Alternative power sources

Alternative power can be obtained from alternative sources of energy. It can be put to several uses and is at present one of the most important renewable sources of energy available.

Solar power is the power generated from the energy of the sun. Solar power can be in the form of heat or light. It is the most common form of alternative power that can be put to use in everyday life. It is renewable, eco friendly and readily available.

Wind power is the power generated from wind energy by using wind machines or wind turbines. The main use of wind power is for electricity generation. Wind power is a renewable source of energy that does not emit any harmful substances in the atmosphere. However, the use of wind turbines for the generation of wind power may cause noise pollution.

Power from biomass comes from decomposition of plants and animal wastes which is a source of renewable energy. This energy is called biomass. Biomass power plants can be used to convert this biomass into useful alternative power that can be put to several uses.

Geothermal power is the power generated from geothermal energy. Geothermal energy is obtained from inside the earth. This energy in the form of hot water or steam is used to drive turbines that generate geothermal power. This source of alternative power is renewable, clean and non- polluting.

Most countries are using alternative power because it is affordable, renewable and workable.
