Google has just launched a Web page detailing its annual energy use and carbon footprint impact.
It argues that to provide a user with Google products for a month–not just search, but Google+, Gmail, YouTube and everything else it offers – its servers use less energy per user than a light left on for three hours. And, because it says that it’s been a carbon-neutral company since 2007, “even that small amount of energy is offset completely, so the carbon footprint of your life on Google is zero.”
