Homes, such as the two shown here, can use an occasional breeze to supplement their electricity needs. In consistently windy areas, small windmills can supply all of a home's energy and even a little extra, which is often sold back to the utility companies. The American Wind Energy Association ranked Michigan 14th in the nation for wind energy potential.

Geothermal Heat Pump Pipes

Geothermal heat pumps use the Earth's natural capacity to absorb and release heat to cool and heat a home. The system circulates a fluid through a system of pipes in the ground to either absorb heat from or release heat to the Earth. These systems are quieter and smaller than conventional units (i.e. gas or electric). They use almost 50% less electricity than conventional units and require no fuel to operate. Also, geothermal steam is used by two Western states to generate electricity.
