RENEWABLE ENERGY SOURCE Meaning and
Definition
-
A renewable energy source refers to any naturally occurring and replenishable resource that can be converted into usable energy. It is a type of energy that can be continually and indefinitely replenished or replaced by natural processes within a relatively short period of time, unlike non-renewable resources such as fossil fuels. Renewable energy sources are considered sustainable and environmentally friendly, as they do not contribute significantly to pollution or greenhouse gas emissions.
Examples of renewable energy sources include solar power, wind power, hydropower, geothermal energy, and biomass. Solar power harnesses the energy from the sun by converting sunlight into electricity through the use of photovoltaic cells or concentrated solar power systems. Wind power utilizes wind turbines to generate electricity by harnessing the kinetic energy of the wind. Hydropower is generated by converting the gravitational force of water into electricity through the use of dams or tidal turbines. Geothermal energy utilizes heat energy from beneath the Earth's surface to generate power. Biomass refers to organic matter, such as plant materials or animal waste, that can be burned or naturally decomposed to produce heat or converted into biofuels.
The utilization of renewable energy sources is crucial for reducing dependence on non-renewable resources, mitigating climate change, and achieving sustainable development goals. It offers the potential to meet the increasing energy demands of society while minimizing the negative environmental impacts associated with traditional energy sources.
