We are like tenant farmers chopping the fence around our house for fuel when we should be using Natures inexhaustible sources of energy - sun, wind and tide ... I'd put my money on the sun and solar energy. What a source of power! I hope we do not have to wait until oil and coal before we tackle that run - Thomas Alva Edison
What he was for a progressive scientist! Sunrise and sunset are certainly one of the most beautiful scenes you have ever seen with your beautiful eyes, and I bet you'll never get bored as they get this over and over again every day at dusk. The sun is now about beauty, because the scientists to create the invisible sunlight a reliable alternative source of energy "solar energy" to humanity exploited to serve and give them a better world to live in.
"Green World" is now a buzzword in today's world. We are now very concerned about our future. Renewable energy such as solar energy, hydropower, wind power, geothermal, biomass, tidal and God gifted resources and the use of them, we can lead to a green world.
For a layman, solar energy can be referred to as "Solar energy is the energy of the sun in the form of light is produced." But if you want to get in deeper, then to better understand the explanation would be - "There is a continuous reaction goes in the sun, this process is called fusion (joining of two small atoms to make a big atom) in the sun two hydrogen atoms together and makes a new helium atom, but while converting the weight of helium is found slightly smaller than the hydrogen that is lost matter the energy that comes to Earth by electromagnetic wave, and we call all There sunlight. "According to scientists, every second 600 million tons of hydrogen is converted to helium and 89000 terawatt power finally comes to the surface. This is 59000 times more than our consumption of 15 terawatt. So, that's all we need to do to use this radiation energy as much as possible.
The best known way to make use of this energy as far as the photovoltaic (PV) cells is. The science behind the phenomenon of the use of electricity from sunlight is called the photoelectric effect, which was discovered in 1839 by a French physicist named Edmond Becquerel, later Sir Albert Einstein received the Nobel Prize for explanation of the photoelectric effect in 1905. In fact photoelectric effect is not a hard concept to understand. Material such as silicone is the photoelectric effect. When sunlight hitting the surface of a photonic solar cell that is specially treated silicone made, the electrons are released from silicone, this is the photoelectric effect, and we all know that electricity is nothing but a flow of electrons.
Some PV cells PV module. The first photovoltaic module was invented by Bell Laboratories (Lucent's current name) in 1954, but it was too expensive to use on a large scale because they had poor efficiency. MIT conducted research on solar energy in the 1930s, 40s and 50s and it was commercially successful. Later spacecraft uses solar energy, it improves the technology and finally we now have 100 times less cost than in the 1970s.
Today solar power is very popular all over the world. It is considered a likely solution for the green world. You could also participate in the campaign use of solar energy. We should all be nice to the planet earth as much as possible....
Thank you for coming in Energy Efficiency Reviews and read the article about: Introduction of Solar Energy , help us to Shared this article. hopefully useful to us all.
