Solar energy is an attractive form of renewable energy. It is "free", doesn't produce any carbon dioxide, and doesn't require large scale machinery. The energy it produces (electricity) can be used immediately or can be stored in batteries. It can even be "stored" in the grid which has the happy result of making your energy meter run backwards (you are selling your excess power to the electric company). So why haven't we converted everything to solar?
