intel are releasing CPUs with similar strategies over the next year

The continued funding of fossil fuel projects remains a grey area

Simultaneously, another evolution is also taking place at the World Bank. From July, all projects that go to the board for funding will have to demonstrate that they are in line with the goals of the Paris Agreement.

One example algorithm aims at switching on/off Pico-BSs in a heterogeneous network (see Fig. 1) [5]. There is one Macro-BSs that is always active and provides coverage in the area, while several Pico-BSs can be intelligently activated/deactivated depending on the current traffic volume. E.g., one could imagine that Pico-BSs are needed during the daytime in the city center where a lot of people work, but during the nighttime, some of them can be put into sleep mode as most people came back to their homes in the suburbs. The process is driven by the so-called Reinforcement Learning (RL), i.e., learning through interaction. The aim of the agent is to learn which set of active Pico-BSs would provide the best EE under a given spatial distribution of users.

Another key argument for community energy is that involving ordinary people in energy generation and distribution boosts local acceptance for renewables. Not-in-my-backyard protesters have slowed the expansion of new wind farms across Europe in recent years. But where the wind farms are "owned by local community stakeholders, such as farmers, landowners, individuals, [and] municipalities," they "often enjoy higher levels of trust than commercial developers, which are usually not embedded locally," concludes a 2020 study by the Cicero Center for International Climate Research in Norway.

Nevertheless, proponents of community renewables argue that they are integral to the goal of achieving carbon neutrality and should continue to receive state support. They point out that community renewables boost local economic activity through investment, jobs and tax revenue. One German study showed that a seven-turbine community wind park of 21 megawatts generated $71 million in regional income over a 20-year operating period, while the same-sized park in the hands of commercial developers produced only $8.6 million for the local economy. The difference lay in the profit, tax revenue and job creation that stayed in local hands.

In Denmark, Europe’s other community energy powerhouse, community initiatives took off in the early 1980s. Danish communities invested in onshore wind turbines and district heating systems. By 2016, 67 percent of onshore wind energy in Denmark was generated by citizen-owned parks. This production, together with bioenergy and offshore wind generation, grew the country’s share of clean electricity to more than 50 percent of consumption by 2019.

In Germany, citizen energy stretches back to the 1980s and '90s when environmentally minded groups began striking out into renewable energy. Communal energy projects in Germany took off dramatically when the EU broke up the private-sector energy system monopoly in 1998, and the German government set up a price-support scheme that favored renewables in 2000. In the first decades of Germany’s Energiewende, or energy transition, grassroots energy projects and private individuals produced the bulk of clean energy, while the utilities held out, believing conventional energy would prevail, as it always had.

Nvidia is the largest customer of CoWoS for their A100 and H100 class datacenter AI GPUs. Google, through Broadcom, is the 2nd largest customer for TPUv4 and TPUv5. AMD also utilizes CoWoS in some capacity, but their volume in 2023 is relatively small. Lastly, Amazon’s Trainium through AlChip, as well as Microsoft’s new AI chips, also use CoWoS.The demands of AI training on memory performance are pushing designs to use High Bandwidth Memory (HBM), which has to be connected using advanced packaging technologies such as CoWoS. Any one of these companies and, more likely all of them are increasing spending heavily and require more CoWoS capacity. To be clear, Amazon’s Tranium, despite big orders through Alchip, isn’t that great, and Microsoft’s 1st gen AI chip won’t be able to replace Nvidia either.

TSMC also talked about a fab cancellation and how an expansion is now no longer financially feasible. We will be sharing some of our data about TSMC’s utilization rates and how TSMC’s pricing is coming down. We dive deep into TSMC’s 3nm and 5nm ramps as there are some quite heroic assumptions that TSMC is making regarding those in the back half of the year.

Qualifying EVs also can’t contain inputs from ​“foreign entities of concern,” a concept that the Treasury Department has yet to explicitly define, but which is expected to include many Chinese firms. (If you haven’t heard, China dominates the EV supply chain.)

This is a very weird imaginative failure. America operated public banks. It had broken up too big to fail banks. These weren't the deeds of a fallen civilization whose techniques were lost to the mists of time. There are literally people alive today who were around when America operated nationwide public banks – a practice that only ended in 1966!

Wooden towers are promising when it comes to material costs and availability; the company uses Scandinavian spruce from sustainably managed forests, for which regrowth exceeds logging. According to its calculations, a typical turbine tower requires between 300 and 1,200 cubic meters of wood, equivalent to 1.5 to 5 minutes of growth in Swedish forests.

