Solar Power is a semi Eco-friendly way to produce energy through the sun. It is used in most countries around the world today. Solar energy uses solar panels that help turn heat waves into electricity.

__**How does it work?**__ Solar Power works because of solar panels. Solar Panels work because they are coated with a thin layer of silicon. Also it has solar cells that help catch heat waves and move electrons through the wires creating electricity. Photovoltaic cells and photoelectric cells help transform sun light into electricity.The solar modules catch the sunlight then Photovoltaic cells help transform them into solar cells and this is the outline. A more clearer explanation would be only that there is a coat of Silicon only on the surface of the panel (That's why the solar panel becomes blue) not inside the panel. Silicon is a manufactured substance whose crystalline structure makes good semi-conductors. The interesting thing about making a solar panel is that you never use pure silicon, because scientist found out that pure silicon does not work as good on solar panels. So the silicon is manufactured to be imperfect which creates a more dynamic effect and also lasts longer than pure silicon. What happens inside the solar panel is that the electrons are knocked out of place by the photon ray from the sun, which in turn creates a cause. The photon makes the electrons float around. Electric fields that are created by the silicon cause all the electron to move in the same direction creating electric energy, into your house heating water and others.

__**How widespread is it?**__ Right now in our world Solar Power makes up 0.05% of the "World's" energy. (Keep in mind that I said world and not country). Solar power is the most used in Germany. In 2009 Germany installed 3806 megawatts, otherwise known as MW. The country that uses solar power as much as Germany is Spain. Spain installed 2605 MW in 2008. Next is Japan, it is believed that Japan will reach it's goal is 2020, their goal of using 2800 MW. Other countries that solar power is wide spread in is U.S., Italy, Czech Republic, Belgium, China, France, and India Even with all these countries using Solar power it still only creates 0.05% of the world energy.

__**Benefits and Drawbacks**__ Solar Power has many benefits as well as disadvantages __**Benefits:**__
 * It can be reused
 * Sun Energy is free
 * It takes it's energy from the sun
 * It has batteries to store the energy from the sun
 * Needs no maintenance at all
 * It is always changing to better and more ridiculous products

__**Drawbacks:**__
 * It's definitely useless without the sun
 * It costs a-lot of money to make solar panels(even though the price is decreasing)
 * Depends on the weather
 * Causes pollution when made
 * Not everyone can get solar power or panels

__**How Efficient is it?**__

Solar power is quite efficient, but it depends on the size of the solar panel and how bight the sun is on that day. For example you will need about 41000 square inches of Solar Panel to power up a house that would be most efficient for the house. The simple concept is that the bigger the panel the more and longer energy and electricity it will create. The smaller the panel the less and shorter energy and electricity it will create. Solar Panels last about 25-30 years.

**__Role in the Future__** In our opinion, we think that Solar Power would be more used in the future. But at the same time it would deteriorate our planet even more, because to make a Solar Panel you would need to coat it with a layer of [|Silicon]. Also because of how much fossil fuels are being used. Right now fossil fuel is the most used in the world. While fossil fuel is being used, it is a kind of source that would run out eventually. But there’s also the other reason, from our observance, we have found out that the cost of Solar Panels has been decreasing over the years. Plus the new products that happen to use solar power, which also help in our opinion is becoming very popular, such as the “ Solar Backpack ” that can charge anything from a Laptop to a Digital Camera.
