Photovoltaic Industry Roadmap (Roadmap for building a $15 Billion solar–electric industry.)
US Department of Energy (DOE) web site.
DOE’s Office of Energy Efficiency and Renewable Energy (EERE) web site.
The EERE’s web site has a lot of interesting information related to renewable energy. In particular here is their main page on Photovoltaics which will lead you to all sorts of information such as Why PV is Important where one encounters statements such as “Few power-generation technologies have as little impact on the environment as photovoltaics.” and “Let’s take a look at the many ways PV is bettering our world-today.”
