Wave and tidal energy
Tidal power has potential for future electricity generation, since tides are more predictable than e.g. wind and solar power
The world’s first large-scale tidal power plant is the Rance Tidal Power Station in France. The newer Sihwa Lake Tidal Power Station is bigger. New forms of tidal power plants are being built, and new technologies continuosly tried out.
Waves can give an endless and strong supply of energy with the right technology.
Geothermal energy exploits the heat in the interior of the Earth for heating buildings and producing electricity. Geothermal energy is environmentally friendly, as it produces no waste. It has become increasingly popular in apartment buildings.
Hydrogen is high in energy, yet an engine that burns pure hydrogen produces almost no pollution. NASA has used liquid hydrogen since the 1970s to propel the space shuttle and other rockets into orbit. Hydrogen fuel cells power the shuttle’s electrical systems, producing a clean byproduct – pure water, which the crew drinks.
A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a chemical reaction into usable electric power. However, the fuel cell will produce electricity as long as fuel (hydrogen) is supplied, never losing its charge.
