Abstract:

The global water demand is increasing constantly due to growing populations, which now account for 16.5% of all countries. Fossil fuel-derived electricity, which is used to pump this water, extends the pump’s life cycle and increases greenhouse gas emissions. As power electronics and drives have advanced, renewable energy sources like the sun and wind can now be used to generate electricity for water pumping, minimizing greenhouse gas emissions. This study proposes the use of renewable energy sources, such as solar and wind energy, to generate electricity to pump water underground to meet energy requirements without producing greenhouse gases. Photovoltaic cells receive energy from sunlight, which is then used to pump water. However, because sunlight is a natural resource, there are times when conditions like climate change or seasonal concerns like the rainy season prevent the solar panel from producing enough power to pump the entire amount of water. Similarly, wind turbines generate wind energy based on wind velocity, which can become insufficient at times due to climate challenges. Thus, the two types of energy sources are combined to provide a sufficient amount of power, and a hybrid system that utilizes both solar and wind energy to pump water is used. If however the energy generated by both sources is greater than or equal to what is needed, storage batteries are used to store the excess energy and supply.
