Renewable Energy





Renewable energy is defined as energy derived from natural sources that are replenished at a higher rate than they are consumed, such as sunlight and wind. Unlike fossil fuels, these sources are virtually inexhaustible and produce little to no greenhouse gases or air pollutants during operation, making them key to addressing the climate crisis.
The primary types of renewable energy sources are:Solar Energy: The most abundant energy source, converted into electricity using photovoltaic (PV) panels or mirrors that concentrate solar radiation (solar thermal). The cost of solar panels has plummeted, making it one of the cheapest forms of electricity in many regions.





Wind Energy: Generated by turbines that capture the kinetic energy of moving air. It's a competitive energy source compared to fossil fuels.
Hydropower: Generated by the movement of water from higher to lower elevations, and is currently the largest source of renewable electricity globally.
Geothermal Energy: Uses the Earth's internal heat for heating or electricity generation. It offers a stable and reliable power source.
Biomass (Bioenergy): Derived from organic materials, its sustainability depends on achieving zero-net lifecycle emissions, as burning biomass does produce greenhouse gases.
Ocean Energy: An emerging technology that converts energy from waves and tides into electricity.

Benefits of Renewable Energy


Renewable energy offers significant benefits, including reducing greenhouse gas emissions and air pollution, which is vital for climate change mitigation and public health. It enhances energy security by reducing reliance on imported fuels and stimulates economic growth and job creation. Furthermore, new renewable projects are often the most affordable source of power globally.
