"The transition to renewable energy, it is based on a longstanding ideology. And the longstanding ideology is that human ingenuity can solve our problems." Lisi Krall explains the downsides of renenwable energy, arguing that it isn't the answer to our problems.

This example illustrates the potential for an unintended consequence to move between categories and demonstrates that there are times when it is necessary to review and reflect. What is considered known and knowable changes over time: has the state of knowledge developed or an unintended consequence been identified?

Water-Food-Energy Nexus in Global Cities: Addressing Complex Urban Interdependencies

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.

Tribes, landowners and communities find themselves wrestling with the not-so-green side of green energy.

But that’s just one way to get batteries into low-income customers’ homes. Sunrun also acts as a third-party owner of solar and battery systems that Grid Alternatives installs for customers that can’t or don’t want to borrow money to finance it. Third-party owners can monetize the value of federal tax credits for low-income households that don’t pay a large enough federal tax bill to take advantage of the credits themselves. 

Participants will get zero-interest loans to finance the equipment and installation costs, plus monthly credits in exchange for allowing MCE to tap that equipment to reduce its need to buy high-priced energy during the peak hours of 4 p.m. to 9 p.m. The program is open to households that currently lack rooftop solar as well as households that have already had solar installed by Grid Alternatives and want to take advantage of that self-generated power to heat their homes or charge their cars, said Alexandra McGee, MCE’s manager of strategic initiatives.

"There's so much pressure and emphasis on getting the Green Revolution happening that it's almost by any means necessary without that pause of 'well it is green, but is it as green as it should be?"

how would the energy systems be different in the new system under your Maslow hierarchy framing? 00:43:15 Simon Michaux: I've been giving some thought about what energy actually is and how does it serve us. At the moment, energy is used for transport a lot. So our energy systems will have to empower transport somehow differently. And so this is the whole electric vehicles and buses. So I think the electric system will happen, but at least substantially smaller. 00:43:42 Excuse me. So for example, we would see more buses, more communal transport, and less individual cars. We might have the idea of car sharing where instead of owning a car, we might book a car in. This is the idea of the self-driving car. That might happen in a small scale. It won't be enough to replace our existing systems. 00:44:05 So the form of energy comes when it comes. It will be different to what we have now. And everything around it, including our technology, will have to evolve. And part of that I can see for example, instead of one big giant seamless power grid that delivers sinusoidally pure power all the time, and our electronics cannot cope with anything else, I can see a situation where we will evolve an engineering electronics that can 00:44:29 cope with variable power. So if a power grid goes up or down, if we get power blackouts, it doesn't cook the electronics. So instead of seamless, we now have a non-linear production of power and its outcomes. So that means- Nate Hagens: There would be no demand for such a product now. Simon Michaux: No, no. Because no one thinks it's necessary. So if instead of one big grid, we had lots of micro grids that are connected together. 00:44:54 And they sometimes transfer power between them. And sometimes when things get difficult, they could shut down one or all of them without actually damaging themselves and they could start up at any time. And each of those micro power grids will be around an industrial activity of value. For example, a power grid will be around a hospital. And that hospital will then also be surrounded by a community of people who operate that 00:45:18 hospital. And the food systems for that hospital, but all comes off that one power grid. It's reason to be is that hospital. And we might attach schools to it, that sort of thing. And so our energy will be organized very differently. And so it may well be things like solar panels, wind turbines. But we should also consider unconventional stuff, like some of the really weird ones, like the kinetic kites are an unusual energy system. 00:45:43 I don't know if they're viable in the current environment. But if things get more difficult, we might try such things. All unconventional and unorthodox ideas must be looked at and taken seriously, and the alternative is we go without. That's how I sort of see energy going.

But 80% of the sector is already off fossil fuels. Our entire transport sector is fossil fuels. And that's actually the main challenge. But we've got a lot of heavy industry here like smelters and factories, and they're all 00:03:52 running on non fossils fuel energy. And so we can actually run an industrial sector without fossil fuels right now, which is amazing.

today what I'd like to do, if you're willing, is start to construct a framework for how we start to prepare for what's ahead. What is the hard work that's going to make need to be done? And what are the buckets that people and governments need to focus on?

France moves to ban short-haul domestic flights

Der österreichische Energieverbrauch beträgt zirka 404 TWh (1 Terawattstunde = 1012 Wattstunden) und steigt jährlich um mehr als 2 %. Etwa 25 % davon stammen aus erneuerbaren Energiequellen. Eine grobe Betrachtung zeigt, dass etwa je ein Drittel des Energieverbrauchs auf Verkehr, Industrie und andere Verbraucher entfällt. Ein Anteil von etwa 60 TWh wird in der Form von elektrischer Energie verbraucht. Durch die günstigen natürlichen Gegebenheiten in Österreich können etwa 60 % davon aus Wasserkraft gewonnen werden. Auf Grund des stetig steigenden Verbrauchs und in geringerem Ausmaß wegen der Liberalisierung der Strommärkte erzeugt Österreich seit dem Ende der 90-er Jahre auch bei der Elektrizität nicht mehr selbst seinen Eigenbedarf. Im europäischen Vergleich hat Österreich - vor allem auf Grund der Wasserkraft - einen hohen Anteil an erneuerbarer Energie. In Europa erfolgt die Stromgewinnung zu etwa 85 % aus fossilen Rohstoffen sowie Kernenergie und zu 15 % aus erneuerbaren Quellen. Es ist also derzeit in allen Bereichen eine überwiegende Abhängigkeit von fossilen Energieträgern gegeben.

