Solar Energy

this week i had term paper and i chose to write about fossil energy and how it can be replaced by another source of energy like solar energy and by that i knew too many things. fossil fuel and natural resources that we count on to produce all kind of energy can be finished so we have to think about another way generate power and energy or find another source. most of the natural sources are going to last for 50 to 100 years except United States that has backup sources for 200 to 250 years from now. the best way to replace anykind of energy is by the solar energy because we are sure that ther will be sun everyday no matter what even with cloudy and stormy days but the sun is always going to be there, so we have to act smart and start taking advantage of the sun as long as its free ....who knows maybe later or after many years from now we will have to pay for it?????????? not too many people are familiar with this system or maybe they are just trying to ingnore it now because it is expensive and we still enough oil and gas resources but we have to think about the next and after next generations.
