Energy mission: "Kilowatt Ours"

“What if every time you flipped a light switch, a mountain exploded in West Virginia?”

In the new documentary “Kilowatt Ours,” filmmaker Jeff Barrie explains why that idea isn’t as preposterous as it sounds.

GSA meeting: Biofuels vs. food - developing countries suffer most

HOUSTON – Perhaps it’s because the Geological Society of America’s annual meeting is being held in conjunction with the Soil Science Society of America, the American Society of Agronomy and the Crop Science Society of America, or perhaps it’s because it has been a much-discussed topic this year, but biofuels are big at this meeting.

Bailout bill passes, extends renewable energy tax credits

The new legislation extends the production tax credit for wind energy for one year, and for solar, biomass and hydropower for two years. It also includes tax credits for people who buy plug-in cars and includes an eight-year extension for investment tax credits for people to install small-scale wind equipment or solar energy equipment. As a result, some solar industry stocks are already on the rise.

Unlike the current tax credits, the new bill allows not only residences and businesses, but also utilities to take advantage of the incentives.

Around the world in the Solar Taxi

We can build it. We have the technology.

One thing you can say about the Solar Taxi is that it’s eye-catching. I showed pictures of it from a press conference Wednesday to my co-worker. “Hey, I saw that on the street this morning and wondered what it was,” she says. “That’s the solar car?”

A whale of a wind turbine

According to conventional wisdom, things that need to move efficiently through air or water should be sleek and streamlined. Dolphins, jets and Olympic swimmers stick to this rule, but humpback whales, with their massive knobby-edged flippers, buck the trend.

Dye-ing for efficient solar power

Solar energy is an abundant resource, but so far, solar panels have tended to be relatively expensive and less efficient than desired. Now researchers at MIT in Cambridge, Mass., may have solved both those problems by inventing a new inexpensive dye that works as a “solar concentrator” when painted on ordinary window panes. The dye gathers light energy over the entire surface of the window, then transports it out to the edge of the pane to a line of energy-collecting solar cells.
