Honeywell has developed a computer program that provides customers with the data they need to choose the best renewable energy for their needs. The Renewable Energy Scorecard analyzes the variables of any location in North America.

It's a growing energy trend in the U.S.: Proposed coal plants denied because they fail to address or sufficiently limit the amount of carbon dioxide. Georgia is the latest state to rule on this.

Wal-Mart just announced that it's selected capitol buildings in 19 states and Puerto Rico to assist with cutting emissions and save on energy costs. The company will actually pay engineers to do the energy audits and for the capitols. Whoa.

New hybrid vehicle registrations went up 38 percent in 2007 and are expected to keep growing this year. Here's why.

Minnesota beat out 16 other states to land the International Renewable Energy Technology Institute (IRETI). IRETI will be a collaboration bewteen Minnesota, New York, Georgia and Sweden to exchange renewable energy technology.

An eight-turbine wind farm will open in Panhandle, Texas in May. But instead of referring to it as "that Panhandle wind farm," it will be have a branded, corporate name: "The Wege Wind Energy Farm, provided by Steelcase."

An organization of energy experts finds that building more green buildings is the best way to cut CO2. In fact, green buildings could cut emissions more deeply, quickly and more cheaply than any other global warming mitigation effort.

This is exciting stuff: Xcel Energy is going to test 80-ton batteries the size of two semi-trailers to capture the power generated from its wind turbines.

Saudi Arabia makes more than 10 million barrels of oil a day, but it may be turning an eye on a cleaner prospect: solar power. Is this an attempt to be a big player in the solar energy field - or is the Saudi government concerned about global warming?

A study examines the four most common types of photovoltaic (PV) solar power cells - multicrystalline silicon, monocrystalline silicon, ribbon silicon and thin-film - to find out how much energy and waste are involved in their creation.
