Renewable Energy is energy based on resources that are regenerative or all practical purposes cannot be depleted. Sources such sunlight and the wind, can't ever be exhausted and for that reason called renewable. They cause fewer emissions and are available locally. Their use can, to a large extent, reduce chemical, radioactive and thermal pollution. They're a viable source 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 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 the sun is known as solar energy. Energy derived from water is called 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, hot water springs and natural geysers. Ocean thermal is energy produced from waves and tidal waves.

Solar Power

In terms of renewable energy, the most powerful and useful may be the sun. The sun is available from sunrise to sunset and produces an unimaginable amount of energy each and everyday. What solar collectors do would be 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 cells are taken to a new 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 along with 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 form 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 depended on the energy of the wind depict oceans. Likewise wind energy was also used to work windmills for pumping water. Today, wind power will be 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 power of wind is used to turn turbines, which in turn is connected to an electrical generator and also the gearbox inside the generator converts the power of the spinning turbine into electricity.

Water Power

Ages ago, waterwheels were used to offer power for grain mills and lumber cutting. Hydroelectricity, because it is called today, produces over 60% of the electricity in Canada and 60% in america.
