Renewable energy is energy that is derived from natural sources that are replenished at a higher rate than they are consumed[1]. Examples of renewable energy sources include solar energy, wind power, hydropower, geothermal energy, tidal power, and biofuels. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. There are also emerging technologies in the field of renewable energy, such as enhanced geothermal systems, marine energy, and artificial photosynthesis
