Renewable energy comes from natural resources like sunlight, wind, rain, tides, and geothermal heat. About 16% of global energy comes from renewables, with 10% from biomass mostly for heating and 3.4% from hydroelectricity. New renewables like small hydro, modern biomass, wind, solar, and geothermal make up another 2.8% and are growing rapidly. Renewable energy has advantages like being sustainable long-term and emitting no greenhouse gases or toxic waste, but also has disadvantages such as having a limited total potential and currently high capital costs for equipment to convert it.
