Sources such the sun and the wind, can never be exhausted and for that reason called renewable. They cause fewer emissions are available locally. Their use can, with a large extent, reduce chemical, radioactive and thermal pollution. They're a viable supply of clean and limitless energy. These are the non-conventional sources of energy. Most of the renewable sources of energy are fairly non-polluting and considered clean with the exception of biomass, a renewable source, is really a major polluter indoors.<br /> <br /> Sources of renewable energy or non-conventional energy are the sun, wind, agricultural residue, firewood and animal dung. Energy generated from the sun is known as solar energy. Energy derived from water is known as hydroelectricity. Biomass is firewood, animal dung, biodegradable waste from cities and crop residue. It becomes a source of energy if it is burnt. Geothermal energy is energy produced from hot, dry rocks, magma, warm water springs and natural geysers. Ocean thermal is energy derived from waves and tidal waves.<br /> <br /> [http://www.renewableenergytechinfo.com Solar Power]<br /> <br /> When it comes to renewable energy, the most powerful and useful is the sun. The sun is available from sunrise to sunset and produces an unimaginable amount of energy each and everyday. What solar collectors do is always to harness the energy from your sun in the form of radiation to be usable forms of energy including heat and electricity, Solar cells in particular converts the sun's energy into electricity. With technology being so advanced, solar cells are taken to a fresh level. There are motorhomes, cell phones and cars.<br /> <br /> Solar Heat<br /> <br /> Solar heating systems rely on a source of bright light, a surface or liquid that may absorb light plus a storage device for the resulting heat generated. A greenhouse is a great one of this effect. Solar heat is definitely the cheapest and most practical kind of renewable energy in the world. Some practical uses are hot water heaters, ovens, cookers and warming.<br /> <br /> [http://www.renewableenergytechinfo.com Green Living] - Wind Energy<br /> <br /> From times long, way back when, sailing ships been dependent on the energy of the wind to get across oceans. Likewise wind energy was also used to work windmills for pumping water. Today, wind power will be used as a clean electric source around the world. Wind farms, as they are often called can provide enough electricity for thousands of homes at a time. The effectiveness of wind is used to show turbines, which in turn is attached to an electrical generator and also the gearbox inside the generator converts the energy of the spinning turbine into electricity.<br /> <br /> Water Power<br /> <br /> Hundreds of years ago, waterwheels were used to offer power for grain mills and lumber cutting. Hydroelectricity, because it is called today, produces over 60% of the electricity in Canada and 60% in the United States.</div> Mon, 23 Apr 2012 15:43:21 GMT BackusCarmen879 http://beta.aalf.org/wiki/index.php?title=Talk:BackusCarmen879
