Similarly, wind power energy relies on moving air and converts it into electricity without polluting the environment.

Therefore, it is obvious that the non-pollution or minimal impacts on environment are the positive advantages of renewable energy.

Although it is obvious to recognize the human as well as environmental advantages of utilizing renewable forms of energy, we must also consider some limiting sides from the energy.

The biggest disadvantage of renewable energy is that the cost of the energy is relatively higher than non-renewable energy.Together with the rapid growth of the world population, the limited ability to supply of non-renewable leads to energy demand on a rise especially in developing countries.This situation results in the risk of depletion of cheap fossil energy and environmental pollution as well as climate change.Disclaimer: This work has been submitted by a student.This is not an example of the work produced by our Essay Writing Service.The use of renewable energy has many potential benefits, including human beings and environment.Firstly, renewable is one of the most important advantages of renewable energy.According to Loir, there will probably be sufficient oil and gas for this century, and coal for 2 or more (Loir .
