Bobbing for Energy in the Pacific Northwest
December 17, 2007 4:50 am | CommentsEnergy News: Most of Earth's surface is covered with free, green, non-depleting energy -- the movement of ocean waves -- and scientists say that power could be a major contributor to electric grids if only it were easily captured. So, researchers at universities such as Oregon State, and at start-ups such as Finavera Renewables and Ocean Power Technologies, are experimenting with special buoys that transfer movement into energy.

At the University of Minnesota, they're figuring out how to make algae grow very fast, and how to get up to 15,000 gallons of oil per acre -- that is 750 percent more yield than
Get Your Low-Energy Computing with a Catch
November 27, 2007 11:21 am | CommentsEnergy News: Three stories about energy efficiency, focusing on computers, landed in my inbox today -- with a big fat asterisk attached. The stories are: Google Plans Renewable Energy Push -- they want to make one a gigawatt of clean energy cheaper to produce than the same amount of coal; HP Enters Two Renewable-Energy Contracts -- they're using solar and wind power for facilities in San Diego and Ireland; and Climate Savers Computing Initiative Empowers Smarter Computing Choices -- there's an online catalog of green desktops and servers, but it's only for companies that pay to join
