Non-renewable

ENERGY: Renewable vs Non-renewable

Non-renewable sources of energy

Nonrenewable sources of energy have continued to produce constant energy throughout the world. This is because of their high availability. Sources of nonrenewable energy can be attributed to natural sources that are not regenerated once the source is depleted. Sources include fossils fuels such as coal and petroleum products e.g. natural gas and diesels.

Pros of non-renewable sources of energy

Some such as natural gas burns without any soot hence less environmental pollution.

1.     Most nonrenewable sources of energy are easy to transport from one area to another. For example petroleum oils which can be transported via pipes.

2.     Cost of producing nonrenewable energy is low since they are naturally available. Furthermore they are cheap to transform from one form of energy to another.

3.     Most of this energy sources are abundantly available in different areas. Their availability is not affected by climatic condition.

Cons of non-renewable sources of energy

1.     Produce harmful green house gases which contribute global warming. Coal once burnt produces carbon dioxide harmful to the environment.

2.     Once they are depleted they cannot be replaced making them expensive to obtain.
