How it Works Solar Energy- power from the sun- it is a vast and inexhaustible resource. Solar energy supports all life on Earth and is most important for almost every form of energy we use. Heat from the sun causes temperature differences between areas. Solar energy is passed through to the earth in certain portions of energy called photons, which interact with the earth’s atmosphere and surface.
Uses Solar energy is important for saving the environment. It is the most easy and used and most convenient of the renewable energy sources. (Including wind and water) Solar energy has been used since the beginning of time as a heating source. One of the other solar energy platforms was developed as a solar energy cooker and it was used on a safari In the 1830’s. Since the 1970’s many people have been putting solar collectors on their roofs and using the resulting collected power for usage in their houses. You use solar power to heat your hot water.
Disadvantages It does not work at night. It is very expensive to build solar power stations. The cost has been lowering as technology improves. Over all solar cells cost a lot compared to the amount of electricity that they’ll produce in their lifetime. You can not really count on it unless you’re in a very sunny climate. In the United Kingdom, solar power isn’t really used for high- power applications, you really need a huge area of solar panels to get a good amount of power. Technology has improved to the point where it can make a big difference to home fuel bills.
Dangers Generated by nuclear fusion within the sun. This process goes on the same basic laws of nuclear physics used in nuclear power plants and atomic bombs. The source of this energy is hydrogen, a highly explosive ga.
Cost Solar energy has many different costs depending on the size of where you live, the amount of electricity you use and the particular solar energy system you choose. A solar hot water system will cost between two thousand dollars and four thousand dollars. A photovoltaic system will cost between eight thousand dollars and ten thousand dollars.
Technology uses in New Jersey New Jersey has one of the fastest growing market for solar photovoltaic's. It is one of the largest states in terms of installations.
Where solar energy is used Use in residential homes to heat water. Panels Power plants
Big plan in New Jersey The plan is to develop the largest solar farm on the East Coast on approximately 512 acres of farmland.
Pollution Solar Energy is Pollution Free Kind of weak because it needs to pass first through the atmosphere which protects the Earth from the sun’s intensity
Conclusion Solar energy is an easy source of energy that is renewable to harness for home use. It is the energy force that holds onto life on the earth for all plants, animals and people.