The novelist and screenwriter Raymond Chandler said he avoided reading books written by someone who didn’t “take the pains” to write out the words. (It used to be common for writers to dictate into a recorder then have an assistant transcribe those words.) “You have to have that mechanical resistance,” Chandler wrote in a 1949 letter to actor/writer Alex Barris. “When you have to use your energy to put those words down, you are more apt to make them count.”

Renewable energy critics argue that wind and solar are not reliable sources because of their variability. Others argue that wind farms encroach on pristine environment and destroy a country’s natural habitat, as is the case with the installation of thousands of wind turbines on scores of Greek islands in the Aegean Sea. How would you respond to such concerns, and are there ways around them?

How Fast a Low Carbon Transition? Or: Is Vaclav Smil Wrong?

here are those same numbers compared 00:41:21 against reported global reserves so there's the amount of metal we need and there is the global reserves this column is the proportion of metals required to 00:41:33 phase out fossil fuels as a percentage that is of all the copper we need to make one generation of units current global reserves will get us 19.23 00:41:45 of the way there we don't have enough copper for one generation

we used to have 500 years ago a small human system a big pile of natural resources and a small pollution plume 00:46:47 an industrial ecosystem of unprecedented size and complexity that took more than a century to build with support of the highest calorifically dense source of cheap energy the world has ever known that would be oil 00:46:59 in abundant quantities with easily available credit and unlimited mineral resources and now we've got a system that's a human system that's really large 00:47:10 a depleted natural resources [Music] portfolio compared to what we had but we've now got a massive pollution stream so now we seek to build an even more complex system with very expensive 00:47:24 energy a fragile finance system saturated in debt not enough minerals with an unprecedented number of human population embedded in a deteriorating environment 00:47:35 so at this point i'm going to say this is probably not going to go as planned

it also is summed together so everything we need is summed together per metal and that gives us this column here total metal required to produce one generation of technology units to phase 00:40:15 out fossil fuels and so that the that we've got these numbers here the next column is global metal production as it was from mining in 2019 00:40:28 so this is all from the usgs and the bgo the final column is how many years of production at the 2019 rate um would be needed to hit the actual 00:40:42 volumes needed so 2019's the last year before covert is the last year of stable data that's why i've used it so you might notice some of these numbers are rather large 00:40:55 like we will need seven thousand one hundred and one years of production to produce the needed number of volume of vanadium that's your uh your redox batteries

the idea that we're going to do this in seven or eight years is very amusing so then the question is oh we'll just open more mines it's simple right

if we want to deliver a thousand terawatt hours a year using these systems you could use 142 00:29:07 coal-fired power stations or 30 000 solar pv arrays or 12 309 wind turbine arrays of average size 00:29:18 where each array is like 10 win windows this is this is where we're getting the extra numbers from so each of these sites will have to be built and constructed and maintained and then when they wear out they need to 00:29:30 be decommissioned so renewables have a much lower energy return on energy invested ratio than fossil fuels and they and the the truth is they may not be strong enough to power the next industrial era 00:29:45 so gas and hydro power generation has to balance with demand supply and demand has to balance otherwise the grid will age

let's put the electrical power systems together these electrical power 00:22:29 systems that this is actually on the low side because most industrial action happens with the consumption of coal and gas on site and then it's converted to energy on site this is what's just been drawn off the power grid 00:22:42 so there's a vast amount of energy associated with manufacturing that is not included here and that is actually a huge piece of work to include that so these numbers i'm showing you are very much on the low side 00:22:55 so we're going to put it all together we need 36 000 terawatt hours all there abouts that's a that's a very low estimate

assessment of extra capacity required of alternative energy electrical power systems to completely replace fossil fuels

Results indicate that participants were more likely to interact with their smartphone the more fatigued or bored they were, but that they did not use it for longer when more fatigued or bored. Surprisingly, participants reported increased fatigue and boredom after having used the smartphone (more). While future research is necessary, our results (i) provide real-life evidence for the notion that fatigue and boredom are temporally associated with task disengagement, and (ii) suggest that taking a short break with the smartphone may have phenomenological costs.

As Raymond Chandler put it, “when you have to use your energy to put those words down, you are more apt to make them count.”

