It is easy to overlook that most of the energy we consume daily, such as electricity or natural gas, is produced with the help of a dwindling resource - fresh water. Virginia Tech professor Tamim Younos and undergraduate student Rachelle Hill are researching the water-efficiency of some of the most common energy sources and power generating methods.
After months of intense effort to secure renewal of tax credits and other incentives which have helped spur record growth in the use of renewable energy, solar and wind power companies were rewarded when the U.S. Senate passed The Clean Energy Tax Stimulus Act of 2008 with strong bi-partisan support in an 88 to 8 vote.
enXco, EDF Energies Nouvelles' US subsidiary, has obtained a permit from the authorities of the Solano County, California, to build a 150 MW wind farm. This new large-scale wind farm, owned by enXco, will strengthen EDF Energies Nouvelles Group's already strong presence in California.
"Energy efficiency, diversity - including technology - and new sources of domestic supply are vital to sound U.S. climate policy. Congress must include domestic energy supply in any climate bill."
Today, President Bush announced a new national goal to stop the growth in U.S. greenhouse gas emissions by 2025. This new goal marks a major step forward in America's ongoing efforts to address climate change.
In a world with increasing pressure to protect the environment - from the ozone layer to the whales - it would seem reasonable to assume that American families actively support "green" initiatives in their consumer habits.
AAER Inc., Canada's only original equipment manufacturer of wind turbines of 1 megawatt ("MW") and more, announced today that Wind-Smart LLC, a subsidiary of AAER USA, has signed an agreement for the delivery of its first 1.5 MW wind turbine in the U.S. to the Town of Portsmouth, Rhode Island.
Given the global consensus on climate change, world leadership has looked at growth in India and China with increasing alarm. The prior experience of industrially-developing countries worldwide would suggest that as an economy grows, it consumes more and more energy. Given currently available energy and technology options, this in turn leads to increased carbon emissions into the environment.
The American Fan Company will keep your house cool as it gives a wind chill factor of up to 5 degrees C. It is the environmentally-friendly option, as it only uses 5% of the power required for an air conditioning unit - the fan uses about the same electricity as a 100 watt light bulb compared to the 2,000 to 3,000 watts required for an equivalent air conditioning unit.
Wind provided more electricity than several other alternative energy sources in 2007 -- approximately 1 percent of the global supply. By 2020, experts predict that wind will generate about 12 percent of world electricity needs, but the reliability of generating equipment is essential to the success of the rapidly growing wind power industry.
