For the fourth year in a row, Europe has reduced its carbon dioxide emissions, with CO2 output falling by 1.3 percent in 2008.

The recession appears to be the main factor in the emissions reduction, as factories were idled across the continent. But European Union Environmental Commissioner Stavros Dimas said the EU’s emissions trading scheme and development of renewable energy sources also is playing a part in the reduction.

“This is a timely message to the rest of the world in the run-up to the Copenhagen climate conference,” said Dimas.

NPR’s Morning Edition recently aired this story, a variation on a theme that I have written about in the past on CleanTechies and in scholarly work: green backlash against renewable power. The Morning Edition piece focused on the land use implications of renewables, noting that it takes a lot more land to generate a terawatt of solar, wind or biofueled electricity than of coal or natural gas power.

True enough. But, for me, it all comes down to the threshold question: do you believe the worst-case climate scenarios? If your answer is yes, and you have the courage of those convictions, then you realize — as I have — that we have no choice, and no time to dawdle. People who answer that question affirmatively know that the paradigm shifts in energy production and consumption that are necessary if we are to have any chance of righting our climatological ship will face knee-jerk opposition and demagoguery from opponents (s, e.g., the spring time bloodbath over the Waxman-Markey bill). A movement that remains — however gallingly — on such tenuous footing cannot afford to endure the additional obstacle of in-fighting over policy nuances. To twist a familiar and over-used metaphor:

Israeli solar energy companies such as Solel Solar, Aora, Ormat technologies, and a host of others are now world leaders in the development of sun power to produce electricity. But Israel, a small country of 7 million, with more than half its land area being desert, has been a solar energy pioneer virtually since its beginning in 1948.

What is now fondly known to many Israelis as a “dude shemesh”  or  sun boiler, was invented by a guy named Levi Yissar back in the early 1950’s, when electricity was very expensive due to a severe energy shortage.

A significant majority of Americans supports President Obama’s efforts to overhaul energy policy and a slight majority favors a controversial program to place a cap and price on carbon dioxide emissions, according to a Washington Post-ABC News poll.

The poll found that nearly 60 percent of Americans back administration and congressional efforts to combat climate change and develop renewable energy and 55 percent approve of Obama’s handling of the issue, compared with 30 percent who do not.

Imperial County, tucked away in the southeastern corner of California, has long suffered from perennial unemployment rates exceeding 20 percent.

Yet Imperial County is also home to the “crown jewel” of all geothermal steam resources in the U.S., making it a prime spot to showcase how renewable energy can help spur the new green economy so enthusiastically touted by the Obama Administration.

Late December, the California Public Utilities Commission (CPUC) approved the construction of the $1.9 billion Sunrise PowerLink transmission line, which could send clean electricity from Imperial County to San Diego. However, the Center for Biological Diversity (CBD) petitioned the California Supreme Court last January to review this decision, citing San Diego Gas & Electric’s (SDG&E) refusal to guarantee that the transmission project would be reserved exclusively for renewable energy resources.

The future prospects of companies involved in electric vehicles continue to be greatly influenced by the support (or lack thereof) from the federal government. This week the government handed out another $300 million in funding for alternative fuel programs to Clean Cities initiatives around the country.

Of the 25 Clean Cities initiatives that received funding, 10 involved electric vehicles or vehicle charging stations. These projects will provide much-needed income to companies that produce batteries, vehicles, and charging stations. During this tight economy, even small orders such as these can provide a life line to startup companies looking for capital, as well as boost investor confidence.

Author and scholar Michael Levi says in the current issue of Foreign Affairs that the odds of signing a climate treaty in Copenhagen this December are extremely small and argues that policymakers and environmental advocates should rethink their expectations for the summit.

Levi, a senior fellow for energy and environment at the Council on Foreign Relations, contends that the conventional treaty model – which focuses on high-level agreements on emissions caps and carbon trading schemes – is fundamentally flawed because emissions caps are largely unverifiable and unenforceable. Short of bullying with punitive sanctions, nothing can be done if caps are exceeded.

The U.K.’s Institute of Mechanical Engineers has proposed three geo-engineering schemes officials say could be immediately implemented to slow global warming: building artificial trees that absorb large amounts of carbon dioxide, using algae tubes to pull CO2 from the atmosphere, and painting the roofs of buildings white.

The engineers said that these three ideas, if carried out on a wide scale, could absorb much of the CO2 produced annually in the U.K. and cool temperatures.

The engineers shied away from more ambitious geo-engineering proposals — such as seeding the oceans with iron to encourage the growth of CO2-absorbing plankton — and focused instead on practical solutions that could be carried out soon.

For the first time, scientists have discovered chemicals used in a controversial natural gas drilling technique in water wells near the gas sites.

Scientists for the Environmental Protection Agency (EPA), testing wells near a major gas drilling area in Wyoming, have found traces of drilling chemicals in three wells, and other contaminants — including oil, gas, and heavy metals — in 11 of 39 wells recently tested, according to the Web site Pro Publica.

The chemicals are used in a process called hydraulic fracturing, in which drilling fluids and sand are injected under high pressure to break up rock and release gas.

umissgym: Is it just me, or is it hot in here?

The social media craze has hit building automation, as the campus at the University of Mississippi will soon be broadcasting its energy consumption via Twitter and Facebook updates.

In partnership with smart grid company SmartSynch, Ole Miss has created online feeds (also via RSS) detailing several of its main buildings’ energy use, ostensibly to “alter behavior to reduce electricity consumption and carbon emissions.” The UMiss project will study consumption from lighting, temperature controls, and appliances. The organizations have created an online application to monitor and report the energy draw so that building operators can learn where energy is being wasted and implement new conservation strategies.
