Renewable Energy is energy based on resources that are regenerative and all practical purposes can't be depleted. 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 way to obtain clean and limitless energy. Fundamental essentials non-conventional sources of energy. A lot of the renewable sources of energy are fairly non-polluting and considered clean with the exception of biomass, a renewable source, is 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 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, hot water springs and natural geysers. Ocean thermal is energy produced from waves and tidal waves.
When it comes to renewable energy, the most powerful and useful may be the sun. The sun can be obtained from sunrise to sunset and produces an unimaginable level of energy each and everyday. What solar collectors do is to harness the energy in the sun in the form of radiation to become usable forms of energy including heat and electricity, Cells in particular converts the sun's energy into electricity. With technology being so advanced, cells are taken to a new level. There are motorhomes, cell phones and cars.
Solar heating systems depend on a source of bright light, a surface or liquid that can absorb light along with a storage device for the resulting heat generated. A greenhouse is a good example of this effect. Solar heat is by far the cheapest and most practical type of renewable energy in the world. Some practical uses are hot water heaters, ovens, cookers and warming.
Green Living - Wind Energy
From times long, sometime ago, sailing ships relied 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 is being used as a clean electric source around the world. Wind farms, because 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 as well as the gearbox inside the generator converts the vitality of the spinning turbine into electricity.
Ages ago, waterwheels were used to offer power for grain mills and lumber cutting. Hydroelectricity, since it is called today, produces over 60% from the electricity in Canada and 60% in the usa.
