Abstract
Energy derived from renewable resources, and which are replenished inside the human common lifestyles scale, inclusive of sunlight, wind, rain, tides, waves and geothermal heat, is called renewable strength. About 19% of worldwide very last strength intake got here from renewable, with 13% coming from conventional biomass, and 3.2% from hydroelectricity. The percentage of renewable power technology is round 18%, 15% of worldwide power coming from hydroelectricity. Earlier evaluation of destiny strength pathways indicates that it's miles technically viable to reap progressed strength access, air great and strength safety concurrently even as keeping off risky weather change. Economic growth, automation and modernization especially relies upon the safety of strength supply. Global strength call for is rapidly growing and presently the global situation is on a way to satisfy the destiny strength call for. The air and water pollutants emitted through coal and herbal fueloline plant life are related to respiratory problems, neurological harm and coronary heart attack. Renewable strength regularly gives strength in hydro, biomass, solar, smart grid.

Key words: Renewable energy, Resources, Solar energy, Smart grid, Wind energy.
