Many of the problems we face today are not so new as we think they are. And some of our modern solutions are not so new, either. The problem of energy shortages and the solution of using solar energy go back at least to early Greek cultures. The climate in the coastal areas of Greece 2,500 years ago was characterized by cool winters, much as it is today. At that time, the Greeks heated their homes with small, charcoal-burning heaters. In other words, wood(which is used to make charcoal)was their primary source of energy. However, by the fifth century BC fuel shortages had become common because, in many parts of Greece, the firewood in the forests had been
depleted
. Once the supply of firewood from the local forests ran out, people began to use the wood from olive groves as fuel. But this solution had its own problem. It reduced the olive crop, a valuable resource to the Greeks. By the fourth century BC, the city of Athens banned the use of olive wood for fuel. Wood had to be imported from farther and farther away, making it more difficult to obtain and more expensive to use. About this time the Greeks began to build their houses facing south, so that the low sun in winter could penetrate and help heat the interiors. Excavations of ancient Greek cities suggest that large areas were planned so that individual homes could take maximum advantage of passive solar energy.
