The renewable technologies of today are in their infancy. If serious effort is put into developing all the range of ways of harvesting and using the energy all around us supplied by the sun - solar, wind, wave, water - and the others from the earth itself and the moon - tidal, thermal - we will have more than would know what to do with it.

Nuclear power is a short-term fix, with consequences our descendants will have to cope with for thousands of years, and with such a long lead in before it can be available that the tehnology will probably be completely outdated, and very possibly never used.
