When seated by the window of a bus on a sunny winter day, you may feel very warm. These {{U}} {{U}} 1 {{/U}} {{/U}}occur because solar energy is present. Solar energy is energy given off by the sun. Imagine gasoline flowing over Niagara Falls at the same {{U}} {{U}} 2 {{/U}} {{/U}}the water does. That would be 5 billion gallons of gasoline an hour! Suppose that all the flowing gasoline is collected for over 200 million years. If that gasoline is burned {{U}} {{U}} 3 {{/U}} {{/U}}, it would equal the amount of energy transmitted by the sun in one hour. Not all the solar energy released by the sun {{U}} {{U}} 4 {{/U}} {{/U}}the earth's surface. About 34% is scattered into space by the gases or dust in the atmosphere. Another i9% is {{U}} {{U}} 5 {{/U}} {{/U}}by the different layers of the atmosphere. The {{U}} {{U}} 6 {{/U}} {{/U}}47% finally reaches the ground where it is absorbed as heat.

For years, solar energy has been used to evaporate water in making dried foods. During the mid-1970s, shortages of oil and natural gas occurred in the United States. These shortages created a need to develop solar energy into a {{U}} {{U}} 9 {{/U}} {{/U}}source of energy to heat homes. Solar energy can be used both to heat and to cool the inside of buildings; it is used to heat water in homes and swimming pools. The main power supply for spacecraft is batteries that change solar energy to electrical energy. One way to get energy directly from sunlight is by the greenhouse {{U}} {{U}} 10 {{/U}} {{/U}}. A greenhouse has glass walls and a glass roof. Sunlight passes through the glass to heat the air inside. The heated air cannot move out through the glass, so much of the heat is trapped inside.
