(I don't consider burning hydrocarbons to be a useful way to use sunlight, because of the by-products.) The Sun lavishes something like 10,000 times more energy on Earth than the entirety of the energy used by human civilisation, I believe? Certainly a lot more than we need, even if you knock off the amount used for keeping warm and so on (most of it goes back into space anyway, I think). -- You received this message because you are subscribed to the Google Groups "Everything List" group.
