All About: Solar Energy

[CNN]  The sun, we are frequently told, is the best source of energy there is—so much so that in just one hour it can provide the earth with all the energy its inhabitants demand in a year. Not only can the sun provide us with all of our energy needs (10,000 times over in fact, according to Greenpeace) but it can also apparently do this without any of those unpleasant side effects that you get from fossil fuels such as air pollution or ozone depletion. And best of all, this resource will never run out—or at least, not in the next 5 billion years or so.
