Microsoft says IE10 owns the coveted 'most energy efficient browser' title

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 10. 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. While claiming that's a boon to laptop battery life, Redmond went so far as to say that if every single Chrome and Firefox user would just switch to IE10, it would save enough energy to power over 10,000 US homes for a year. We can't vouch for the authenticity of that stat, but we can say that as of late, that's a lot of users.
