What is it?
Solar thermal energy (CSP) is actually very different from this type of solar energy.
How is it renewable energy?
The Sun will never run out of light while humans are on the Earth.
Also harvesting solar energy does not emit greenhouse gases. This is because of the fact that we do not have to burn anything or have anything to do with releasing greenhouse gases with solar energy.
If we harness all of the energy that came from the sun in 24 hours, it would be enough electricity to power the Earth for 1 year!
How much does it cost to install?
Across America, the average solar panel would be $2.87 to $3.85 per watt. For an average American home (5000 watts) it would be $16,800 before tax credits. You get tax credits when installing solar panels. After tax credits, the price will be $10,045 to $13,475.
Now, that may seem like a lot, but when you think about it, it is like an investment. The average electric bill is about $110 a month. That will pay off in about 7 1/2 years because you won't have to pay that.
However, the price of solar panels has dropped significantly. The price in 2013 was 99% lower than it was in 1985, and the price in 2017 was 86% lower than it was in 2013. Economists estimate that by 2022, prices will have dropped another 25%!
Can you get solar energy without installing panels in your home?
Yes! If you do not want to pay the money, you can switch your energy provider to one that uses renewable energy. It will not necessarily be 100% SOLAR energy, but it will be 100% renewable energy. There could also be some wind energy or other types of renewable energy being used. They generate energy using things called solar farms. These solar farms are rows upon rows of solar panels to produce electricity. The image at the top of the page is an example of a solar farm.
