Today’s world is completely dependent on energy. As the demand for energy increases day by day and the conventional energy sources are depleting, there is an immediate need for finding out alternative energy sources. Hence, the contribution of renewable energy sources (RESs) in energy generation over the conventional energy sources has been increasing year by year as shown in Figure 1.1. It is because of the reason that, the RESs are readily available and they are also sustainable. The energy from these sources is converted into a usable form and utilized for domestic as well as industrial applications. The renewable energies such as solar, wind, biomass, geothermal, hydro, and ocean energy can be converted into more useful energy like electricity. They deliver power with minimal impact on the environment. These sources are typically more green/cleaner than conventional energies like oil or coal. Among all the RESs, solar and wind energy plays a significant role in electric power generation [1]. They can supply power to either gird or isolated AC or DC loads [2]. Hydro energy is the next most used source for electricity generation. Geothermal energy which is produced from the heat of the earth’s crust can also be used for energy conversion. Here, the thermal energy from the inner surface of the earth is converted into electricity. Tidal energy is also effectively utilized nowadays as low tide and high tide plays a vital role in producing electrical energy. All these RESs are discussed in detail in the following sections.