Alphabet Inc. calculates the total electricity procured from renewable sources by totaling the amount ofrenewable electricity generation from the grids Alphabet Inc. uses, the amount of on-site renewableenergy generation and the amount sourced through contractual instruments (PPAs) globally

Unlike the Nazis, whose plan involved liquefying coal, the current German government is promoting a cleaner technique that entails extracting hydrogen from water and combining it with carbon dioxide to create fuel. At the heart of both methods is what’s known as Fischer-Tropsch synthesis, a process developed in the 1920s by two German chemists, Franz Fischer and Hans Tropsch.

At 0.5gCO2e per person per day, the absolute reduction potentialis negligible and highlights the need for more research to support thedecarbonisation of digital media. While video streaming constitutesthe majority of data traffic in the Internet, and the energy consump-tion of user devices is substantial (in particular TVs), an attributionalapproach overestimates the potential reductions of interventions

This is why I believe it’s much more useful, and less confusing, to just talk about Layer 1 government-issued money and Layer 2 bank-issued chips.

A country’s residual mix represents the shares of electricity generation attributes available for disclosure, after the use of explicit tracking systems, such as GO, havebeen accounted for.Without a residual mix, renewable electricity sold with GOs would be double counted because the same electricity would be disclosed to consumers buying “regular” electricity

Reporting via the CSRD will incorporate the increasing demand for digitization. Companies will be required to prepare their reporting in XHTML format in accordance with the European Single Electronic Format Regulation. They are also required to tag sustainability information within the report according to a digital categorization system, which should be developed with the ESRS.

The CSRD will also mandate the reporting of Scope 3 emissions from across the full value chain. This arises from guidance set out by the European Financial Reporting Advisory Group’s (EFRAG) draft European Sustainability Reporting Standards (ESRS) - specifically “Disclosure Requirement E1-9 – Scope 3 greenhouse gas (GHG) emissions” which states that “The undertaking shall disclose its gross indirect Scope 3 GHG emissions in metric tons of CO2 equivalent.”

Google, with their Apollo project, has developed a non-blocking 136x136 optical circuit switch that is both forward and backward-compatible with any bandwidth or wavelength Google uses or will use in its data centers. This switch, according to Google, only uses 108 watts of power consumption. Compared to a standard 136 port EPS switch, which would be in the 3,000 watts range. So while there are disadvantages to OCS, Google has created a solution that has far more upsides than there are downsides for them. And over the past 5 years, “tens of thousands of 136x136 port OCS (eight spare ports) were manufactured and deployed.” Google has created a system that works incredibly very well for them.In the future, Google is looking at a larger port count OCS for further scale-out capabilities as well as faster switching speeds to allow wider adoption of OCS in the lower layers of the network. This broader adoption would be tremendously negative to Broadcom, the leader in hyperscale networking switches. Furthermore, Google says they will also continue to improve reliability and lower insertion/return loss.

The low latency of OCS comes from the fact that OCS does not have to decode packets; all they have to do is bounce the incoming light from the source port to the destination port.

Google uses these optical switches in a direct connect architecture to directly connect the leaves through a patch panel. This is not packet switching; this is, for all intents and purposes, an optical cross-connect.

Traditionally the spine of this network uses what is called Electronic Packet Switch (EPS). These are the normal network switches of which Broadcom, Cisco, Marvell, and Nvidia are the leading providers. However, these EPS use a ton of power. Furthermore, every 2 to 3 years, networking speeds have doubled. While this doubling improves power consumption, it also comes with the requirement of upgrading the existing spine EPS. As such, there is always a huge wave of Capex associated with every new generation of Broadcom Tomahawk switch.

Before diving too deep into how their custom networking stack works, let’s quickly discuss what it does and the industry implications. First off, Google claims their custom network improves throughput by 30%, use 40% less power, incurs 30% less Capex, reduces flow completion by 10%, and delivers 50x less downtime across their network.

The EU Renewable Energy Directive and Irish legislation permit the use of GOs.Though using GOs is legal and overseen by the energy regulator in Ireland, ASAI found claims companies were supplying 100 per cent renewable power were misleading to customers.The advertising watchdog said six sections of its advertiser's code of conduct had been broken including one section that says "advertisers should not exploit the credulity, inexperience or lack of knowledge of consumers".

Organisations must demonstrate progress towards their science-aligned reduction targets on a three year cycle to maintain climate positive level certification.

absolute reduction (as opposed to intensity reduction) of category 1 and 2 emissions, aligned to 1.5°C warming

The proposals under the forthcoming Bill are expected to be similar to the CMA’s existing powers in competition matters and would give the CMA the power to decide itself whether consumer law has been broken and impose directions and monetary penalties on companies without having to go through the courts.

