The U.S. faces serious energy challenges. With aging nuclear facilities, increased strain on fossil fuel sources and the International Energy Agency projecting a 76 percent increase in energy demand by 2030, renewable-energy sources—such as solar energy—have a big future.
Solar energy also presents serious dilemmas, including high capital costs, broad skill sets required to build photovoltaic (PV) systems and problems created by widespread grid-connected PV systems. However, unlike other energy sources, we won't run out of solar energy any time soon; we just need to learn how to better harness solar resources.
