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.

While much attention on renewables in recent years has focussed on solar and wind technologies, awareness has been growing around the enormous energy generating potential of the Earth's oceans. A 2005 report from the Electric Power Research Institute stated that wave power properly and effectively harnessed, would likely have minimal environmental impact, and be much less visible on the landscape, than competing technologies. At the same time, waves possess the advantage of being more predictable than either wind or solar, which in principle makes ocean power a more reliable source of energy.

2009 brings some new incentives for homeowners to adopt energy efficiency from both state and federal sources. The Wall Street Journal reported last week on several of these, including new provisions for tax credits in solar, small wind, and biomass stoves (those burning wood pellets or corn). In addition, this year, both solar and wind residential tax credits can be claimed against the alternative minimum tax. Improvements to weatherize your home could also qualify for an energy efficiency tax credit of up to $500. There are also new credits for upgrading your furnace, boilers, heat pumps, and water heaters. Read more at WSJ.com: http://tinyurl.com/93n535 Link to original post

Spanish wind power companies in the world's third-largest producer expect steady growth in capacity this year despite the credit crunch due to long-term investments, an industry spokesman said on Monday. Wind power business group AEE tallied 16,740 megawatts in installed capacity in Spain at the end of 2008, a rise of 1,609 MW for the year. "We expect a similar amount (of growth) this year," AEE president Jose Donoso said at a news conference.

Duke Energy announced that it will expand its renewable power business with the development of a second wind energy project in Cheyenne, Wyoming. The company also announced that it has signed a power purchase agreement for the project and has secured turbines.

China is planning a stimulus package worth 440 billion dollars to expand its renewable energy use, state media said, as the country aims to rely more on cleaner ways to power its growth. The three trillion yuan (439.7 billion dollars) investment will see part of the focus on wind power, the Beijing Morning Post said, citing Liang Zhipeng, a State Energy Administration official. The government has collected opinions from local economic planning agencies and relevant companies about a draft plan, Liang said, according to the report. Under the plan, China's wind power capacity will reach over 100 gigawatts by 2020, the report said, more than triple a goal of 30 gigawatts announced in 2007 in a renewable energy development plan.

New York City, United States [RenewableEnergyWorld.com] Close to US $155 billion was invested in 2008 in renewable energy companies and projects worldwide, not including large hydro. Of this $13.5 billion of new private investment went into companies developing and scaling-up new technologies alongside $117 billion of investment in renewable energy projects from geothermal and wind to solar and biofuels. The 2008 investment is more than a four-fold increase since 2004 according to Global Trends in Sustainable Energy Investment 2009, prepared for the UN Environment Programme's (UNEP) Sustainable Energy Finance Initiative by global information provider New Energy Finance. Of the $155 billion, $105 billion was spent directly developing 40 GW of power generating capacity from wind, solar, small-hydro, biomass and geothermal sources. A further $35 billion was spent on developing 25 GW of large hydropower, according to the report.

The ocean harbors abundant energy in the form of wind, waves and sun. All of these could be sampled on something called an Energy Island: a floating rig that drills for renewables instead of petroleum.

A New Jersey company said on Tuesday it will invest $20 million over three years to develop an underground compressed-air storage system for wind turbines and other power sources, a sign of growing confidence in the technology. Energy Storage and Power is a joint ventured formed by energy developer PSEG Global and Michael Nakhamkin, who designed the only compressed air-storage facility in the U.S.

This is a DOE report on Europe's community based model for developing wind energy.

One in four British homes could be fitted with solar heating equipment and 3,500 wind turbines could be erected across Britain within 12 years as part of a green energy revolution to be proposed by the government next week.

A new lobbying firm for the group opposing a wind farm off Cape Cod filed a federal document last month reporting that its work for the Alliance to Protect Nantucket Sound is partially funded and shaped by an international energy conglomerate.

For students from Hocking College's alternative energy and vehicular hybrids program spending the quarter on the Andros Island in the Bahamas was no spring break. Applying what they have learned about wind, solar thermal, solar PV and micro-hydro power systems, their goal was to make the village of Forfar totally self-sustainable.

April 29 (Bloomberg) -- Billionaire energy investor Boone Pickens, founder and chairman of BP Capital LLC, speaks at the Milken Institute Global Conference in Los Angeles about the outlook for oil, U.S. energy policy, and alternative energy including wind and solar power.

T. Boone Pickens is a billionaire oil man and a career corporate raider who loves George Bush so much he donated $250,000 to his 2004 inaugural ball. He was, and still is, fully behind the invasion and occupation of Iraq and makes no bones about it. So why is he now pushing for the use of alternative energy sources like wind and solar in his Pickens Plan?

In South Korea, wind power would be a likely resource to help the world's tenth largest energy consumer meet government goals to lower fossil fuel dependency through greater investment in renewable energy.

Last night was the tenth time since June 2007 that an extension of wind and solar tax credits have gone to the floor of the Senate. Seven times they have been stuck in bills that have gone to the floor of the House of Representatives. And they're still not law.

Abu Dhabi has taken a 20% stake in the London Array - the £3bn project to build the world's largest offshore wind farm in the Thames estuary. Masdar, part of Abu Dhabi's multibillion-pound drive to develop green energy technologies, is buying part of the 50% stake in the project held by the German-based utility E.ON.

According to a Stanford University researcher, 'wind, water and sun beat biofuels, nuclear and coal for clean energy.' The scientist 'has conducted the first quantitative, scientific evaluation of the proposed, major, energy-related solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability and sustainability.' Wow! The researcher found that some sources of energy were 25 to 1,000 times more polluting than the best available options. Some of his conclusions make sense, some are controversial, but read more…

The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford. And "clean coal," which involves capturing carbon emissions and sequestering them in the earth, is not clean at all, he asserts.
