Introduction “Sustainable energy” can be considered as the energy that provides for the energy needs of present day without conceding the energy needs of future generations. Sustainable energy sources comprise of both renewable energy sources such as wind & solar energy and non-renewable energy sources such as nuclear energy which could also be utilized as an energy source for generations to come. Sustainable energy plays a vital role in the battle against climate change. It helps to reduce emission of greenhouse gases and carbon footprints. Therefore, it is necessary to adopt the use of existing sustainable energy technologies along with improved energy efficiency and research and investment in new technologies. ‘Green electricity’' means…show more content…
A solar photovoltaic (PV) module works by converting sunlight directly into electricity (even on cloudy days) using semiconductor technology. The vast majority of solar modules available today use ‘waste’ silicon from the computer chip industry as the semiconductor material. They can be integrated into buildings and even made into roof tiles virtually indistinguishable from normal tiles. Solar technologies are characterized as passive solar or active solar depending on the way they are collect solar energy. Active solar technologies include photovoltaic technology and concentrating solar power. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air, solar cooker. Hydro power Water turbines have been used to provide electricity for over 100 years .Although most of the possible sites for large hydropower stations in the here have already been developed, there is a large potential for smaller schemes. These can either use a small dam or work as a 'run of the river' system which has a minimal impact on the local environment. Involvement in process of developing mini hydro power plants are, • Finding suitable locations for potential
