Solar – Energy by the sun
Solar energy is the energy which is generated by the sun’s rays. This happens through nuclear fusion processes in the inside of the sun whose radiation partly reaches the earth’s surface.
Solar energy is consideredthe safest source of energy. Sincethe sun produces limitless energy and is hardly exhaustible, it is considered the largest available source of energy of humanity.
The sun is about 150 million kilometres away and 109 times larger than the earth. It consists of 70% hydrogen, 28% helium and 2% other metals. The process of changing hydrogen to helium inside the sun, known as sun’s rays, hits the earth in the form of electromagnetic waves. By the time the sunbeams finally hit the earth, eight minutes have passed.The potential of the sun’s rays is so enormous that people’s energy needs can be covered 10,000 times only by the sun’s rays of the solar systems.
There are various ways of using them in the solar energy sector . Solar power plants, for example, combine light radiation with an absorber that generates extremely high temperatures. The heat is then converted into electricity in a downstream thermal power plant. This offers for example, private households, the opportunity of capturing the sun rays
through collectors that are used for heating or generating hot water. Advantages of Solar Energy summarized
- No emissions in power generation
- Is available in unlimited form
- No disposal of waste necessary
- No loss of energy due to transport, since it is produced wherever it is used
- Stable price level due to low dependence
