No surprises here.

White House officials last December sought to stop the Environmental
Protection Agency from submitting a proposed rule that would limit
greenhouse-gas emissions from new vehicles.

The proposed rule was EPA's response to an April 2007 Supreme Court
ruling that the agency had violated the Clean Air Act by refusing to
take up the issue of regulating automobile emissions that contribute to
global warming. » read more

A
Canadian engineer has a plan to extract
energy from a man-made tornado.  It all depends on heating the air near the surface so that it is much warmer than the air above.

Convective air currents are only useful if they can be
channeled in some way. » read more

You just can't win.

Researchers are developing new technology that  uses nano-technology to drastically increase the lifespan of batteries.

The key innovation involves using silicon nanowires instead of the usual carbon to store energy in a lithium-ion battery's anode.  Silicon has more than 10 times as much charge capacity as carbon. With this innovation, you could theoretically be running your laptop for 20 to 40 hours straight rather than the typical two to four hours. An electric car could go 400 miles on a charge rather than 40 miles. » read more

I was just reading about how there is a big push for environment awareness at this year's Sundance Film Festival.