The energy sector contains a large number of long‐lived and capital‐intensive assets. Urban infrastructure, pipelines, refineries, coal‐fired power plants, heavy industrial facilities, buildings and large hydro power plants can have technical and economic lifetimes of well over 50 years. If today’s energy infrastructure was to be operated until the end of the typical lifetime in a manner similar to the past, we estimate that this would lead to cumulative energy‐related and industrial process CO2 emissions between 2020 and 2050 of just under 650 Gt CO2. This is around 30% more than the remaining total CO2 budget consistent with limiting global warming to 1.5 °C with a 50% probability (see Chapter 2)

now we talk i talk about a few ideas good regulators requisite variety self-organized criticality and then the 01:35:04 free energy principle from active inference um and uh maybe i'll just try to briefly talk mention what's what those means for what those ideas mean for people who 01:35:15 aren't familiar so good regulator really came from the good regular theorem or whatever it's called really came from cybernetics ash ashby yeah a lot his law of requisite 01:35:33 variety and uh the it's the concept is that a organism or a you know a system must be must be a model of that which it but 01:35:47 that needs to control

In basic English, “it takes two coal workers, 169 solar workers and 1,100 wind workers to equal the work of one natural gas worker.”

Energy efficiency has never been more crucial! The time to unleashing its massive potential has come

The advantage of ocean currents is their stability. They flow with little fluctuation in speed and direction, giving them a capacity factor — a measure of how often the system is generating — of 50-70%, compared with around 29% for onshore wind and 15% for solar.

One example of a siloed approach to critical infrastructure is the European Programme for Critical Infrastructure Protection’s framework and action plan, which focuses on reducing vulnerability to terror attacks but does not consider integrating climate or environmental dimensions.39       Instead of approaching critical infrastructure protection as another systems maintenance task, the hyper-response takes advantage of ecoinnovation.40 Distributed and localized energy, food, water, and manufacturing solutions mean that the capacity to disrupt the arterials that keep society functioning is reduced. As an example, many citizens and communities rely on one centralized water supply. If these citizens and communities had water tanks and smaller-scale local water supply, this means that if a terror group or other malevolent actor decided to contaminate major national water supplies—or if the hyperthreat itself damaged major central systems—far fewer people would be at risk, and the overall disruption would be less significant. This offers a “security from the ground up” approach, and it applies to other dimensions such as health, food, and energy security.

The steel tower is a giant mechanical energy storage system, designed by American-Swiss startup Energy Vault, that relies on gravity and 35-ton bricks to store and release energy.

While heat pumps are the most cost effective way to use electricity to heat your home during the cooler months, leaving them running day and night is not economically efficient. According to Energywise, you should switch off your heat pump when you don’t need it. This is to avoid excessive energy waste.

A related risk is that the coverage will have gaps. California is a choice spot for installing chargers, but is anyone keen on investing in Nebraska?

By 2040 around 60% of all charging will need to take place away from home,

Today’s mostly wealthy owners can often plug in their EV at home or at work. But many less-well-off EV drivers will not have a drive in front of their house or a space in the executive car park.

Yet the charging business suffers from big problems. One is how to co-ordinate between the owners of charging points, the owners of the sites where they will be installed, planning authorities and grid firms.

As the emerging field of energy humanities (168) is beginning to show, the traditions, cultures, and beliefs of contemporary, industrial societies are deeply entangled with fossil fuels in what have been called petrocultures and carbonscapes (169). Future visions are dominated by such constrained social imaginaries (170), and hence rarely offer a “radical departure from the past” (171, p. 138).

Similar to my recent musings (link coming soon) on the dualism of matter vs information, I find that the real beauty may lie precisely in the complexity of their combination.

You aren't wasting energy inventing class names. No more adding silly class names like sidebar-inner-wrapper just to be able to style something, and no more agonizing over the perfect abstract name for something that's really just a flex container.

In order to measure energy, we need a unit for it. In the metric system, the standard unit of energy is the joule. The formal definition of a joule is: A joule is the amount of energy expended when an object is moved 1 meter against a resisting force of 1 newton. (You can learn all about the concept of force in a physics class.) As for the joule, here are some statements that may help you visualize this unit.  A joule is… …enough energy to lift a one kilogram object 10.2 centimeters. …enough energy to heat one milliliter of water from 20ºC to 20.24ºC. …enough energy to keep a 60 watt light bulb glowing for 0.0167 seconds. Obviously, a joule is a very small amount of energy, and in fact it is an inconveniently small amount when we describe chemical reactions. Chemists usually report energies for reactions in kilojoules (1 kJ = 1000 J).

sectoral break-up of PPP projects, we would find that almost all of the projects have come up in economic infrastructure (power, transport, and telecom) compared to social infrastructure.Social infrastructure (like water supply, solid waste management, health and education) have low cost-recovery and, consequently, face massive resource-crunch.
