Fossil fuels are, essentially, stored solar energy. What we are basically doing now, by burning fossil fuels, is recycling a small proportion of the extra CO2 that was in the earth's atmosphere during the Carboniferous Era. In Britain, before the start of the industrial revolution, the forests were becoming depleted through over-exploitation.
