    1. Their model also raises the question of scale: unlike Facebook, whose mission has always been to accommodate and connect everyone, everywhere, Low Tech supports the idea that a website can serve a small community connected through common interests. The Internet's global accessibility has lead us to think on a massive scale, but a community that lacks physical proximity can still be “local” in mindset.
    2. Perhaps because it was conceived as a utopia, we tend to think of the internet as a limitless superhighway, a virtual mirror free from the constraints of our physical world. Data, files, our work, our memories, all float up to the cloud and are called down to attention by what seems to be magic. Yet in reality, life online is governed by the same limits to growth affecting the rest of our world. According to Low Tech Magazine the entire World Wide Web is responsible for consuming 10% of all global electricity production, a rate that is exponentially increasing.

    1. a range of business models

      I think Hypothes.is plays a very important role in democratising these discussions. The real places where these decisions are made are often closed off to faculty and students. We need to have serious discussions about which sustainability models are appropriate for education not just the businesses. What is sustainable for education may not always be sustainable for business!

    1. The Politics of Sustainability and Development

      This reading is to help you better understand the role and importance of literature review. Literature review connects us to a bigger community of scientists who study the same research topic, and helps us build up, illustrate, and develop our theory (what is happening between the IV and the DV?) and research design (how one plans to answer the RQ).

    1. The first week of class was pretty similar to most first weeks of a programs I have experienced. However, this program was a little more hectic due to the fact that we have so many programs trying to do so many different and connected things. The moment that stood out the most to me was how much work was accomplished in 8 short hours by the MTA changemakers, this was impressive and inspiring to me. I participated in a similar group last quarter. In that program we  had weeks to get the point that they got to in an afternoon.

      You know, upon reading the textbook Networks, Crowds, and Markets, I came to see that when networks are first formed, they tend to be hectic and that there is a scram for connections in order to get a project or anything started. However, as time goes by and the networks began to get familiarized with themselves, I found that they start to form groups that are more stable and cohesive with one another and will start building up momentum in order to build something great. However, this comes with the understanding of trust and mutual bonds and without it, it will not become a teampreneurship but instead it becomes just a regular classroom setting that is just doing a series of movements on various different projects. Thus, through reading your blog and other people's blogs, I came to see that there is a stage in which teampreneurship must go through in order to be called teampreneurship and this goes the same with any enterprises. Guess it is the key towards understanding sustainability.

    1. So, the UN forecasting model inputs three things: fertility rates, migration rates, and death rates. It doesn’t take into account the expansion of education for females or the speed of urbanization (which are in some ways linked). The UN says they’re already baked into the numbers. But when I went and interviewed [the demographer] Wolfgang Lutz in Vienna, which was one of the first things we did, he walked me through his projections, and I walked out of the room gobsmacked. All he was doing was adding one new variable to the forecast: the level of improvement in female education. And he comes up with a much lower number for global population in 2100, somewhere between 8 billion and 9 billion.

      Makes sense

    1. while we like to scoff at all the mucky-muck bureaucracy around training, budgets, policy and messaging, it’s precisely that stuff that prevents your dream initiative of today morphing into rotting infrastructure of tomorrow. It’s all too easy in this business to end up the new interactive whiteboard — bought one year as the must-have accessory and abandoned the next.

      Good reminder of how essential it is to take time from the evangelism of OER to write and enact some policy to ensure sustainability of our OER efforts.

    1. Individuals are most creative when provided space to follow their interests without sanction, when support and guidance are readily available, and when social community is fostered.

      "Support and guidance" is tricky. They're not binaries that are or are not available; they're large matrices of forms and degrees.

    2. My work, rooted in both theory and practice, reveals three things that are essential to bringing individuals into the circle of change: autonomy, guidance, and a sense of social community, or working toward a larger meaningful goal.

    1. Most do not contribute anything back to PKP

      Consider working with the 2.5% Commitment group. They are leading a movement to organize libraries to direct some of their funding to support open infrastructure.

    1. Average land use area needed to produce one unit of protein by food type, measured in metres squared (m²) per gram of protein over a crop'sannual cycle or the average animal's lifetime. Average values are based on a meta-analysis of studies across 742 agricultural systems andover 90 unique foods.

      Beef is nearly 6 times the impact of Pork.

      This is worth referring to in the background section to provide context, on why you need more than just changes to the web

    1. The International Energy Agency said today that it was significantly increasing its five-year growth forecast for renewables thanks to strong policy support in key countries and sharp cost reductions. Renewables have surpassed coal last year to become the largest source of installed power capacity in the world.

    1. A local company named AeroFarms has built what it says is the world's largest indoor vertical farm, without the use of soil or sunlight.

      Its ambitious goal is to grow high-yielding crops via economical methods to provide locally sourced food to the community, protect the environment and ultimately even combat hunger worldwide.

      "We use about 95 percent less water to grow the plants, about 50 percent less fertilizer as nutrients and zero pesticides, herbicide, fungicides," said David Rosenberg, co-founder and chief executive officer of AeroFarms.

    1. But EEI, its member utilities, Koch-backed groups, and their corporate and conservative allies have been lobbying states, sometimes successfully, to eliminate net metering or otherwise reduce the financial incentives for clean home power generation. When they succeed, people with solar leases could end up with less in savings on their electricity bill than the cost of renting their solar array. EEI’s letter feigns concern for these consumers — an impressively cynical maneuver, as it’s the very group leading the push to raise those consumer costs.

    1. Beavers are great for water conservation: they create ponds by damming creeks, and they also dig to make them deeper.

      We could be collecting the rain water that flows off our roofs (and also elsewhere), but very few people do -- at least not in the US.

    1. John Quiggin points out that we have consumption peaks, as well as production peaks. Coal, oil, steel, and paper usage per person have all declined. If I understand him, then the per person rates have declined enough to create a decline in total consumption, in spite of population growth.

    1. IPCC: Solar & biomass produce 3.5 - 21 times more carbon emissions (eq.) per kilowatt-hour than nuclear & wind.

      Is this right? If so, that's disappointing for solar. But it shows wind as lower CO2 than nuclear. (And the chart doesn't show fossil fuels. Is solar favorable compared to them?)

    1. Elinor Ostrom shared the 2009 Nobel Prize in Economics for her work on governance of the commons -- finite resources shared by a community. She studied such communities, and derived eight principles, which are summarized on this page and on Wikipedia.

    1. Such self-management oftenworks well, but it is also contingent uponthe costs and complexities of spare parts andrepairs, as well as the underlying economiccohesion of the neighborhood—in terms ofits ability to hold on to specific values anduses of land and the demographic stabilityof its inhabitants.

      All pieces of the puzzle must come together in order for infrastructure to remain stable. If someone does not have the right tools or access to information, they are helpless to sustain the power of the infrastructure.
