What is a “renewable energy source”?
Renewable energy sources are wind, solar and geothermal power – these are all considered renewable energy sources. Hydro is certainly considered a renewable energy source as well. Large hydro has great costs; smaller hydro is preferable. They’re all renewable energy sources by nature of the fact they can be replenished. They will not run out on you as quickly as fossil fuels, for instance, that take millions of years to create. All energy is solar energy; it all comes from the sun, and it’s stored. Fossil fuels were created during the Carboniferous period and stored as coal and crude oil. So wonderful, let’s use it up, and Ed just said it’s all solar energy — let’s use solar energy in the form of crude oil. Great, you can do that, but there’s a price to be paid for using all that up that quickly, and this energy is not reneweable. The price is air pollution, the price is unstable regimes in the Middle East and elsewhere and the price is certainly running out of this wonderful non-rene
A renewable energy source is, in essence, an energy source that can be renewed. Basically, it won’t run out like a fossil fuel eventually will (like petroleum/oil). A few examples of renewable energy sources would be wind, solar energy, water and/or hydrogen, and even geothermal energy (the Earth’s internal heat)!You can find more information here: http://www.nrel.gov/learning/re_basics.h…
