passed, and Microsoft reckoned it had better things to do, but Zuckerberg's Castle is seemingly willing to pick up where those two left off. In what may go down as the strangest Facebook decision since the rejection of Valentina Monetta's video as best in the whole wide world, the company is launching a new social energy app that'll tap into technology from the National Resources Defense Council and Opower. Initially, the app will reach some 20 million households, and it's designed to help eco-curious Earthlings compile and benchmark usage data to see how their home stacks up against others. Within territories with utility participation, people can connect their utility account directly to the app to track progress and share energy saving accomplishments with friends. Unfortunately, the whole process looks rather manual for now, and privacy overlords will no doubt question the motives for requesting even more information from Facebook users; that said, it's totally possible to engage in the Opower tracking sans a Facebook account. To get going, give those source links a look.
