If you want to find waste, you need look no farther than the waste that goes on to bring you your daily dose of 60 cycle 110vac.Fossil fuels must be discovered, extracted, transported, stored, and used to create electricity which must be transported, converted, and finally plugged into your local grid in hopes of you using it at almost the instant it was created lest it be wasted.
Solar power may have many problems which must be solved, but these are solvable problems. The sun is real easy to find almost everywhere, using it is generally pretty clean, it shines for free, and will probably do all these things for millions of years to come. New tech always costs more to start, and, if it's good, the cost drops drastically.
