Solar Power Essay example -- science

solar Power all(prenominal) life on ground depends on zilch from the solarise. solar heftiness is the tooth root of vital force for photosynthesis. It provides the warmth necessary for plants and animals to survive. The groove from the sunniness causes peeing on the Earths surface to evaporate and form clouds that in conclusion provide raw rainwater. Solar postcode is the result of thermonuclear partnership reactions deep in spite of appearance the sun. These reactions produce so much energy that they nurture the surface temperature of the sun at about 10,300B0F. tied(p) 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 blank between the Earth and the sun and the fact that the Earths atmosphere absorbs and scatters some 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 atm osphere. When the sun is near the prospect and the sky is overcast, the solar energy at undercoat level peck be negligible. It also varies from one point to other on the Earths surface. Nevertheless, in the 20th century, the suns energy has become an increasingly attractive source for humble amounts of direct power to meet human needs. A number of devices for compendium solar energy and converting it into electricity have been developed, and solar energy is apply in a variety of ways. Solar energy is used to conflagrate houses, and in many countries specially designed solar... Solar Power Essay example -- scienceSolar PowerAll life on Earth depends on energy from the sun. Solar energy is the source of energy for photosynthesis. It provides the warmth necessary 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 thermonuc lear fusion reactions deep within the sun. These reactions produce so much energy that they keep the surface temperature of the sun at about 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 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 horizon and the sky is overcast, the solar energy at ground level can be negligible. It also 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 meet human needs. A number of devices for collecting solar energy and converting it into electricity have been develope d, and solar energy is used in a variety of ways. Solar energy is used to heat houses, and in many countries specially designed solar...
