Solar energy facts that would make you believe in its potential

A lot of countries across the world have started utilising the solar energy but there are many who have yet not exploited the power of sun to meet their everyday energy needs. Here are some solar energy facts that would make you believe in its potential in meeting global energy requirements.

The sun is located at a distance of 90 million miles from the earth. But it takes less than 10 minutes for the light to travel back to the earth.

The earth receives 174 Petawatts of incoming solar radiation in the upper atmosphere. Only 30% of solar radiation is reflected back to space. Rest all is absorbed by oceans, clouds and land masses.

Solar power is one of the most exciting uses of solar energy. The process involves conversion of solar energy into electricity by using either photo-voltaic or concentrated solar power. Photo-voltaic uses photoelectric effect to convert solar energy into electric energy. In case of concentrated solar power, large beams of sunlight are focussed into a small beam using mirrors or lenses.

Solar energy is considered as the future of alternative energy source since it is not polluting and helps combat the greenhouse effect.

Solar energy causes no pollution, doesn’t have any environmental effects, and is ecologically friendly.
Solar energy is one of the most widely used renewable source of energy in the world. With the help of renewable energy techniques and methods, solar energy is being converted to electricity.

If there is battery back-up, solar energycan provide electricity 24 hours a day and 7 days a week, even on cloudy days and during night when there is no sun.
