Tweet-a-Watt is taking the trophy here. There are hacks to make things efficient, to run them on renewable energy, to make them accomplish green tasks. But one thing we love is the spark of competition to get more efficient. Tweet-a-Watt is riding the wave of the social media phenomenon and the rising awareness of efficiency among a demographic that can make the biggest difference when they adjust their habits. Those are some magic ingredients, and makes this DIY hack a winner.–J.H
