Renewable Energy is energy based on resources that are regenerative or all practical purposes can't be depleted. Sources such the sun's rays and the wind, can't ever be exhausted and therefore called renewable. They cause fewer emissions are available locally. Their use can, to some large extent, reduce chemical, radioactive and thermal pollution. They may be a viable supply of clean and limitless energy. These are the non-conventional sources of energy. A lot of the renewable sources of energy are fairly non-polluting and considered clean except for biomass, a renewable source, is really a major polluter indoors.
Reasons for renewable energy or non-conventional energy would be the sun, wind, agricultural residue, firewood and animal dung. Energy generated in the sun is known as solar energy. Energy derived from water is named hydroelectricity. Biomass is firewood, animal dung, biodegradable waste from cities and crop residue. It becomes a source of energy when 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.
When it comes to renewable energy, the most powerful and useful may be the sun. The sun is accessible from sunrise to sunset and produces an unimaginable quantity of energy each and everyday. What solar collectors do is to harness the energy from the sun in the form of radiation to be usable forms of energy such as heat and electricity, Cells in particular converts sunshine into electricity. With technology being so advanced, solar panels are taken to a fresh 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 will absorb light plus a storage device for the resulting heat generated. A greenhouse is a good example of this effect. Solar heat is definitely the cheapest and most practical form of renewable energy in the world. Some practical uses are water heaters, ovens, cookers and warming.
Green Living - Wind Energy
From times long, sometime ago, sailing ships depended on the energy of the wind depict oceans. Likewise wind energy was also used to work windmills for pumping water. Today, wind power has been used as a clean source of electricity 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 turn turbines, which in turn is linked to an electrical generator as well as the gearbox inside the generator converts the energy of the spinning turbine into electricity.
Water Power
Centuries ago, waterwheels were used to offer power for grain mills and lumber cutting. Hydroelectricity, as it is called today, produces over 60% of the electricity in Canada and 60% in the usa.
