Renewable is a term used to describe resources that are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. These energy sources are in contrast to fossil fuels like coal, oil, and natural gas, which are finite and take millions of years to form. The concept of renewable energy is central to discussions about sustainability and mitigating climate change due to its lower environmental impact compared to non-renewable sources.

The utilization of renewable energy has a long history, with wind and solar power being used for centuries in various forms. Modern renewable energy technologies have become increasingly efficient and cost-effective, leading to their widespread adoption. Solar power harnesses energy from sunlight using photovoltaic panels or concentrated solar power systems. Wind power converts the kinetic energy of wind into electricity using wind turbines. Hydropower generates electricity from the movement of water, typically through dams. Geothermal energy taps into the Earth's internal heat. Biomass energy is derived from organic matter.

The transition to renewable energy sources is driven by several factors, including the desire to reduce greenhouse gas emissions, enhance energy security, and create new economic opportunities. While renewable energy offers significant advantages, challenges remain, such as intermittency (the variable availability of some sources like solar and wind) and the need for substantial infrastructure development for widespread deployment.
