You don't have to rewire your home or set up massive photovoltaic solar panels to step off the grid. Visit the U.S. Department of Energy's Web site to find out if your utility company allows you to purchase clean energy from low-impact sources such as wind, solar, hydroelectric, and geothermal power.
Harnessing the power of these renewable "fuels" will enable us to reduce our dependence on coal-burning power plants, a major source of greenhouse-gas emissions and pollution, while helping shift the economics and production of clean energy in a positive direction.
