"A new study by the Department of Energy's National Renewable Energy Laboratory (NREL) has revealed that U.S. wind resources are far greater than previously believed. The study, a collaborative project between NREL and AWS Truewind, LLC, of Albany, New York, created resource maps and wind potential tables for 48 states. The recent study is the first comprehensive update of the wind energy potential by state since 1993. The resource maps for the contiguous United States, and separately for each state, show the predicted mean annual wind speeds at 80-meter height. They are derived from 200-meter resolution maps developed by AWS Truewind for the windNavigator system. Areas with annual average wind speeds around 6.5 m/s and greater at 80-meter height are generally considered to have suitable wind resources for wind development"

Concentrating solar power (CSP) is an emerging technology that offers the potential to supply utility-scale peaking power competitively. In December 2008, a 1.5 MWe solar thermal central receiver system was declared operational by plant construction company Kraftanlagen Munchen. Although solar tower technology had been built as early as the 1970s and a second commercial tower is now close to completion (see REW magazine July/August 2008) the so-called Test and Demonstration Power Plant Julich, in Germany, is the world's first solar thermal power plant erected which uses air as the medium for heat transport. In all previous plants liquid media such as molten salt or oil have been used for the obvious reason of their high specific heat capacity, which in turn results in low volume flow rates and low pumping losses.

Internet search giant Google - sometimes criticised for the amount of energy its servers use - now aims to do for the power grid what it did for the web. Having conquered the market for web search by first simplifying how it is done and then linking advertising to users' search terms, Google Inc is now funding green technology and using its brand power to lobby for policy change.

Will support energy efficiency efforts nationwide that will create 87,000 jobs and cut energy bills for families Washington DC -- Vice President Joe Biden and Energy Secretary Chu today detailed an investment of nearly $8 billion in state and local weatherization and energy efficiency efforts as part of the President's American Recovery and Reinvestment Act. With an investment of about $5 billion through the Weatherization Assistance Program and about $3 billion for the State Energy Program, the Department of Energy will partner with state and local governments to put 87,000 Americans to work and save families hundreds of dollars per year on their energy bills. To jump-start job creation and weatherization work, the Department of Energy is releasing the first installment of the funding - about $780 million -- in the next few days. The Department will release additional funding over time as states demonstrate that they are using the funding effectively and responsibly to create jobs and cut energy use.

Former Vice President Al Gore said on Thursday that Americans must abandon fossil fuels within a decade and rely on the sun, the winds and other environmentally friendly sources of electric power, or risk losing their national security as well as their creature comforts.

Plan C is a luminous book. Whereas so many other books on curtailing energy usage simply describe ways to cut consumption, Plan C goes way beyond mere description to take a truly penetrating look at how our individual choices make a difference. Author Pat Murphy's sharp analysis, which draws on hard numbers from the Department of Energy and other sources, allows us to truly quantify the impact of our everyday habits, and to realize that we're capable of making far more of a difference than many believe.

Last week, Pickens stopped by The Times to discuss his push to wean the U.S. off foreign oil by dramatically ramping up development of its infrastructure for wind and natural gas. Below is a partial transcript. T. Boone Pickens: We are now importing oil that costs us $700 billion a year. That's four and a half times what the Iraq war costs. Nobody running for president even speaks about this. Yet they talk a lot about the Iraq war. When you look at it, the world oil supply is about 85 million barrels of oil a day. And demand is about 86-plus million barrels a day.

The US could replace all its cars and trucks with electric cars powered by wind turbines taking up less than 3 square kilometres - in theory, at least. That's the conclusion of a detailed study ranking 11 types of non-fossil fuels according to their total ecological footprint and their benefit to human health. The study, carried out by Mark Jacobson of the atmosphere and energy programme at Stanford University, found wind power to be by far the most desirable source of energy. Biofuels from corn and plant waste came right at the bottom of the list, along with nuclear power and "clean" coal.

The Scottish Government has created one of the biggest international innovation prizes in history - a £10 million challenge for advances in wave and tidal energy. At a ceremony this week in historic Edinburgh Castle, details of the 'Saltire Prize' were revealed to leading scientists, environmentalists and potential entrants after being finalised by a panel of international experts who comprise the prize Challenge Committee. Dr Anne Glover, Scotland's Chief Scientific Adviser and Chair of the Challenge Committee, said the Saltire Prize will be awarded to the team that can demonstrate in Scottish waters a commercially viable wave or tidal energy technology that achieves a minimum electrical output of 100GWh over a continuous two year period using only the power of the sea and is judged to be the best overall technology after consideration of cost, environmental sustainability and safety.

If you don't already know it by now carbon dioxide is the leading cause of global warming. Since it is the largest factor in global warming it would be prudent for us to eliminate this emission first. Although we can never fully eliminate carbon dioxide, because we and every other air breating creature exhale it, it is possible to reduce it enough to the point it doesn't cause global warming.

Our story of energy begins when humans discovered the secret of fire. We burned wood and brush to protect ourselves from predators, cook food, and, later, to survive the ice age. In 12th-century Europe, with the forests fast disappearing, we started burning the strange black stones we called coal. Later, we used coal to produce steam, launching the Industrial Revolution.

Colorado, United States [RenewableEnergyWorld.com] Vestas held a ground-breaking ceremony this week for its two new manufacturing facilities - a nacelle assembly factory and blade factory - in Brighton, Colorado. The Brighton factories are part of the manufacturing and research base Vestas is establishing in the U.S. His Royal Highness the Crown Prince of Denmark and Her Royal Highness the Crown Princess of Denmark participated at the event. Once the factories are fully operational in 2010, they will create about 1,350 jobs in Brighton. Vestas' investment in Brighton will total about US $300 million, and will secure an annual production capacity of 2,000 blades and 1,400 nacelles.

The Solar Energy Industries Association (SEIA) has released its 2008 U.S. Solar Industry Year in Review, highlighting a third year of record growth for the solar industry. According to the report 1,265 megawatts (MW) of all varieties of solar power were installed in 2008, bringing total U.S. solar power capacity up 17 percent to 8,775 MW. California was the leader among state grid-tied PV installations with 178.6 MW, New Jersey followed with 22.5 MW installed, Colorado was next at 21.6 MW, Nevada installed 13.9 MW and Hawaii with 11.3 MW. The 2008 figure included 342 MW of solar photovoltaic (PV) installations, 139 MWTh (thermal equivalent) of solar water heating, 762 MWTh of pool heating and an estimated 21 MW of solar space heating and cooling.
