Finally, renewable energy not only is regarded as an unlimited resource but also plays an important role to regional development.

Renewable energy and energy efficiency can help revitalize rural communities (Parker 2010).

The initial costs of renewable energy still make many people ignore it completely when comparing it with fossil fuel on two aspects: total cost and over the same time period.

For example, installation of solar energy water heater costs many times in comparison with a heater, so they decided to buy heaters for hot water solution.

According to Loir, there will probably be sufficient oil and gas for this century, and coal for 2 or more (Loir . Or Edwin Cartlidge reports “the annual total consumption of energy sources by the world population is about 1.4×1017 k Wh, of which the proportion of the fossil energy has accounted for 90% of the energy sources used” (Physics World 7/2007).

Therefore, researchers around the world have been constantly trying to find solutions to diversify energy sources and reduce harmful emissions and greenhouse emissions into the environment and renewable energy sources have taken the spotlight. The Oxford Dictionary (2000) defines renewable energy as natural energy that can be used again and again and will never run out.On the contrary, renewable energy has little or no waste products such as carbon dioxide or other chemical pollutants.Renewable energy systems produce much lower carbon dioxide emissions as opposed to carbon-intensive fossil fuels such as oil, coal and natural gas while they are being used only a small amount of fuel during the manufacturing of equipment (Walser 2012).In some circumstances, renewable energy can be more reliable than other forms of electricity.For example, if the grid gets breakdowns, renewable energy technologies such as generators powered by photovoltaics (PV) can supply electricity automatically.For example, wind turbines or solar panel systems can provide energy and provide rural communities with new tax revenue.Farmers on windy lands can lease space to wind developers, earning thousands of dollars for each turbine every year.Disclaimer: This work has been submitted by a student.This is not an example of the work produced by our Essay Writing Service.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.
