Renewable energy

Renewable energies (hydropower, solar, wind, geothermal, and biomass) are developing rapidly around the world, driven by the need to combat global warming by reducing greenhouse gas emissions.

Provided by the sun, wind, the earth’s heat, waterfalls, tides, and even plant growth, renewable energies generate little or no waste or polluting emissions. They help combat the greenhouse effect and CO2 emissions into the atmosphere, facilitate the sustainable management of local resources, and generate jobs. Solar (photovoltaic solar, solar thermal), hydroelectricity, wind power, biomass, and geothermal energy are inexhaustible energy sources compared to “stock energy” derived from fossil fuel deposits that are becoming increasingly scarce: oil, coal, lignite, and natural gas.