This past November, Google Cloud hosted an “emissions hackathon” at the offices of Schlumberger, a Houston oil field services company. The winning team was none other than six Aramco oil and gas data scientists who’d devised a method of using Google Cloud’s machine learning features to detect and repair leaks in methane gas pipelines.

Addressing the nexus of concerns related to water and electricity consumption — along with the associated impact on carbon dioxide emissions — is one of the biggest challenges faced by any big data center operator. In a blog about its new commitment, Brandt reports that water-cooled data centers use about 10 percent less energy than those using methods related to air cooling. Last year, the company estimated that using water cooling helped Google reduce the "energy-related carbon footprint" of its data centers by about 300,000 tons of CO2. 

Klarna which levies money on a per-tonne basis on its own emissions, and uses the funds to finance mitigation projects.

At COP27, governments agreed to create a “contribution unit” as part of the establishment of new carbon markets under the Paris Agreement - a clear sign of support for this evolution in claims

Based on the comparison between carbon emissions and performance, we can observe that the only task in whichbetter performance accuracy has systematically yielded more CO2is image classification on ImageNet, seen on the topright subplot of Figure 4. Still, the relationship is far from being highly correlated (especially given that that the x-axisin on a logarithmic scale).

Another observation that can be made based on our data is that none of the models from our sample were trained ineither Africa nor South America – in fact, the majority of the models from our sample (76) were trained in countriesrepresenting the Global North. This is consistent with previous work examining the ‘digital divide’ in ML and observingthe centralization of power in the field, which hinders researchers from underrepresented locations and groups fromcontributing to the field, given the attribution of computing resources [2,3,9]. Generally speaking, emissions, mattersof equity and accessibility are closely connected to those around climate change, and the centralization of resourcesremains a major problem [33, 34

However, energy-efficientbenchmarks such as HULK [58] have also been proposed, which take computational requirements and environmentalimpacts into account during model evaluation, allowing a comparison of models based on multiple criteria.

Boosting the efficiency of water usage, too, is a priority, with Google Cloud committing to investing in community projects that “replenish 120% of the water we typically consume in our offices and data centres, in a bid to improve  the health of the local watersheds.”

“A staggering 90% of C-level executives said ESG initiatives are a top organisational priority,” says Keeble. “But only 9% are allocating dedicated resources towards sustainability goals.”

Amazon retires, or has retired on its behalf, environmental attributes for Amazon renewable energy projects included in the renewable energy percentage calculation. We may choose to purchase additional environmental attributes to signal our support for renewable energy in the grids where we operate in line with the expected generation of the projects we have contracted.

Among the most deplorable habits of greenwashers is the procurement of unbundled Renewable Energy Credits (RECs). In places like Texas, favorable economics encourage renewable energy deployment, but neither the state energy office nor the grid operator particularly care if the generated electrons are renewable or not. As a result, RECs from these projects are sold separately to offtakers looking to burnish their green credentials.

The top renewable offsets suppliers for Germany-based E.ON SE and Italy-based Eni came from state-backed hydropower projects in China’s Jiangxi and Sichuan provinces, respectively

Yet as of last year renewable offsets remain widespread, despite deep doubts about their efficacy. In the broadest investigation yet of how companies have been relying on junk offsets, Bloomberg Green analyzed 190 million tons of carbon offsets purchased in more than 50,000 transactions in 2021. Close to 40% came from renewable-energy projects. According to Ecosystem Marketplace estimates, the total carbon offsets market was worth $2 billion in 2021.

Lithium resources—concentrations of minerals that are potentially economically viable to extract—are not particularly rare. What matters over the medium and near term is how quickly these resources can be developed into reserves, or minerals that are both recoverable and profitably minable in a given price environment.

Green Mountain Power, Vermont’s largest utility and a creative adopter of grid storage technologies, decided it had some of those cases. The utility bought Nomad’s first large-scale battery trailer, with 1 megawatt/​2 megawatt-hours of storage capacity. GMP currently controls the battery’s charging and discharging at Nomad’s corporate facility in Vermont, while its new ​“home base” docking station gets built, said Josh Castonguay, GMP’s vice president and chief innovation officer. In the meantime, the utility brings out its Nomad unit to support electric-vehicle charging at special events.

The growing number of data centers is expected to drive a 38 percent increase in all electricity sales in Virginia between 2020 and 2035, according to a report by the University of Virginia’s Energy Transition Initiative—an increase of around 44,000 gigawatt-hours per year in electricity use. A gigawatt hour is just about the amount of electricity that 1,000 Virginians on average use in a year. 

