Perspective Shift: Greener Cars From TreeHugger

This week at TreeHugger: If Google is trying to rule the world, it's looking pretty good to us. Among its many ambitions, the web master is pursuing plans to bring clean plug-in hybrids to the streets. The Lightning electric road-missile is looking to give the Tesla a run for its money. London, already spoiled with multiple green taxi services, now has another. Great, jolly good for them. But at least here in the States, Hertz has added more than 3,000 new hybrids to its rental lineup. California passed a resolution to blend all the state's gasoline with 10% ethanol. A recycling monster-machine that claims to turn car debris into oil and gas and cut landfill waste by 65%. Our bullshit radar is buzzing, but could it be real? And speaking of bullshit patrol, Exxon Mobile tries to say it never doubted the risks of climate change. Meanwhile, at a conference, the oil giant proposes a new feedstock to meet world's oil needs: dead humans.
