Solar energy is the technology used to harness the sun's energy and make it useable. As of , the technology produced less than one tenth of one percent of global energy demand. Many are. Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.. It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on. Solar power (also knows as solar radiation or insolation) is energy from the sun. This energy, in the form of heat and light, supports all life on Earth, drives the Earth's climate and weather and.

All rights reserved. Solar energy is the technology used to harness the sun's energy and make it useable. As ofthe technology produced less than one tenth of one percent of global energy demand, article on solar energy. Many are familiar with so-called photovoltaic cells, or solar panels, found on things like spacecraft, rooftops, and handheld calculators. The cells are made of semiconductor materials like those found in computer chips.

When sunlight hits the cells, it knocks electrons loose from their atoms. As the electrons flow through the cell, they generate electricity.

On a much larger scale, solar-thermal power plants employ various techniques to concentrate the sun's energy as a heat source. The heat is then used to boil water to drive a steam turbine that generates electricity in much the same fashion as coal and nuclear power plants, supplying electricity for thousands of people. The sun has produced energy for billions of years.

Every hour the sun beams more energy onto Earth than it needs to satisfy global energy needs for an entire year. In one technique, long troughs of U-shaped mirrors focus sunlight on a pipe of oil that runs through the middle.

The hot oil then boils water for electricity generation. Another technique uses moveable mirrors to focus the sun's rays on a collector tower, where a receiver sits, article on solar energy. Molten salt flowing through the receiver is heated to run a generator. Other solar technologies are passive. For example, big windows placed on the sunny side of a building allow sunlight to heat-absorbent materials on the floor and walls.

These surfaces then release the heat at night to keep the building warm. Similarly, absorbent plates on article on solar energy roof can heat liquid in tubes that supply a house with hot water. Solar energy is lauded as an inexhaustible fuel source that is pollution- and often noise-free. The technology is also versatile. For example, solar cells generate energy for far-out places like satellites in Earth orbit and cabins deep in the Rocky Mountains as easily as they can power downtown buildings and futuristic cars.

Solar energy doesn't work at night without a storage device such as a battery, and cloudy weather can make the technology unreliable during article on solar energy day. Solar technologies are also very expensive and require a lot of land area to collect the sun's energy at rates useful to lots of people. Article on solar energy the drawbacks, solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency.

Japan, Germany, and the United States are major markets for solar cells, article on solar energy. With tax incentives, and efficient coordination with energy companiessolar electricity can often pay for itself in five to ten years.

Solar Energy Though costly to implement, solar energy offers a clean, renewable source of power. Article on solar energy by Otis Imboden. Continue Reading.
