Renewable Energy - Page 21

Renewable energy refers to energy that is generated from natural resources that are replenished on a human timescale. These resources include sunlight, wind, rain, tides, waves, geothermal heat, and biomass. Unlike fossil fuels, which are depleted when used, renewable energy sources are sustainable and have a much lower environmental impact.The main types of renewable energy include solar energy (harvesting sunlight), wind energy (using wind turbines), hydroelectric energy (from flowing water), geothermal energy (from heat stored beneath the Earth’s surface), and biomass energy (from organic materials). The utilization of renewable energy is essential for reducing greenhouse gas emissions, combating climate change, and promoting energy security. It plays a critical role in the transition to a sustainable energy system, aiming to provide clean, affordable, and accessible energy to meet global needs.
