Renewable electricity is electrical energy generated from renewable and sustainable energy sources. These sources naturally replenish and hold a notably lower environmental impact than traditional non-renewable sources such as coal, oil, or natural gas. Resources generating renewable electricity remain virtually inexhaustible and do not deplete over time. Utilizing these resources helps to reduce carbon emissions, mitigate climate change, and decrease reliance on finite and environmentally damaging energy sources.
Key sources of renewable electricity include:
Solar Energy: Electricity generated from sunlight using photovoltaic (PV) panels or concentrating solar power (CSP) systems.
Wind Energy: Electricity generated from the kinetic energy of wind using wind turbines to drive generators.
Hydroelectric Energy: Electricity generated from the gravitational force of falling or flowing water. It involves the use of dams, rivers, and other waterways to turn turbines and produce electricity.
Biomass: Electricity generated from organic materials, such as wood, agricultural residues, or organic waste, through combustion or conversion processes.
Geothermal Energy: Electricity generated from the Earth's internal heat. Geothermal power plants use steam or hot water extracted from underground to power turbines and generate electricity.
The adoption and expansion of these technologies are key components of the transition towards a more sustainable and environmentally friendly energy system.
