Microsoft says IE10 is more energy efficient than Chrome or Firefox Yes, energy efficient

Ever been concerned about the energy consumption of your web browser? Us neither, but that hasn't stopped Microsoft from ballyhooing that stat to sway you in favor of Internet Explorer. According to the latest tests it commissioned from Fraunhofer USA, IE10 uses up to 18 percent less power in browsing, Flash and HTML5 tasks than its main rivals, Chrome and Firefox. The company claims that translates into more than just boon for your battery life. Redmond goes so far as to say that if every single Chrome and Firefox user switched to IE10, it would save enough energy to power over 10,000 US homes for a year (translation: Google and Mozilla are hurting the Earth). We can't and won't vouch for the authenticity of that statement, but we do know that's a lot of users we're talking about.
