Solar Energy Introduction With the unlimited energy we receive from the sun‚ solar energy has the capabilities to meet the endless demand of energy and electricity both here in the United States and worldwide. Solar Energy is the one of a few energy sources that emits no carbon dioxide into the atmosphere at all. When comparing the cost and benefits of solar energy to other energy sources it is clear that solar energy is the most viable form of energy possible. With renewable energy becoming

Solar Energy The Sun is a star and without it there would be no life on earth. This is why the Sun is called the ultimate source of energy. The Sun’s energy is produced by a process called nuclear fusion. Every second‚ the Sun emits vast amounts of energy‚ much of which is light‚ and this solar radiation can be converted into electricity. Plants and trees are pretty good at collecting this energy. With the help of green chlorophyll‚ they use light energy to make food – they’re our solar powered

Characteristics A solar panel is a collection of many small solar cells spread over a large area. These solar cells work together to provide sufficient energy to power a given item. (Northwestern University) Their creation is a very delicate process which is why many of their advancements did not come until last quarter of the 20th century. In this period‚ advancements in semiconductors and photovoltaic products allowed efficient and cost effective solar panels to be produced. (Solar Panel Info)
