Essay On Wind Energy In India

This article needs to be updated. Please update this article to reflect recent events or newly available information.(December 2017)

India is running one of the largest and most ambitious renewable capacity expansion programs in the world. Newer renewable electricity sources are projected to grow massively by nearer term 2022 targets, including a more than doubling of India's large wind power capacity and an almost 15 fold increase in solar power from April 2016 levels. Such ambitious targets would place India amongst the world leaders in renewable energy use and place India at the centre of its "Sunshine Countries" International Solar Alliance project promoting the growth and development of solar power internationally to over 120 countries. Renewable energy in India comes under the purview of the Ministry of New and Renewable Energy (MNRE). India was the first country in the world to set up a ministry of non-conventional energy resources, in the early 1980s. Solar Energy Corporation of India is responsible for the development of solar energy industry in India. Hydroelectricity is administered separately by the Ministry of Power and not included in MNRE targets.

In the electricity sector renewable energy (excluding large hydro) accounted for 18.37% of the total installed power capacity (60.98 GW) in India as of 31 October 2017.[1] In previous years the share of renewable grid capacity increased 6 fold from 2% (3.9 GW) in 2002 to around 13% (36 GW) by 2015.[2] India set a target of achieving 40% of its total electricity grid capacity generation from non-fossil fuel sources by 2030, as stated in its Intended Nationally Determined Contributions statement in the Paris Agreement.[3][2]

Large hydro installed capacity reached 44.41 GW[4] as of 28 February 2017 contributing to 13.6% of the total power capacity. Unlike most countries, India does not count large hydro power while accounting for renewable energy targets.Thus, renewable energy including large scale hydro-power currently adds up to more than 32% of the total installed power capacity in India.

Wind power capacity attained 32,746 MW, making India the fourth-largest wind power producer in the world as of year end 2017. According to a government press release dated 27 December 2017 the country had a strong manufacturing base in wind power with 20 manufactures of 53 different wind turbine models of international quality up to 3 MW in size with exports to Europe the USA and other countries.[1]

Installed solar power reached over 20 GW as of January 2018, through both solar parks as well as roof-top solar panels.[1] Three of the top six largest solar parks worldwide are in India including the third largest solar park in the world at Kurnool, Andhra Pradesh, with a capcity of 1000 MW.

Biomass power from biomass combustion, biomass gasification and bagasseco-generation reached 8.18 GW installed capacity as of 30 November 2017.[1] Family type biogas plants reached 3.98 million biogas plants by the same date.[1]

Renewable energy overview and targets[edit]

The 2022 electrical power targets include achieving 175 GW of energy from renewable sources - nearly 100 GW through solar power, 60 GW from wind power, 10 GW from biomass power and 5GW from small hydro power.[7] The bidding process for the further additional 115 GW or thereabouts to meet these targets of installed capacity from January 2018 levels will be completed by the end of 2019-2020.[8] The government has announced that no new coal-based capacity addition is required beyond the 50 GW under different stages of construction likely to come online between 2017 and 2022.

TOTAL60,985.21175,000.00

* The target is given for "bio-power" which includes biomass power and waste to power generation.

The figures above refer to newer and fast developing renewable energy sources and are managed by the Ministry for New and Renewable Energy (MNRE). In addition as of 31 December 2016 India had 50,017.97 MW of installed large hydro capacity, which comes under the ambit of Ministry of Power.[4]

In terms of meeting its ambitious 2022 targets, as of 31 March 2017, wind power was more than halfway towards its goal, whilst solar power was below 13% of its highly ambitious target, although expansion is expected to be dramatic in the near future. Bio energy was at just above 80% mark whilst small hydro power was already 85% of the way to meet its target. Overall India was at 33% towards meeting its 2022 renewable installed power capacity target of 175 GW. The total breakdown of installed grid connected capacity from all sources including large hydro was as follows:

SourceInstalled Capacity (MW)Share
Coal189,047.8859.93%
RES MNRE50,018.0015.86%
Large Hydro44,413.4314.08%
Gas25,329.388.03%
Diesel837.630.27%
Nuclear5,780.001.83%
Total315,426.32100.00%

The first figure at the top of the table refers to the fast growing renewable energy sources under the responsibility of the Ministry for New and Renewable Energy and slightly exceeded the installed capacity of large hydro installations. This figure is targeted to reach 175 GW by 2022. Coal power currently represents the largest share of installed capacity at just under 186 GW. Total installed capacity as of 30 April 2016, for grid connected power in India stood at a little under 303 GW.[11]

Large hydropower[edit]

India is the 7th largest producer of hydroelectric power in the world. As of 30 April 2017, India's installed utility-scale hydroelectric capacity was 44,594 MW, or 13.5% of its total utility power generation capacity.[12]

Small hydropower[edit]

Additional smaller hydroelectric power units with a total capacity of 4,380 MW (1.3% of its total utility power generation capacity) have been installed.[13][14] Small hydropower comes under the ambit of the Ministry of New and Renewable energy (MNRE) whilst large hydro comes under the ambit of Ministry of Power.[4]

Wind power[edit]

Main article: Wind power in India

The development of wind power in India began in the 1990s, and has significantly increased in the last few years. Although a relative newcomer to the wind industry compared with Denmark or the US, domestic policy support for wind power has led India to become the country with the fourth largest installed wind power capacity in the world.[15]

As of 28 February 2017 the installed capacity of wind power in India was 29151.29 MW,[5] mainly spread across Tamil Nadu (7,269.50 MW), Maharashtra (4,100.40 MW), Gujarat (3,454.30 MW), Rajasthan (2,784.90 MW), Karnataka (2,318.20 MW), Andhra Pradesh (746.20 MW) and Madhya Pradesh (423.40 MW)[16] Wind power accounts for 14% of India's total installed power capacity.[17] India has set an ambitious target to generate 60,000 MW of electricity from wind power by 2022.[18]

