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.

Shoes are outer coverings for the foot. They have soles， and most have heels. The upper part of most shoes extend no higher than the ankle. Boots are footwear that reach beyond the ankle. People wear shoes to protect their feet from harsh weather， sharp objects， and uncomfortable surfaces. Shoes are also an important part of people"s clothing. As a result， fashion often determines the style. of shoes that individuals wear. The desire to be fashionable has led to many unusual shoe styles. In the 1300"s，many European men wore shoes called crackowes， which had an extremely long toe. From the 1300"s to the 1700"s， some European women wore shoes with really thick soles causing walking to be virtually impossible without support. Shoes once worn in the Orient were connected to a stilt（高跷） as high as six inches.

Traditionally， most shoes are made of leather. But many other materials are now used. Including canvas， velvet， and synthetic substances such as plastics. Footwear materials and style. vary somewhat，depending on climate， custom， or other differences. Farmers in Netherlands often wear heavy wooden shoes that protect their feet from the damp environment while Japanese wear shoes outside their home but prefer soft slippers at home. In fact， people in some regions often wear foot coverings other than shoes. Some wear sandals during the hot summer and switch to warm boots for the cold winter.
