Solar Power Essay example -- science

solar Power every(prenominal) life on state depends on naught from the sunniness. Solar energy is the source of energy for photosynthesis. It provides the warmth required for plants and animals to survive. The heat from the sun causes water on the Earths surface to evaporate and form clouds that eventually provide fresh rainwater. Solar energy is the result of thermonuclear optical fusion reactions deep within the sun. These reactions produce so much energy that they keep the surface temperature of the sun at close 10,300B0F. Even though solar energy is the largest source of energy received by the Earth, its intensity at the Earths surface is actually very low due to the large distance between the Earth and the sun and the fact that the Earths atmosphere absorbs and scatters some(prenominal) of the radiation. Even on a clear day with the sun directly overhead, the energy that reaches the Earths surface is reduced about 30 percent by the atmosphere. When the sun is near the hor izon and the sky is overcast, the solar energy at ground level can be negligible. It overly varies from one point to another on the Earths surface. Nevertheless, in the 20th century, the suns energy has become an increasingly attractive source for small amounts of direct power to get together human needs. A number of devices for lay in solar energy and converting it into electricity have been developed, and solar energy is used in a variety of ways. Solar energy is used to heat houses, and in many countries specially designed solar... Solar Power Essay example -- scienceSolar PowerAll life on Earth depends on energy from the sun.
