GE Energy Financial Services has released a study estimating that the federal production tax credit (PTC) for wind power that is set to expire December 31, 2008 more than pays for itself through tax revenues from the projects' income, vendors' profits and individual workers' wages.

The RMI study, "Assessing the Electric Productivity Gap and the U.S. Efficiency Opportunity," determines the productivity rate of each state by measuring how much gross domestic product is generated for each kilowatt-hour consumed.

A study conducted by Stanford University confirmed that interconnected multiple wind farms can be used to provide baseload electric power. Interconnecting wind farms with a transmission grid reduces the power swings caused by wind variability and makes a significant portion of it just as consistent a power source as a coal power plant. "This study implies that, if interconnected wind is used on a large scale, a third or more of its energy can be used for reliable electric power, and the remaining intermittent portion can be used for transportation, allowing wind to solve energy, climate and air pollution problems simultaneously," said Archer, the study's lead author and a consulting assistant professor in Stanford's Department of Civil and Environmental Engineering.

There is significant potential to improve the energy efficiency of commercial refrigerators, boilers and water heaters, according to the latest three studies carried out under the EU's energy-using products (EuP) directive.

Two of these – on imaging equipment and electric motors – are expected this month.

LONDON (Reuters) - Many wind turbines mounted on homes in British cities are contributing to global warming, not fighting it, according to a new study.

The implementation of new high-speed transport technologies re-shapes the demand balance between transport modes and rebound effects may occur. In this paper first a definition of environmental rebound effects of high-speed transport is presented and various cases are discussed. Second, a method is developed to determine and quantify the environmental rebound effects employing life cycle assessment. The method is illustrated in a case study by investigating the greenhouse gas emissions of a frequently discussed future underground maglev train system for Switzerland.

Molten salt is already used in some applications in the chemical industry to dampen temperature fluctuations in reactors.

The study, titled "Cleantech and Venture Capital: A Whirlwind Romance or Just Dating?", is from the Topline Strategy Group, a Newton consulting and market research firm.

Widespread adoption of PHEVs could reduce GHG emissions from vehicles by more than 450 million metric tons annually in 2050—equivalent to removing 82.5 million passenger cars from the road. Cumulative GHG emissions reductions from 2010 to 2050 could reach 10.3 billion metric tons under the most aggressive scenarios for the development of a lower-carbon electrical infrastructure and PHEV penetration.

Unique in its scope, the 18-month study of global energy to 2030 involved more than 350 experts from diverse backgrounds and organizations—the majority of them from outside the oil and gas industry.

KEMA, in partnership with the civil engineering firm Bureau Lievense and technology illustrators Rudolph and Robert Das, has developed an "Energy Island" concept to store power generated from an offshore wind farm. The concept design is the initial result of an on-going feasibility study being conducted for Dutch energy companies.

According to a new study that reviewed fossil fuel and energy subsidies for Fiscal Years 2002-2008 was just released by the Environmental Law Institute and discovered that the U.S. spends about two-and-a-half times as much on fossil fuels (mostly aiding foreign oil production) than it does on renewable energy.
