Whether we like it or not, cars are not going away anytime soon. In fact, millions are being added to the roads (about 51 million cars were made in 2009 despite the recession), with a lot more to come in the foreseeable future. We, at TreeHugger, try to encourage car-less living as much as possible, but advocating that alone is not enough. In many cases people can't or won't give up their cars, so to make a difference, we need greener car technology that significantly reduces greenhouse gas and smog-forming emissions. Right now, our best bet seems to be electrification (in combination with the cleaning up of the power grid), so this review of 2009 will mostly focus on electric cars.
