= = == Geothermal Energy! Geothermal is heat in the Earth. ** We can use this heat in buildings. ** The word geothermal comes from the Greeks. Geo means earth and thermal means heat. __  ............................................... .......................................................................................__  == == ** Renewable and Non Renewable energy! Renewable energy means energy that can be reproduced. Non Renewable energy is energy that can be only used once. Renewable:** Biomass, Hydro, Solar, Wind. **Non renewable: Coal,oil, gas ** == == ** __     ...........................................................................................................................................................................__ ** == = Solar It's a fact that all life comes from the Sun. The production of oxygen will be impossible without solar energy. Today less than 0.1% of our heating transportation and power energy comes from direct sunlight. __   ..............................................................................................................................................__ = = Hydro Energy Hydro Energy is electricity made by water. When water flows or fall, energy can be generated. The generation of energy though water is usually carried out in large water plants with a series of steps and many devices such as turbines and generated the energy in water to make electricity. Hydro energy is clean. __ . ........................................................................................................................................................................ __ Energy Energy is the ability of any object to work. **Some forms:** Electric, Thermal, Chemical, Solar and many more. Most objects have energy. Two main energy are Kinetic and Potential. __  ............................................................................................................................................................................... __ = = Wind Wind turbines do not produce lots of wind power so they need to be planted in very large amounts. Windmills have been around for centuries, mainly to pump water. Today some scientist are testing huge wind generator designed to provide power on a large scale. most of the new wind machines don't remotely resemble the traditional windmill although all of them have blades or routers of some kind. =
