The sources of energy which are inexhaustible and are being continuously supplied by nature are known as renewables sources of energy. This note provides us an information about sources of energy and conservation of energy.
The process in which the heavy nucleus of a radioactive atom splits up into smaller nuclei when bombarded low energy neutrons is called nuclear fission. This note provides us an information on nuclear energy and hydroelectric power plant.
Biogas is a mixture of various gases formed when the animal dung is mixed with water and ferment in the absence of air. A device used to convert wind energy into the mechanical energy of the machine is called windmill. This note provides us with an information on the wind and bio-mass energy.
The energy emitted by the sun in the form of heat and light is known as solar energy. This note provides us an information on solar energy and solar devices.
The heat energy stored in the hot spots of the earth’s crust is called geothermal energy. This note provides us an information on solar devices and various source of energy.
Pollution is the addition of something in the ecosystem, which has a detrimental effect on the environment. This note provides us an information on use of energy and pollution.
If there is an excess of carbon dioxide in the atmosphere, the temperature of the earth increases which is called global warming. This note provides us an information on global warming, acid rain and the greenhouse effect.
