Introduction to Solar Power
Have you ever wondered about the magic behind the solar power? You all have heard about it, and have used it in some way, shape or form, in your life. However, do you know the real mystery behind it? How does it work?
To begin with, solar energy is basically energy from the Sun. Energy collected and used on Earth is known as solar power. On the Sun, nuclear fusion creates energy: nuclei of atoms colliding together. This potential energy, combined with trillions of other atoms travel away from the Sun’s core. Only two-billionth of this potential energy from the sun reaches Earth’s surface. Although this may seem miniscule, it is actually an astonishing amount of energy. This two-billionth of the Energy is so significant that it is capable of meeting all of Earth’s energy needs.
As the energy reaches Earth, it is transformed into many different forms. Oil, gas, coal, and fossil fuel are different kinds of solar energy known as Stored Solar Energy. Although we typically do not think of it as solar energy, it is really solar energy in a different form. However, Stored Solar Energy is non-renewable. This is to say that it can be depleted if humans do not use it at a conservative rate and consume it excessively. That is why engineers across the globe have began to develop alternate energy sources such as nuclear, hydroelectric, wind and geothermal. These technologies have allowed human kind to advance to the state it is today.
It is so crucial for every person to gain an in-depth knowledge of solar power: not just what it is, but also how it works. There is much to develop for solar power as its importance will exponentially grow in the near future. The signs are obvious and are apparent everywhere around us: the growing gas prices, which causes all exports and products we buy to grow in price. For example, we need energy to power transportation, which affects nearly every industry on the planet. We take the energy available to us for granted, and as time goes by the consequences add up, resulting in such issues at crisis levels like global warming.
