The nation's governors are jumping on the bandwagon of energy efficiency in computing.

The governors of Minnesota and Kansas on Wednesday committed to buying energy-efficient PCs, part of a partnership between the National Governors Assocation and the Climate Savers Computing Initiative.

Launched earlier this year, the Climate Savers Computing Initiative is a group formed by Intel and Google to promote use of energy-efficient power supplies for PCs.

Gov. Tim Pawlenty of Minnesota and Gov. Kathleen Sebelius of Kansas said that new PC purchases for their states will meet the EnergyStar 4.0 rating, which could result in a 50 … Read more

Novomer, a Cornell University spin-off, has devised a method for making biodegradable plastics from the common gases carbon dioxide and carbon monoxide.

The company on Wednesday announced that Physic Ventures and Flagship Ventures have invested $6.6 million, which Novomer will use to commercialize its technology.

The plastics it intends to make could be used in a wide range of applications, including supermarket packaging, computer cases, plastic bottles, or foam to insulate buildings, said Novomer president … Read more

First Solar, those cadmium telluride oddballs, is on the move again.

The company said this week that it has signed a deal to supply Babcock & Brown with solar modules in a deal that will bring it a $1 billion in revenue between 2008 and 2009. Overall, First has contracts to install over 3 gigawatts of power through 2012.

To meet demand for the project, the company's board has approved a fourth manufacturing plant in Malaysia. Two are under construction, and the company announced a third manufacturing plant in April. Each plant will have four manufacturing lines. When up … Read more

Start-up Range Fuels on Tuesday will host a groundbreaking ceremony in Soperton, Ga., where the company will build a plant that will make the fuel ethanol from wood chips.

If successful, the company claims it will be the first to build a commercial cellulosic ethanol plant, using a feedstock that's cleaner than corn--the primary source of ethanol in the U.S. today.

Green tech venture capitalist Vinod Khosla is one the investors in Range Fuels and a high-profile advocate of ethanol and other biofuels.

The numbers behind making ethanol from wood waste, rather than corn, are compelling, he says: … Read more

EEStor: You truly are the company that keeps on giving.

Mort Topfer, the former vice chair of Dell and one of the execs credited in helping turn it from a local phenomenon to a global PC powerhouse, has left the board of EEStor, according to Tyler Hamilton. Hamilton is not the disgraced bike racer but a reporter for the Toronto Star.

It's just one more bit of baffling news out of the Texas-based manufacturer of ultracapacitors, a device that stores electricity, and no doubt another factoid that critics will use to say that the company is not living up … Read more

Marvell has released chips for PC and notebook power bricks that can will substantially cut down the amount of electricity required to run these machines.

The chips, a type of power factor correction (PFC) controller based around a digital signal processor, effectively determine the amount of power an application will need and optimize accordingly. The chips also try to keep peak current at the lowest level.

The chips, which will be included in power supplies, are made to comply with new Energy Star requirements that require that 80 percent or more of the power pumped into PCs actually gets used … Read more

Algae's not the only organism that can be used as a feedstock for biofuel.

BP will collaborate with Arizona State University to try to figure out a way of using cyanobacteria, a photosynthetic form of bacteria, as a feedstock for diesel or synthetic petroleum. Ideally, the bacteria could be cultivated in large, contained plots of land baked by the sun--Arizona has a lot of that. The bacteria also consume carbon dioxide to grow. Thus, carbon dioxide could be pumped in from a power plant into the contained bacteria farm. The company could thus make money from selling carbon credits … Read more

North Carolina's LED Lighting Fixtures has received a $16.5 million injection as the push to bring light-emitting diodes to the home gains momentum.

The company makes light fixtures for commercial buildings and homes around LEDs. LEDs consume far less energy than incandescent bulbs--LED Lighting Fixtures, for instance, sells a lighting unit, the LR6, that puts out 650 lumens but only consumes 12 watts. One or more LEDs can be combined into a single light fixture as well.

Individual LEDs are beginning to challenge compact florescent bulbs in lumens per watt. LEDs also last longer--some go as long as … Read more

Certain biofuels, though eco-friendly, have a reputation for gumming up engine parts, which affect vehicle performance and ultimately reduce engine life. So the idea of a bio-based motor oil makes some of us a little nervous. But one Bay Area-based company is hawking a green, biodegradable motor oil that it says will protect engines as well as name-brand, petroleum-based oil.

G-Oil, made by Green Earth Technologies, is made by converting tallow -- that's saturated cow fat to you and me -- into a high-value unsaturated oil, which is less likely to clog up engine parts. (Tallow was used historically … Read more
