Question

Write short note on
Electrical energy generation and environment.

Answer 1

Today electrical energy generation has become the need of the hour. We cannot imagine our life without electricity. We have been able to generate electrical energy by various methods. In these methods, a generator is present which works on the principle of electromagnetic induction. A turbine is used to rotate this generator and this turbine itself is rotated with the help of an energy source. This energy source can be renewable source such as wind, sunlight, nuclear fuels etc. as well as non-renewable source such as coal, petrol, water etc. The energy sources such as wind, sunlight have proved to be green sources as they do not pollute the environment and are economical too. But the use of fossil fuel such as natural gas, coal, nuclear energy etc. as energy source has harmful effects on environment. The harmful radiations emitted from the nuclear waste has fatal effect on the environment and humans. Even the release of soot particles and various greenhouse gases such as carbon dioxide, carbon monoxide on burning or incomplete burning of fossil fuels affects the health of living beings as well as the environment adversely. Also, the release of these greenhouse gases is day by day increasing the danger of global warming. We need to as soon as possible find suitable environment friendly substitutes to fossil fuels to save our Earth.
