The Sun, great light on which we all depend. Heat in the cold of winter. Cooked food. The fire of industry, production, the movement of civilization. We are all powered by fire.
Can this be the age of moving from ancient sunlight (fossil fuels) into current sunlight? Only 1 hour of sunlight received by the Earth could power the entire planet for one year . We would only need to cover a land area about the size of Spain to power the entire Earth renewably by 2030.
