Alternative energy sources are growing. In 2008, for the first time, worldwide investment in alternative energy sources drew more investors than fossil fuels, netting $155 billion in net capital inflows against $110 billion of new investment in oil, natural gas and coal. This is helping to drive the price down for alternative energy systems.

Wind power has traditionally been the largest driving force in alternative energy in the United States. Systems can be constructed quickly, but are notoriously expensive. Solar on the other hand is getting cheaper. Some analysts are predicting solar photovoltaic prices could fall as much as 43 percent this year.

As more and more homeowners, commercial property owners, and Power Companies add Solar technologies, prices will continue to fall, and the technology will get even better.
