What is the value of a renewable energy source as opposed to nonrenewable?
Nonrenewable is just that, nonrenewable in any reasonable time frame. Therefore, the question is not if, but when we will run out of nonrenewable energy alternatives such as oil, coal and gas. The value to renewable energy sources is that they will not be depleted. For instance, the earth is bombarded daily with sunlight equal to many times the worldwide demand for energy.
