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.

With the never-ending supply of renewables, we would feel secure when having abundant supply of energy to last our planet, our human race and our economies, for generations and ever.

Khemani (2011) says: “As long as human life is there, there will be earth, sun, wind and water, and the energy from these sources will also be available as long as they are there”.

According Global Wind Energy Council (GWEC) (2008) reported that turbine installation costs $ 47.5 billion; by contrast, we only have to spend a much smaller amount of money to build thermal power station about $ 2,25 billion (Shah 2011).

He also pointed that other incidental costs such as maintenance costs and production costs cause price increasing.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.Disclaimer: This work has been submitted by a student.This is not an example of the work produced by our Essay Writing Service.Efficient storage media such as batteries and fuel cells are keys for a renewable-powered grid.If battery storage is added to the system, it can supply electricity even after the sun goes down or through several cloudy or stormy days (Pasolini 2012).With the abundance from many renewable resources and development of science and technology, he strongly believes that renewable energy can meet the world’s energy needs today and tomorrow.Besides, one of the greatest alternative energy benefits is that it is so much better for environment than the use of fossil fuels that contribute heavily to issues such as acid rain, smog and global warming.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).
