Solar_Energy

Solar Energy Solar energy originates from the Sun. It is created by nuclear fusion reactions that occur in the Sun’s core. It can be used to generate electricity, provide hot water, and to heat, cool, and light buildings. It is the most important and vital factor of life, because any substantial change in its radiation power would alter or end life on Earth. The Earth naturally collects solar energy in oceans, plant life, and in the atmosphere. Humans can use this to influence technology. A direct way of obtaining solar energy is by two different kinds of artificial collectors. These are called flat plate collectors and concentrating collectors. The former are thin boxes with a see-through cover, which are placed of the top of roofs and facing the sun. These are used for water and space heating. Concentrating collectors are more expensive and complicated; therefore, they are more beneficial for uses such as air conditioning and central power generation. The temperatures they can acquire are higher than that of flat plate collectors. Solar energy falls on buildings and is used to heat them without special devices.
