Here' a list of top 10 lessons for going green, based on the world's biggest company's surprising efforts to become more sustainable. It's from my new book, Force of Nature, just up at HuffingtonPost:
Forget all that scary stuff you've heard from politicians about how cutting carbon emissions to stem climate change will kill jobs and destroy American business. Wal-Mart says that's crazy talk. Greening your home or business makes your richer. How? Carbon comes from using energy. Energy costs money. Which means cutting carbon saves the planet and saves you money. So do what Wal-Mart does: use energy-efficient lighting. Plant shady trees near your house or business. Insulate your attic and, if you have a flat roof, paint it white. Clean the filters in your refrigerator, heater and AC. Small businesses who follow Wal-Mart's advice have had their energy bills drop 20 to 60 percent by taking just those steps.
