Who doesn't love jumping in the car for a road trip to a Star Trek convention?! Well, people who don't like Star Trek, but you can replace that with any of your favorite geeky things. Thanks to tech that is greener, we don't have to put as much in our gas tank to make our nerd pilgrimages. Smaller devices being more energy-efficient is also good because, well, the planet doesn't explode. We don't want to live through our favorite post-apocalyptic fiction, so here's to green technology!
