Recently, the concern for alternative sources of energy that can be renewed and their use being environmental friendly have increased greatly. The search for sustainable renewable energy has drawn global attention. 

The need for renewable energy was triggered as the current sources of energy, coal and oil are not renewable, thereby resulting in depletion of these sources. Also, pollution results from the extraction and use of these energy sources. It is a well known fact that as human beings, we depend greatly on energy. Everything we need to do today depends on energy which coal and oil have been our major sources of energy.   Hence, there is need for a green and renewable source of energy.

It is very important to discuss a State that has really been running on and enjoying the potentials of renewable energy - Massachusetts. Massachusetts is a State in the United State of America that has been making use of Wind and Solar energy. In fact, the Government is planning that the state runs completely on renewable energy. Due to the ecological and geographical advantages the state has, it has been exploring the potentials of wind and solar energy. However, despite the potentials of wind energy  in the sate, its dependence on solar energy is greater. 

This is due to the limitations of wind energy. These limitations therefore have revealed the advantages of Solar energy over wind energy as listed below.

1. Wind energy depends greatly on geographical and ecological location of the area. Wind energy is best used in coastal regions, offshore areas and ridge crests in mountains.

2. Wind Energy lacks constancy in its power generation. Unlike, solar energy, it does not generate certain amount of energy, making it erratic.

3. From literature review, it has been discovered that energy produced from solar panels is more than the produced from wind turbines.

Researches and implementation of alternative sources of energy such as Bio-mass, Geothermal, Wind, Solar etc., have been carried out. Currently, solar energy has been the most used source of renewable energy. However, while there are ongoing researches on other sources, wind, geothermal energy sources have been implemented.
