Stated simply it is a resource which cannot be replenished at a rate equal to or greater than it is consumed. For example, oil is a nonrenewable resource. There is only so much oil in the ground. Every year the world consumes thirtyone billion barrels of oil. At some point, if we continue to use oil at the same rate, we will be using more than we shop for shoes online are extracting from the ground.

On the other hand, if we were able to produce cars that run 100% on solar power, we would be using a renewable resource the sun. It would be renewable because the sun produces so much energy that we would be in no danger of depleting it.

Non renewable energy resources primarily come from fossil fuels. These are fuels that had their genesis millions of years ago as buried organisms decomposed to form the oil, coal, and natural gas that we are able to take advantage of today.

Currently, at least eighty percent of all the energy that we, as a nation, use comes from fossil fuels.

At some point the tipping point will be reached and it will be too late to make effective corrections to the problems that man has caused. No one knows exactly when this tipping point will occur. But nearly all climate scientists agree that it is not that far away. shop for shoes online
