Sources of sustainable electricity 

In today’s time, the focus is on the long-term energy supply adequacy while considering the energy sources’ environmental implications. The most significant advantage of these sustainable sources of energy is their abundance and widespread occurrence. Here are some of the widely used energy sources to produce sustainable electricity: –

Solar energy

Solar energy uses sunlight and photovoltaic cells to produce sustainable electricity. This technology converts sunlight into electricity using semiconductors. Hence, when sunlight hits the semiconductor in a PV cell, the electrons are freed, and busbars collect the running electrons resulting in electric current[1].

International Solar Alliance (ISA) is a dedicated platform through which the global community, including the governments, organizations, and industries, can contribute to help achieve the common objective of maximizing the use and improving the quality of solar energy to meet all the energy needs in a sustainable manner.

Wind energy

Wind energy is one of the fastest-growing sustainable energy technologies. It produces sustainable electricity using the kinetic energy created by rotating turbines. Usage of wind energy to produce electricity has increased significantly in recent years, with thousands of turbines installed around the world, they enable smooth functioning and operational excellence.

According to the International Renewable Energy Agency or IRNEA, the global offshore and onshore wind generation capacity has increased by a factor of 75 in the last two decades. Wind speeds are high in many parts of the world; however, the best wind power generating locations are sometimes remote areas.

Hydroelectricity

Hydroelectric power[2] is harnessed by using the potential of flowing rivers. Hydropower provides sustainable electricity for over 17% of the world, and the primary advantage of these systems is their ability to handle seasonal as well as daily high peak loads. The small-scale hydropower plants under 10 MWe consist of about 12% of world capacity, and most of them are run-of-river ones.

Geothermal energy

Since Earth’s core comprises extremely hot elements, and temperature increases 2.5 to 3.5 degrees Celsius with every 100 meters depth. In the case of geothermal energy, the hot steam underground is tapped and brought to the surface to generate power or sustainable electricity.
