At last night's Republican debate, Michelle Bachmann tried to stake Tim Pawlenty on his support for cap-and-trade. The EPA wised up and banned DuPont from selling Imprelis, the herbicide that was killing trees. San Francisco could require businesses to let bikers bring their ride inside.
The climate skeptics can finally get excited about the 2012 election: Texas Gov. Rick Perry, their candidate of choice, is about to officially throw his hat in the ring.
An Energy Department panel wants to require natural gas companies to disclose what chemicals they're using in hydrofracking projects. Green groups have an idea for how to cut the country's debt: stop subsidies to oil and gas companies. But (of course!) most of the members of the Super Congress are opposed to regulating greenhouse-gas emissions.
Wind turbines are loners. They need to give each other space to be effective. But a new design for wind farms, using a different type of turbines than the giant-fan kind going up all over the place, takes a page from a very social group of animals -- schooling fish -- to create the same amount of energy with shorter turbines, in a smaller area of land. These wind farms use vertical-axis turbines, which are often described as looking like egg-beaters.
Wind power is pretty bad-ass to begin with, but conventional wisdom is that it's a "mature" technology that, unlike solar and other breakthrough energy technologies, won't be seeing much improvement in the coming decades. WRONGITY WRONG WRONG.
Sometimes even Al Gore can’t resist cursing when he talks about climate skeptics. Listen here. EPA's scientific integrity policy doesn't do a particularly good job at its intended purpose: protecting scientists from political influence. Heavy-duty trucks have to meet fuel efficiency standards too. No word yet on monster trucks.
Wind turbines are becoming bigger, more efficient, and more powerful. Drilling in the Arctic is not such a hot idea, as any spill will be tricky to clean up. The Southeast is the only region in the country that hasn’t put renewable energy mandates in place.
Not satisfied with making (more of) a mockery of the electoral process, Donald Trump is now going after wind power, vowing to use "any legal means" to block a planned windfarm near his golf course …
Wind power's not entirely safe: A watchdog group warns that "one of these days, a turbine's going to fall on someone.” The U.S. gets a C for renewable energy development from an alternative energy analyst. Colorado's going to require fracking companies to disclose what's in their fracking fluid. The natural gas boom is also creating demand for silica sand.
