Where's the coldest spot in the universe? Not on the moon, where the temperature plunges to a mere minus 378 Fahrenheit. Not even in deepest outer space, which has an estimated background temperature of about minus 455°F. As far as scientists can tell, the lowest temperatures ever attained were recently observed right here on earth.

Climate Change Messaging: Avoid the Truth » CounterPunch: Tells the Facts, Na... - 1 views

Ted Nordhaus and Michael Shellenberger published the op-ed “Global Warming Scare Tactics” in the New York Times on April 8. Participants in recent debates over climate change may recognize their names. They’re the guys who run the Breakthrough Institute, a pseudo-contrarian “environmental research organization.”

While occasionally on point in its charges against the big organizations, the essay (based on interviews with mostly white male leaders of large national groups) had nothing to say about the environmental justice movement, or other grassroots groups led by women and people of color. It neglected as well the environmental movements of the Global South, today the heart of the climate justice movement.

Is fear of disruption of what Habermas calls the life-world the sole inducer of civic action? Of course not: social movements also cohere around other shared, negotiated understandings, identities, diagnoses of problems, and assessments of opportunities. Might fear paralyze rather than mobilize? Yes: in cases when the perceived threat appears impervious to resistance, and when commitment to the cause flags over time. Fear-based campaigns require a tangible evil: a draft card, a nuclear plant cooling tower, a polluting facility’s smoke plume, an Operation Rescue picket line.

This Changes Everything: Capitalism vs the Climate review - Naomi Klein's powerful and ... - 0 views
-
Much of this book is concerned with showing that powerful and well-financed rightwing thinktanks and lobby groups lie behind the denial of climate change in recent years.
-
Klein interprets the marginalisation of climate change in the political process as the result of the machinations of corporate elites. These elites “understand the real significance of climate change better than most of the ‘warmists’ in the political centre, the ones who are still insisting that the response can be gradual and painless and that we don’t need to go to war with anybody… The deniers get plenty of the details wrong… But when it comes to the scope and depth of change required to avert catastrophe, they are right on the money.”
-
Klein is a brave and passionate writer who always deserves to be heard, and this is a powerful and urgent book that anyone who cares about climate change will want to read. Yet it is hard to resist the conclusion that she shrinks from facing the true scale of the problem. When I read The Shock Doctrine (Guardian review headline: “The end of the world as we know it”), I was unconvinced that corporate and political elites understood what they were doing in promoting the wildly leveraged capitalism of that time, which was already beginning to implode. The idea that corporate elites are in charge of the world is even less convincing today. The neoliberal order has recovered, and in some countries even achieved a spurious kind of stability, but only at the cost of worsening global conflicts.

The Anthropocene Myth | Jacobin - 0 views
-
Who’s driving us toward disaster? A radical answer would be the reliance of capitalists on the extraction and use of fossil energy. Some, however, would rather identify other culprits. The earth has now, we are told, entered “the Anthropocene”: the epoch of humanity. Enormously popular — and accepted even by many Marxist scholars — the Anthropocene concept suggests that humankind is the new geological force transforming the planet beyond recognition, chiefly by burning prodigious amounts of coal, oil, and natural gas.
-
The important thing to note here is the logical structure of the Anthropocene narrative: some universal trait of the species must be driving the geological epoch that is its own, or else it would be a matter of some subset of the species. But the story of human nature can come in many forms, both in the Anthropocene genre and in other parts of climate change discourse.

Giving short shrift to all the talk of a universal human evildoer, she writes, “We are stuck because the actions that would give us the best chance of averting catastrophe — and would benefit the vast majority — are extremely threatening to an elite minority that has a stranglehold over our economy, our political process, and most of our major media outlets.”

Why the GOP's Attack on Obama's Climate Plan Will Probably Fail | Mother Jones - 0 views

But for now, there's a pretty good chance today's hearing was just a warm-up round for a much more serious fight yet to come. At this point, says Sierra Club chief counsel Joanne Spalding, the EPA's opponents "are trying to derail a train that's still in the station."

