Renewable Energy is energy derived from resources that are regenerative or all practical purposes cannot be depleted. Sources such the sun and the wind, cannot be exhausted and for that reason called renewable. They cause fewer emissions and are avalable locally. Their use can, to a large extent, reduce chemical, radioactive and thermal pollution. They are a viable source 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 aside from biomass, a renewable source, can be a major polluter indoors.
Reasons for renewable energy or non-conventional energy will be the sun, wind, agricultural residue, firewood and animal dung. Energy generated in the sun is known as solar power. Energy derived from water is called 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 based on hot, dry rocks, magma, hot water springs and natural geysers. Ocean thermal is energy derived from waves and tidal waves.
With regards to renewable energy, the most powerful and useful is 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 from your sun in the form of radiation to be usable forms of energy for example heat and electricity, Cells in particular converts sunshine into electricity. With technology being so advanced, solar panels are taken to a brand new level. There are motorhomes, cell phones and cars.
Solar Heat
Solar heating systems depend 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 useful one of this effect. Solar heat is by far the cheapest and most practical type of renewable energy in the world. Some practical uses are water heaters, ovens, cookers and home heating.
Green Living - Wind Energy
From times long, long ago, sailing ships been dependent on the energy of the wind depict oceans. Likewise wind energy seemed to be used to work windmills for pumping water. Today, wind power will be used as a clean electrical source around the world. Wind farms, since they are often called can provide enough electricity for 1000s of homes at a time. The strength 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
Ages ago, waterwheels were used to offer power for grain mills and lumber cutting. Hydroelectricity, since it is called today, produces over 60% of the electricity in Canada and 60% in america.
