I think we should use the wind, sea and sunshine. They are all free, all we need is the technology to harness these natural resources.
It annoys me when people object to wind farms because it would spoil the scenery! Surely with the problems we have with oil spills and the mess mining makes of the world, a few beautiful wind turbines are not going to spoil anything!
The oil will run out eventually, but the wind, sun and surf will always be here.
