| The oceans with their tides offer a seemingly unlimited supply of renewable energy. For two decades, tidal stream technologies power over 1700 homes in Scotland. Although there are technical problems, tidal energy could well supplement wind energy, since it is very consistent. related: #tidal_energy #renewable_energy |
