Renewable Energy is energy based on resources that are regenerative and all practical purposes can't be depleted. Sources such the sun's rays and the wind, can't ever be exhausted and for that reason called renewable. They cause fewer emissions and are avalable locally. Their use can, with a large extent, reduce chemical, radioactive and thermal pollution. They may be a viable supply of clean and limitless energy. Fundamental essentials non-conventional sources of energy. The majority of the renewable sources of energy are fairly non-polluting and considered clean except for biomass, a renewable source, can be a major polluter indoors.

Sources of renewable energy or non-conventional energy are the sun, wind, agricultural residue, firewood and animal dung. Energy generated from the sun is known as solar technology. Energy derived from water is known as hydroelectricity. Biomass is firewood, animal dung, biodegradable waste from cities and crop residue. It might be a source of energy when it's burnt. Geothermal energy is energy derived from hot, dry rocks, magma, domestic hot water springs and natural geysers. Ocean thermal is energy produced from waves and tidal waves.

Solar Power

With regards 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 would be to harness the energy from your sun in the form of radiation to become usable forms of energy such as heat and electricity, Solar panels in particular converts sunshine into electricity. With technology being so advanced, cells 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 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 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, long ago, sailing ships relied on the energy of the wind to get across oceans. Likewise wind energy was also used to work windmills for pumping water. Today, wind power will be used as a clean electrical source around the world. Wind farms, as they are often called can provide enough electricity for a large number of homes at a time. The strength of wind is used to turn turbines, which in turn is connected to an electrical generator as well as the gearbox inside the generator converts the vitality 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 the usa.
