Statement For the Problem

The problem right now is that the U.S. is using more nonrenewable energy sources than renewable sources. In the year 2000, 89% of the earth's energy came from the nonrenewable of gas, oil, coal, and nuclear. These sources are non sustainable so over time they will run out along with they add to the changing in the environment. But the problem with the renewable sources is that they do not produce enough energy to support the U.S. demand.
