Renewable Energy Types

Introduction to renewable energy types:

We are dependent upon different sources of energy in one way or the other, directly for our energy requirements. Energy is a vital requirement for economic development. Increasing amounts of energy are needed to improve agricultural production, to turn the wheels of industry, to provide goods and services throughout the nation an to improve the quality of life of our people.

The energy sources that can be replenished , when once they are used up, are called renewable energy sources.

Ex : Solar energy , wind energy  , water - power and bio - mass energy.

I like to share this Definition for Kinetic Energy with you all through my article.

Solar energy : renewable energy types


Solar energy : The SUN is the most direct and bountiful source of energy. It powers the flow of wind and water cycles on the earth's surface and sustains all life on the planet. Plants, which are Nature's Green factories, use this energy to make their food. This food provides sustenance to man and other animals on earth. Without sunlight, the earth would be a cold and dead planet. Energy radiated by the sun is free, non - polluting and limitless. The problem is to collect, use and store this energy efficiently and economically. Let us see Different types of Renewable Energy sources


Different types of Renewable Energy sources


Water Power :  Running water is a source of renewable energy . This is freely available and does not pollute the environment. Water stored in dams is used to generate electricity. These Hydal Power stations are able to meet only 6% of world's energy requirements.

Tidal Energy : Tidal energy is a renewable source of energy. The daily rise and fall of the tides can be used to drive turbines for generating turbines for generating electricity. Tidal energy will prove to be a good and valuable source of energy in all the coastal areas of the world in the near future.

Bio-gas : Bio-gas, is a renewable source of energy . It is produced mainly from cow dung , sewage, crop residues, vegetable wastes, water hyacinth, poultry droppings, pig manure, etc. The material contained in the bodies of plants and animals is called Biomass . When organisms die their bio-mass can be used as fuel for domestic purposes. Animal and plant wastes are easily degraded by anaerobic micro- organisms in the presence of water, producing gases such as methane , carbon dioxide , hydrogen , hydrogen sulphide. This mixture of gases is called Bio-gas. It contains about 65% of methane which is an excellent fuel. It can be utilised for cooking, lighting and generation of electricity for use in agriculture and rural industry.

Having problem with The Problems of Work keep reading my upcoming posts, i will try to help you.

Geothermal Energy : The interior of earth is hot. Water seeping down deep into the earth is turned into steam and this can be supplied to homes for heating purposes and for generating electricity. Electricity produced in this way costs less than electricity from other sources.

Wind Energy : Wind is the motion of air. It is caused by differences in temperature and pressure in adjacent locations. The larger the pressure differences, the stronger will be the winds. Wind mills extract the kinetic energy, and convert it into useful electric power. Wind energy is in use since a long time and newer wind machines are being developed. Wind generators could be used in places that have fairly strong and fairly constant flow of winds. Sail-type wind mills and metal-vane windmills are being installed at several locations in our country. This is a pollution free, renewable source of energy.
