Renewable Energies BHARC1403 - ICWS Rishabh Bhasin “I declare that this assessment is my own work and that the sources of information and material I have used (including the internet) have been fully identified and properly acknowledged as required in the referencing guidelines provided.” Introduction Renewable sources of energy are the ones that can never be exhausted as they are provided by nature. For example- solar, hydro, wind, biomass. They produce little or no pollution and hence, do not harm the environment. In times of crisis for the world, such as these, everyone is looking to these energy sources. The obvious advantages of renewable energy are that they do little or no harm to the environment. They produce minimal…show more content…
Also, it is not completely green, as some air pollution is produced. The amount of energy also depends on the speed of the wind blowing. So, if the speed of the wind is less, less energy will be produced. Therefore, this form of energy is not suitable for every kind of area. Hydro Energy Similarly, hydropower also has similar advantages. The dams used for creating hydroelectricity also have long lives. In the disadvantages of hydro-energy, dams are extremely expensive to build, and must have high standards. People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydropower schemes can go ahead. (Technologystudent.com, 2015). Building dams can also create natural disasters such as earthquakes. Biomass energy Again, biomass energy creates little emissions and is considered to be a clean energy. When it comes to biomass energy, the main disadvantages are that it does not produce enough energy as compared to fossil fuels. It is harmful to the environment. Using animal and human waste to power engines may save on carbon dioxide emissions, but it increases methane gases, which are also harmful to the Earth’s— ozone layer. (Conserve-Energy-Future, 2013). Meeting the changing demand In times of energy crisis such as these, it is of vital importance that the world falls back
