Non Conventional Sources of Energy in India

need of non conventional energy sources

In addition, wastes in metropolitan areas are utilized for generating electrical energy and gas. There are around 300 nuclear reactors all over the world. B Non conventional energy sources : The conventional energy sources discussed above are exhaust­ible and in some cases, installation of plants to get energy is highly expensive. Several renewable energy systems and devices are commercially available. The potential is also significant in paper and textile industries. By making use of solar concentrators, steam at temperatures up to 1000 degree C can be generated. The non-renewable nature of fossil fuels makes complete dependence on these for future energy needs a very dicey affair.

. India, being a tropical country, is well endowed with plenty of solar energy. At the deeper region of earth crust, the solid rock gets melted in to magma, due to very high temperature. Solar Photovoltaic Power — 2. Wind farms are only practical in areas with a lot of wind, and even if the area is known to be windy, there will be moments when no winds blow.

The quantity of waste generated in Class-I cities of the country has been estimated to be about 30 million tones of municipal solid waste and about 4,400 million cubic metres of sewage per annum. Additionally, many tiny and medium-scale solar power plants have been intended for the countryside areas in India. With the gasification plan, these energy plantations spanning approximately 8,000 hectares were generating almost 1. Once we master techniques to harness solar energy, it can be a vital source of power on all planets. Although the Earth intercepts only a very small part of this radiation, this tiny fraction is equivalent to 754 million kilowatts hours per year; photovoltaic technology converts sunlight directly into electricity. Name a device which can be used for cooking so as to save fuel. The programme has been implemented in a very systematic manner.

It is envisaged at known deposits of petroleum in our country will get exhausted by the few decades and coal reserves are expected to last for another hundred years. Biomass gasifier systems of upto 500 kW capacity based on fuel-wood have been developed indigenously and are being manufactured in the country. Employment generation in rural areas. Wind Energy: Wind power is harnessed by setting up a windmill which is used for pumping water, grinding grain and generating electricity. These substances can be burnt to produce heat energy which can be used in the generation of electricity.

Vigorous efforts are being made to promote small hydel projects in North- Eastern region. The cost inputs are only at the initial stage and the power generation starts immediately after commissioning. Write name of four nuclear power reactors located in India. Thus it is capable of solving the twin problems of energy supply in a decentralised manner and helping in sustaining cleaner environment. Biogas technology is taking deep roots in rural India because of certain inherent advantages.

Environmental Consequences Exploiting any source of energy disturbs the environment in some way or the other. Besides producing gas this plant converts gobar into manure. Write two limitations of using wind energy. India has only four nuclear power stations reactors. Total production of natural gas was 31. Fuels : The materials which are burnt to produce heat energy are known as fuels.

Acquiring the real estate to place the windmills, solar panels, algae farm, geothermal facility, nuclear plant, hydropower dam and ocean center requires sizable upfront capital outlays to fund, build, maintain and implement the endeavors properly with infrastructure and technologies that are up to code standards. Harnessing the Wind Wind power is an inexpensive option for collection alternative electric power. It is clear from the table that over two-thirds of the cogeneration potential is accounted for by sugar industry alone. India has about 6% share in the world reserved coal, that may last 250 years more at the present rate of consumption. It is utilized for drawing water, which is an essential requirement in watering agricultural lands in the rural areas. It is used in commercial and domestic purposes.

India has today one of the largest programmes for renewable energy. Disadvantages : a Manufacturing is expensive. Simply speaking more developed a country, higher is the per capita consumption of energy and vice-versa. The coal, petroleum, natural gas and electricity are conventional sources of energy. The success of biogas technology has brought about a sort of Brown Revolution in rural India.
