Brief Definition on What Really is Solar Energy, and its Beginning

Solar Energy is radiant energy that’s produced by sunlight. Everyday sunlight radiates, or emits, a tremendous quantity of energy. The sun’s direct sunlight radiates more energy in one second than people have consumed since the beginning of time!

The energy from the Sun derives from within the sun itself. Like other stars, the sun is a huge ball of gases–primarily hydrogen and helium atoms.
The hydrogen atoms within the sun’s core put together to produce helium and generate energy in the procedure referred to as nuclear fusion.

During nuclear fusion, the sun’s profoundly high-pressure and temperature set off hydrogen atoms to come apart and their nuclei (the middle cores of the atoms) to join or combine. Four hydrogen nuclei fuse to be one helium atom. However the helium atom holds less mass compared to four hydrogen atoms that fused. Some matter is lost through nuclear fusion. The lost matter is released right into space as radiant energy.

It needs countless years for the energy within the sun’s core to make its path to the solar surface area, and then somewhat over 8 minutes to travel the 93 million miles to earth. The solar energy travels towards the earth for a speed of 186000 miles/sec, the speed of the sun’s rays.
Only a small part of the energy radiated from the sun into space strikes the earth’s atmosphere, one part in 2 billion. Still this level of energy is enormous. Every single day enough energy strikes America to provide the nation’s energy needs for one and a half years!

Exactly where does this all energy end up?

Approximately Fifteen percent from the sun’s energy which touches the earth’s atmosphere, is mirrored back in the space. Another 30 percent is used to evaporate water, which, when lifted in the atmosphere, creates rain. The sun’s energy can also be absorbed by plants, the land, and the oceans. The remaining could possibly be utilized to supply our Solar Power needs.
