Britain Breaks in Tidal Power

Ocean

Tidal power isn’t really talked about a lot here in the U.S., but it’s always exciting when a fresh renewable energy technology enters the equation. To wit: Britain just launched a first-of-its-kind contraption that will generate tide power for the Isles. This past weekend, a 122-foot, 1.2 megawatt upside-down-windmill-looking-thing headed out to sea from the [...]

China Wants International Cleantech Fund for Itself

Perhaps China’s been peering over India’s shoulder, watching the deals it’s worked out with Australia to fund its burgeoning cleantech market; and it wants some of the same. Like China, many emerging economies need and want to cut their global warming emissions but don’t have the money to purchase the latest technologies. So China’s come [...]

Does Coal Have a Role in "Clean" Energy?

Coal plants

John Hutton, a business Secretary and cabinet minister in the UK, recently said that coal must remain a part of his nation’s energy system. Although he wants the UK to lead the world in renewable energy, he argues that some form of coal will be needed to work with renewables. The Liberal Democrats, on the [...]

Governors Work on Joint Energy Policy

The National Governors Association (NGA) pretty much agrees that global warming is a problem that needs action, but they’re hardly at a consensus on what to do about it. NGA chairman, Governor Tim Pawlenty (R-MN) launched a year-long initiative called, “Securing a Clean Energy Future,” that outlines how to diversify the U.S.’s energy sources. The [...]

Oil Companies Want Gov't Help for Cleantech

Cambridge Energy Research Associates – called “as close as it gets to a proxy for conventional wisdom within Big Oil” by a Wall Street Journal blogger – just finished a new report that says global warming represents the world’s first serious challenge to the dominance of fossil fuels. Companies know this and are starting to [...]

CFLs in Plain English

I just had two super-efficient compact fluorescent lightbulbs (CFLs) burn out on me, which surprised me since they’re only about a year old. Then again, my husband does leave the bathroom light on a lot…. At any rate, the rest of my bulbs are still going strong, even after several years for most of them. [...]

Raindrops Keep Falling on My PVDF Membrane

French researchers are trying to develop a way to get electricity from rain, claiming the mechanical energy of raindrops could be enough to power low-energy devices. It’s not exactly as sexy as harnessing that big ball of fire in the sky or a towering wind turbine. But a clean, 21st century energy system means trying [...]
