Renewable Energy Sources - INI

Renewable energy sources refer to energy sources that are continuously replenished by natural processes, including solar, wind, hydropower, geothermal, biomass, wave, and ocean thermal energy conversion (OTEC). Unlike fossil fuels, they do not deplete and emit minimal greenhouse gases during power generation, making them crucial for both climate change mitigation and energy security. According to the International Renewable Energy Agency (IRENA), solar photovoltaic power is expected to meet approximately half of the world's new electricity demand in 2025, establishing renewable energy as the core of global power supply.