Taking the holistic view, one can understand how some of the most basic conditions of life are threatened by a basic contradiction. Civilization, the quintessential expression of Enlightenment values that relies on ever-expanding energy, threatens to reduce humanity to barbarism if not extinction through exactly such energy production.

or every farmer or rancher who has leased his land for drilling, there are many homeowners living nearby who get nothing but the shitty end of the stick: pollution, noise and a loss of property value.

What gives the film its power is the attention paid to people like Stevens who organized petition drives and showed up at town council meetings to voice their opposition to fracking. They look like Tea Party activists or Walmart shoppers, mostly white and plain as a barn door, but they know that they do not want drilling in their townships and are willing to fight tooth and nail to prevent it. For all of the left’s dismay about its lack of power, the film’s closing credits reveal that there are 312 local anti-fracking groups in Pennsylvania made up of exactly such people who will likely be our allies as the environmental crisis deepens.

Renewable energy in Europe - approximated recent growth and knock-on effects - European... - 3 views
-
This report introduces several methods the European Environment Agency (EEA) has developed for assessing and communicating early RES growth and the important knock-on effects that RES growth has on the energy sector and related areas. The report provides specific information at EU and country level on estimated RES progress in 2013, estimated gross avoided carbon dioxide (CO2) emissions and avoided fossil fuel use due to the additional use of renewable energy since 2005, as well as an assessment of the statistical impacts of growing RES use on primary energy consumption.

Grid-scale energy storage applications in renewable energy integration: A survey - 2 views
-
This paper examines both the potential of and barriers to grid-scale energy storage playing a substantive role in transitioning to an efficient, reliable and cost-effective power system with a high penetration of renewable energy sources. Grid-scale storage is a term that describes a number of different technologies with a wide range of characteristics. This versatility leads to the use of storage to perform a number of grid-services. We first enumerate these services, with an emphasize on those that are best suited to mitigate the effects of uncertainty and variability associated with intermittent, non-dispatchable renewable energy sources. We then provide an overview of the current methods to evaluate grid-integrated storage, summarize key findings, and highlight ongoing challenges to large-scale adoption of grid-scale energy storage. We focus on one particular area that is critical to both the efficient use of energy storage in the power grid and its long-term economic viability: the conflict between the technical benefits of this resource, which can provide both power and energy related grid-services (in some cases simultaneously), and the economic challenges of compensating these services within the current market structures. We then examine recent progress in addressing these issues through regulatory changes and other initiatives designed to mitigate previous market failures. This discussion is followed by some remarks about ongoing regulatory and market design challenges. The paper closes with a summary of the ideas presented and a discussion of critical research needs.
Capital-energy substitution: Evidence from a panel of Irish manufacturing firms - 2 views
-
"We use a translog cost function to model production in the Irish manufacturing sector over the period from 1991 to 2009. We estimate both own- and cross-price elasticities and Morishima elasticities of substitution between capital, labour, materials and energy. We find that capital and energy are substitutes in the production process. Across all firms we find that a 1% rise in the price of energy is associated with an increase of 0.04% in the demand for capital. The Morishima elasticities, which reflect the technological substitution potential, indicate that a 1% increase in the price of energy causes the capital/energy input ratio to increase by 1.5%. The demand for capital in energy-intensive firms is more responsive to increases in energy prices, while it is less responsive in foreign-owned firms. We also observe a sharp decline in firms' responsiveness in the first half of the sample period."
Logging Occupancy to Optimize Energy Use - Energy Efficiency Markets - 2 views
-
Every occupant in a building creates demand for lighting, ventilation, thermal comfort, and electrical power. Lighting, heating, and cooling unoccupied spaces is a huge source of energy waste in buildings, and many studies have shown that building occupancy profiles have a significant impact on building energy use and operational controls. Closer alignment of occupancy patterns to building equipment schedules can be an effective low-cost/no-cost energy efficiency strategy leading to more intelligent control of buildings, a better balance between occupant comfort and energy savings, and lower utility bills. This includes, but is not limited to, HVAC temperature set points, lighting schedules, and economizer schedules.
