That California and Texas still lead the United States in generating renewable energy probably is no surprise. But, NREL's 2009 State of the States report shows that several smaller states from Maine to Louisiana to Utah are closing the clean energy gap, confirming that every state has...
Norway opened on Tuesday the world's first osmotic power plant, which produces emissions-free electricity by mixing fresh water and sea water through a special membrane. State-owned utility Statkraft's prototype plant, which for now will produce a tiny 2-4 kilowatts of power or enough to run a coffee machine, will enable Statkraft to test and develop the technology needed to drive down production costs.
It's nearly Thanksgiving, the second of the "big" holidays that break up the last three months of the year. One of the most common family traditions is listing the things for which we are thankful. These are mostly items such as "family," "friends" or "good
Last week, the Environmental Protection Agency announced its new green homes Web site. The site provides an interactive experience that helps people
This week, John discussed buying clean electricity from your utility. If you can't set up a small renewable energy system of your own, buying clean electricity is a great way to support the use of renewable energy.
The exterior skin of NREL's newest building will do more than keep the weather out. The concrete panels actually will be part of the Research Support Facilities' heating and cooling system. It's an old idea brought back to life in the name of energy efficiency.

Back in March, we reported on the California Energy Commission’s proposal to set a cap on the maximum active mode power usage (watts) for TV’s. All units above the maximum would be banned for sale in California—this would preclude the vast majority of Plasma, DLP, and Rear-projection TV’s.
Earlier, we reported that global investments in renewable energy had dipped 40% from 2008-09—thus, the following comes as welcome news. George Soros has decided to invest $1 billion of his own money into “green technologies.” Soros issued a clear directive on how his money ought to be spent
