Tools for change are everywhere: help yourself. WorldChanging lifts the veil from hidden opportunities for smarter living that are all around us. The site has a lovely consistency of tone, and talks about smart products, ideas, trends, and sustainable conveniences. And all of it is ingeniously organized by the scale of change you feel you're up to from "Stuff" and "Shelter" to "Community" and "Cities," up to and including the "Planet" itself. Choose your own adventure.

Since commercial and industrial buildings represent around 40 percent of U.S. energy use, and homes another 30 percent, this represents the most significant opportunity for energy efficiency and mass-scale renewable generation.
