As renewable or no renewable

Explanation:

The natural resources are classified as renewable or no renewable. The renewable natural resources are the ones that are constantly present, caused by the nature, and they can not be spent. Some of these natural resources are the wind, and the sunlight. The no renewable resources are the ones that are in limited amounts, thus they can be spent. Some of these natural resources are the oil, natural gas, and coal. The no renewable natural resources though are much more used than the renewable ones. The reason for this is that tend to produce more energy, and also are relatively cheap. The renewable natural resources are on the rise when it comes to their usage, and lot of nations make a lot of effort to make them their primary source of energy, but it seems that that will take a while.
