Seems like every time we turn around, the Department of Energy is making another announcement about our nation's energy future (if you believe that most cars will eventually be electric, these announcements are about our automotive future as well). Just a few days ago, we told you about the DOE's promising investment of $62 million into concentrating solar technology. Good news. Then we told you about the DOE's request for commentary on squeezing the last precious drops of fossil fuels from the

Tapping some of the enormous amounts of thermal energy that emanates from deep within the earth is one of the more promising methods of renewable power. Unlike wind and solar, geothermal tends to be a lot more consistent than the sun or flow of air. It now looks like geothermal power could have another potential benefit: waste water from at least one geothermal plant in central California is rich in lithium.

In order for electric vehicles to make any actual impact on greenhouse gas emissions, a great deal of progress will need to be made on renewable sources of power generation. Wind power generation has been expanding rapidly, and solar is growing in some areas. Another source with huge potential is geothermal. If the natural heat energy held within the planet can be tapped, it could be almost limitless. That's easier said than done in most places but there are some areas where it could be very pra

Since Iceland is so geographically remote and lacking in a lot of natural resources they have been looking for ways to harness the power they do have. Two things that Iceland does have in abundance are ice and geothermal energy. Iceland has been making a major push into using hydrogen as a fuel and producing it locally with the heat energy from within the earth.

In a lengthy, two-part editorial, David Roberts, a staff writer at Grist, presents his position on unifying the green lobby around the flag of URGE2: Use Renewably Generated Electricity, Efficiently. He is expecting bumper stickers and t-shirts - here's why.

Bloomberg compares in a lengthy article the current boom in venture capital funding for alternative energy companies with what we saw during the dot-com boom. Many of the venture capitalist firms in California are dangling millions of dollars in front of solar panel makers and biofuel companies, which are often money-losing companies hoping to harness the power of the sun or cooking up gasoline and diesel substitutes from a variety of crops. VC funds investments in renewable energy rose 36 perce
