Renewable Energy

Renewable Energy

sources can be replenished and can be sustained indefinitely. The renewable sources used most often are water (hydropower and tides), biomass (including ethanol, biodiesel, wood, and waste), geothermal, wind, and solar. Development of renewable energy resources can be significantly more costly than other energy resources. Including hydropower, renewable energy accounts for approximately 21% of all global electricity generation; without hydropower, renewable energy accounts for 3.8% of global generation. Wind and solar energy are the fastest growing renewable energy technologies worldwide.
