Renewable Energy is energy based on resources that are regenerative or all practical purposes cannot be depleted. Sources such sunlight and the wind, can't ever be exhausted and so called renewable. They cause fewer emissions and are available locally. Their use can, with a large extent, reduce chemical, radioactive and thermal pollution. They may be a viable way to obtain clean and limitless energy. These are the non-conventional sources of energy. The majority of the renewable sources of energy are fairly non-polluting and considered clean aside from biomass, a renewable source, can be a major polluter indoors.
Sources of renewable energy or non-conventional energy will be the sun, wind, agricultural residue, firewood and animal dung. Energy generated from your sun is known as solar power. Energy derived from water is named hydroelectricity. Biomass is firewood, animal dung, biodegradable waste from cities and crop residue. It might be a source of energy when it is burnt. Geothermal energy is energy produced from hot, dry rocks, magma, hot water springs and natural geysers. Ocean thermal is energy produced from waves and tidal waves.
With regards to renewable energy, the most powerful and useful may be the sun. The sun is available from sunrise to sunset and produces an unimaginable quantity of energy each and everyday. What solar collectors do would be to harness the energy from your sun in the form of radiation being usable forms of energy for example heat and electricity, Cells in particular converts sunshine into electricity. With technology being so advanced, cells are taken to a brand new level. There are motorhomes, cell phones and cars.
Solar Heat
Solar heating systems rely on a source of bright light, a surface or liquid that can absorb light plus a storage device for the resulting heat generated. A greenhouse is a useful one of this effect. Solar heat is certainly the cheapest and most practical kind of renewable energy in the world. Some practical uses are water heaters, ovens, cookers and warming.
Green Living - Wind Energy
From times long, way back when, sailing ships been dependent on the energy of the wind to get across oceans. Likewise wind energy have also been used to work windmills for pumping water. Today, wind power will be used as a clean source of electricity around the world. Wind farms, because they are often called can provide enough electricity for a large number of homes at a time. The power of wind is used to make turbines, which in turn is linked to an electrical generator and the gearbox inside the generator converts the energy of the spinning turbine into electricity.
Water Power
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% with the electricity in Canada and 60% in the usa.
