How does solar energy work? is it feasible to our modern world?
Question:
Answer:
There's solar energy as most people think about it, converting the energy in sunlight into electricity. Some new cells treat the light as radio waves (which it is, but very, very high frequency) and use tiny "antennas" to convert it to electricity. These may make solar power more practical.
Other types of "indirect" solar power include wind (which the sun drives) and hydroelectric which works because the sun evaporates water which then falls as rain in higher locations. The water running downhill can be made to drive turbines and create electricity.
Solar energy is the result of a reaction in the sun known as Nuclear Fusion. In the elctromagnetic spectrum solar energy possesses both light and heat. Heat is converted into mechanical energy which is then used for performing work.
In today's world, solar energy will be of prime importance when fossil fuels are on the verge of extinction.Already this source of energy is in use although in minute proportions. If man is able to utilise this energy proprely then it will be of great use to mankind.
