This story is not new. Today, solar energy is picking up momentum. But despite the current numbers and the recent raves, the solar saga, and that of renewable energy as a whole, has been going on for decades. It is a history of false starts and stutter steps.

First, the good news. According to the Solar Energy Industries Association (SEIA), 2011 showed record-breaking numbers for U.S. solar installations. The industry's best year ever saw demand rise by 109 percent over the previous year. With tremendous incentives and benefits for homeowners, and as prices continue to decline, the future looks bright for this alternative energy source.