Among their chief concerns are the massive amount of stormwater runoff from the millions of square feet of paved over surfaces that would imperil the watershed that provides drinking water for Northern Virginia residents, and the hazardous and noisy construction activities next to residential areas. There are also lingering questions over the impact of energy intensive data centers on the state’s clean energy targets and the true economic benefit for the state. 

The source of this seed funding was provided from Microsoft’s internal carbon tax. Companies that implement carbon taxes should implement mechanisms that recirculate those funds back into individual business group accountabilities in a way that empowers employees to take effective action.

Most future climate scenarios envisage large-scale deployment of so-called “negative emissions,” where we suck CO2 out of the atmosphere in order to keep warming below 2°C. One proposed method for achieving that is “enhanced weathering”—accelerated silicate weathering done by grinding up silicate rock and spreading it on agricultural fields to react with CO2 from the air and fertilize plants at the same time. Brantley’s work shows that for such efforts to be successful, those fields would need a good supply of water and—crucially—would probably need to be plowed regularly to expose fresh minerals to the air. “If you're not going to be turning it over, you'll start to precipitate secondary minerals, and… most of the surface area could be occluded from reaction,” said Brantley.

Over geological time, those landscape proportions have changed in response to shifting tectonic plates. This has changed how efficient silicate weathering has been at removing the CO2 emitted by volcanoes, thereby allowing high CO2 levels and warm climates at times, like in the Cretaceous, or lower CO2 levels and a cool climate when plate tectonics was building lots of “kinetic-limited” mountainous landscapes, like over the last few million years.

The amazing thing is that Microsoft knows that LLM insertion into search will crush the profitability of search and require massive Capex. While we estimated the operating margin shift, check out what Satya Nadella says about the gross margin.

Attributes (and certificates) must be sourced and purchased from within the same defined geographic region that constitutes a “market” for the purpose of transacting and claiming attributes. Ideally this “market boundary” would be clearly defined, but in general it refers to an area in which the laws and regulatory framework governing the electricity sector are sufficiently consistent between the areas of production and consumption. As such, transactions that are both international and intercontinental are not usually appropriate unless there is physical interconnection (indicating a level of system-wide coordination between countries) and ideally if these countries’ utilities or energy suppliers recognize each other’s instruments

Alphabet Inc.’s renewable energy methodology is a custom calculation and is based on a global approach. The numerator includes all renewable energy procured, regardless of the market in which the renewable energy was consumed. Additional details on Alphabet Inc.’s criteria and methodology can be found in theAchieving Our 100% Renewable Energy Purchasing Goal and Going Beyonddisclosure

Renewables and nuclear energy will dominate the growth of global electricity supply over the next three years, together meeting on average more than 90% of the additional demand

More glaring, the company claims that since 2000, it’s cut emissions by 19%. In reality, when excluding RECs from that calculation, Intel’s climate footprint has jumped by more than a third.

The EU’s competition chief Margrethe Vestager on Wednesday also highlighted how Germany and France had accounted for nearly 80 percent of state aid approved under emergency subsidy rules. “European countries are not equal when it comes to state aid,” she said.

When we throw in the fact that some of the parties with the deepest resources, expertise and capabilities in AI are the very same providers of the primitives – providers intent on growth and whose customers are struggling with the size of their respective product catalogs – it’s worth asking whether said providers may be coming around on the idea of a PaaS, but models based on AI rather than prescriptive curation and constraints. One thing, at least, is clear: if any of the above speculation proves true, the industry equilibrium is about to be punctuated.

Sustainability researchers from the Rochester Institute of Technology point out that there is significant variation in the types and amounts of critical materials present in different reservoirs of coal waste. This means that not all waste will be profitable to purify. As the researchers have written, “The value of rare earths in a single ton of coal ash can vary from US$99 at a coal plant in Ohio to $534 at a West Virginia plant. With extraction costs expected to range between $380 and $1,200 per ton, not every coal plant’s ash will be a profitable place to find rare earths.” There are also concerns that the chemicals used to harvest critical minerals could be damaging.

Ziemkiewicz has a picture in his office of himself and Senator Joe Manchin, who has expressed support of his program. “Recycling provides a tremendous opportunity to avoid outsourcing the raw supply of critical minerals we need while creating new economic opportunities right here at home,” Manchin said, at a congressional hearing in the spring. Ziemkiewicz keeps his politics to himself. In the past, he has called himself “a Trotskyite,” but he believes that the success of his past three decades of work, reclaiming thousands of miles of rivers and streams in Appalachia, is based on sharing knowledge across a wide array of communities
