Alternative Energy

Today, alternative sources of energy are getting popularity all over the world. Alternative energy is cost-effective, renewable, eco friendly and easy to use. The most famous and developed types of alternative energy are solar energy, nuclear energy and hydro electricity. About 90% of the global energy comprises hydroelectricity. Also, this alternative source of energy accounts for 20% of the world's electricity. Hydroelectricity is one of the most popular, widely used and ancient form of alternative energy. Every form of alternative energy works on its own set of sources of energy. We can tap the ubiquitous form of alternative energy using solar panels, photovoltaic cells and solar calculators. Solar energy is used to keep homes warm and generating electricity.

Solar technology can be categorized into two major parts i.e., active solar and passive solar techniques. In passive solar technique sunlight converted into usable heat without using any active mechanical system. Few passive systems use conventional energy to control shutters, night insulation, dampers and other devices to enhance the collection the collection of solar energy.

Wind energy is one of the alternative sources of energy. Windmills are built to produce wind energy. The technology of wind energy is simple; therefore, can be replicated at any place with gusty winds. Nuclear energy is not so old mode of alternative energy. There are two ways of producing nuclear energy. Nuclear fusion reaction includes splitting on an atom.

Besides these alternative sources of energy, there are many sources also available.
