Meaning and
Importance of non-conventional sources of energy:
Non
Conventional Energy sources are those energy sources which are renewable and
ecologically safe, such as tidal power, wind power, Solar etc
As the world's
finite supplies of traditional fossil fuels are consumed at a voracious rate by
a continually industrializing world, the development and use of
non-conventional sources of energy is becoming ever more important for the
future of the planet. Some research has shown that fuels such as oil and gas,
and even nuclear, have a remaining lifespan of as little as 70 years
Though non-conventional energy sources, such as solar and wind power, make up a small part of the overall market, they offer benefits not found in traditional sources

*. These are renewable resources. The non-conventional sources of energy can be renewed with minimum effort and money.
*. Non-conventional sources of energy are pollution-free and eco-friendly.....
Shruti, i totally agree with you, In India, non-conventional energy sources consist of those energy sources that are infinite, natural, and restorable. For example, tidal energy, solar energy, and wind energy are nonconventional sources of energy. Fascinatingly, the application of tidal energy and wind energy was operational in the form of energy sources long back when mineral oil, coal, and natural gas were not broadly introduced as conventional sources of energy.
ReplyDeleteIn the beginning, windmills were utilized for taking out water and pounding grains. Running water and wind were applied for direction finding. Currently, some of the important and widely used non conventional sources of energy are tides, wind, solar geothermal heat, and biomass comprising animal waste, agricultural waste, and human body waste. For example, disposals from big metropolitan areas can work as a source of producing biogas. All these non conventional energy sources are unlimited or restorable and are essentially quite economical.
(i) The growing consumption of energy has resulted in the country becoming increasingly dependent on fossil fuels such as coal, oil and gas.
ReplyDelete(ii) Rising prices of oil and gas and their potential shortages have raised uncertainties about the security of energy supply in future, which has serious repercussions on the growth of the national economy.
(iii) Increasing use of fossil fuels also causes serious environmental problems.
Hence, there is a primary need to use renewable energy sources like solar, wind, tidal, biomass and energy from waste material. They are called non-conventional sources of energy.
India is said to be one of the seven largest consumers of energy, but the growing gap between consumption and domestic output is a cause of concern. India’s share in global oil reserves is about 0.5 per cent, whereas its share in global consumption is about 3 per cent. India is still dependent to the extent of 30 to 35 per cent on non-commercial fuel sources like cowdung, firewood, agricultural waste, etc. The growing energy needs of the emerging economics, specifically India, risks enhanced environmental demage from conventional carbon based sources of energy. The pressure on petrol is mounting and we have to concentrate on conservation of petroleum. Towards conservation of petroleum consumption, the government has to ration supplies of cooking gas, kerosene and petrol; improve power generation; focus on alternative source of energy such as solar, wind and bio-fuels; setup energy standards for all vehicles and a mass awareness for conservation. As the country’s petroleum bill grows, and future supplies look volatile or insecure, alternatives need to be explored. Ethanol is an environment-friendly oxidant additive to gasoline. There is a growing interest in biodiesel or ethanol blend. Energy majors are determined to tap biofuels. Special attention is being paid to jatropha cultivation. The corporate sector too is focusing on the biofuels sector. It is estimated that globally about one million hectares would cater to biofuels over the next four years, with an estimated 300,000 hectares contributing each year to biofuels in South East Asia, India and Southern African countries. India will itself produce 2 million tones of biodiesel by 2012.
ReplyDeletePower and Energy sector is in a positive mood and is leaving no missed opportunity to make hay of it, while the sun shines. India has set up a target of 20000 MW of installed capacity by 2022 for harnessing solar energy. It is leaving no stone unturned to become a solar hub in the world. With such earnest efforts, India’s mission to tap solar energy is not a pipe dream.
Renewable Energy technologies like solar, biomass, hydro, etc are deployed both in rural and urban areas to curb the growing gap between the demand and supply of power, which is due to increase in the per capita energy consumption and importantly, the much hyped climate change concerns. At 10464 MW, India presently ranks fifth in the world in wind power generations. The future of solar photovoltaic development in India seems to be very bright. India’s solar mission envisages the promotion of solar energy to harness and distribute environment-friendly power, available with high scalability, for sustainable economic growth by empowering national energy security.
Indian clean development mechanism projects broadly cover a range of sectors viz power generation from renewable energy, particularly wind and hydro power, biomass applications, waste heat and energy recycling. Accelerated growth is expected in renewable energy sector, particularly wind energy sector, solar energy sector, biofuels sector .etc with favourable conditions in terms of potential, technical support facilities, policy framework and regulatory environment, robust manufacturing base, and investors confidence in the country.
L&T invests in non-conventional energy. During 2011-12, L&T sourced 10.48 % of its overall electrical energy consumption from renewable energy sources. Wind energy contributes 10.2% and solar energy generation through rooftop solar panels contributes 0.28%. Of this, L&T IDPL contributed 5.5% from its 8.70 MW wind energy generators located in Tamil Nadu.
ReplyDeleteL&T IDPL recognizes that Green Energy is essential to mitigate global warming and helps maintain a sustainable eco system. Taking this a step further the 8.7 MW of Wind Energy Generators installed by the Company generates Green Power which caters to substantial captive consumption by L&T’s establishments in Tamil Nadu.
L&T IDPL has so far, generated 56.66 million units of wind energy from 2010 and is eligible for 16,128 Carbon Emission Reduction (CER) certificates per year until 2022 due to the carbon reduction from these wind generators.
Promotion Of Non Conventional Energy
ReplyDeleteNatural Resources Management Division has undertaken the following projects. Non-Conventional Energy Promotion works on Solid Waste Management through installing Bio Gas Plants and Incenerators.
