Renewable Energy is energy derived from resources that are regenerative and all practical purposes cannot be depleted. Sources such sunlight and the wind, cannot be exhausted and for that reason called renewable. They cause fewer emissions are available locally. Their use can, to a large extent, reduce chemical, radioactive and thermal pollution. They may be a viable supply of clean and limitless energy. These are the basic non-conventional sources of energy. Most of the renewable sources of energy are fairly non-polluting and considered clean aside from biomass, a renewable source, is really a major polluter indoors.
Causes of renewable energy or non-conventional energy would be 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 when it's burnt. Geothermal energy is energy based on hot, dry rocks, magma, domestic hot water springs and natural geysers. Ocean thermal is energy based on waves and tidal waves.
In terms of renewable energy, the most powerful and useful will be the sun. The sun is available from sunrise to sunset and produces an unimaginable level of energy each and everyday. What solar collectors do would be to harness the energy from the sun in the form of radiation being usable forms of energy including 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 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 definitely 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 relied on the energy of the wind depict oceans. Likewise wind energy seemed to be used to work windmills for pumping water. Today, wind power has been 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 strength of wind is used to turn turbines, which in turn is attached to an electrical generator and the gearbox inside the generator converts the vitality 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, as it is called today, produces over 60% with the electricity in Canada and 60% in america.