Some of India's largest wind farms are:

Solar power[edit]

Main article: Solar power in India

India is densely populated and has high solar insolation, an ideal combination for using solar power in India. Much of the country does not have an electrical grid, so one of the first applications of solar power has been for water pumping, to begin replacing India's four to five million diesel powered water pumps, each consuming about 3.5 kilowatts, and off-grid lighting. Some large projects have been proposed, and a 35,000 km2 (14,000 sq mi) area of the Thar Desert has been set aside for solar power projects, sufficient to generate 700 to 2,100 gigawatts. Solar power in India has been growing at a rate of 113% yoy[27] and now dropped to around ₹4.34 (6.6¢ US) per kWh, which is around 18% lower than the average price for electricity generated by coal-fired plants.[28][29]

As part of India's ambitious solar programme the central government has set up a US$350 million fund and the Yes Bank will loan US$5 billion to finance solar projects (c. January 2018).[8] India is also the home to the world's first and only 100% solar powered airport, located at Cochin, Kerala[30]

The Indian Solar Loan Programme, supported by the United Nations Environment Programme has won the prestigious Energy Globe World award for Sustainability for helping to establish a consumer financing program for solar home power systems. Over the span of three years more than 16,000 solar home systems have been financed through 2,000 bank branches, particularly in rural areas of South India where the electricity grid does not yet extend.[31][32]

Announced in November 2009, the Government of India proposed to launch its Jawaharlal Nehru National Solar Mission under the National Action Plan on Climate Change with plans to generate 1,000 MW of power by 2013 and up to 20,000 MW grid-based solar power, 2,000 MW of off-grid solar power and cover 20×106 m2 (220×106 sq ft) with collectors by the end of the final phase of the mission in 2020.[33] The Mission aims to achieve grid parity (electricity delivered at the same cost and quality as that delivered on the grid) by 2020. Achieving this target would establish India as a global leader in solar power generation.[34]

Launched in 2003, the Indian Solar Loan Programme was a four-year partnership between UNEP, the UNEP Risoe Centre, and two of India's largest banks, the Canara Bank and Syndicate Bank.[32]

Waste to energy[edit]

Every year, about 55 million tonnes of municipal solid waste (MSW) and 38 billion litres of sewage are generated in the urban areas of India. In addition, large quantities of solid and liquid wastes are generated by industries. Waste generation in India is expected to increase rapidly in the future. As more people migrate to urban areas and as incomes increase, consumption levels are likely to rise, as are rates of waste generation. It is estimated that the amount of waste generated in India will increase at a per capita rate of approximately 1-1.33% annually. This has significant impacts on the amount of land that is and will be needed for disposal, economic costs of collecting and transporting waste, and the environmental consequences of increased MSW generation levels.[35]

India has had a long involvement with anaerobic digestion and biogas technologies. Waste water treatment plants in the country have been established which produce renewable energy from sewage gas. However, there is still significant untapped potential.[36] Also wastes from the distillery sector are on some sites converted into biogas to run in a gas engine to generate onsite power. Prominent companies in the waste to energy sector include:[37]

  • A2Z Group of companies
  • Hanjer Biotech Energies
  • Ramky Enviro Engineers Ltd
  • Hitachi Zosen India Pvt Limited
  • Clarke Energy
  • ORS Group

Biomass[edit]

India is an ideal environment for Biomass production given its tropical location and abundant sunshine and rains. The countries vast agricultural potential provides huge agro-residues which can be used to meet energy needs, both in heat and power applications..According to IREDA "Biomass is capable of supplementing the coal to the tune of about 260 million tonnes", "saving of about Rs. 250 billion, every year."[38] It is estimated that the potential for biomass energy in India includes 16,000 MW from biomass energy and a further 3,500 MW from bagasse cogeneration.[38] Biomass materials that can be used for power generation include bagasse, rice husk, straw, cotton stalk, coconut shells, soya husk, de-oiled cakes, coffee waste, jute wastes, and groundnut shells and saw dust.

Type of Agro residuesQuantity(Million Tonnes / annum)
Straws of various pulses & cereals225.50
Bagasse31.00
Rice Husk10.00
Groundnut shell11.10
Stalks2.00
Various Oil Stalks4.50
Others65.90
Total350.00

Biofuel[edit]

Ethanol[edit]

Ethanol market penetration reached its highest figure of a 3.3% blend rate in India in 2016.[39] It is produced from sugarcane molasses and partly from grains and can be blended with gasoline. Sugarcane or sugarcane juice may cannot be used for the production of ethanol in India.

Biodiesel[edit]

The market for biodiesel remains at an early stage in India with the country achieving a minimal blend rate with diesel of 0.001% in 2016.[39] Intitally development was focussed on the jatropha ( jatropha curcas) plant as the most suitable indedible oilseed for biodiesel production. Development of biodiesel from jatropha has met a number of agronomical and economic restraints and attention is now moving towards other feedstock technologies which utilize used cooking oils, other unusuable oil fractions, animal fat and indedible oils.[39]

Wind - A Renewable Energy Source

Wind is called a renewable energy source because wind will continually be produced as long as the sun shines on the earth. The sun’s contribution to wind energy deals with converting air into heat or cool wind. Wind is produced by the irregular heating of the earth’s surface by the sun. On land, the warm air spreads and goes up in the sky, in the water, heavier and cooler air moves in to take the warm air’s place, thus providing local winds. This power source should be used more often in the United States for its safer standards regarding the environment and finance.

To capture this wind, turbines are used to convert the renewable resource into electricity. The energy in motion or…show more content…

Therefore, similar to the rest of the types of power, wind is not nearly perfected to utilization.

Besides the sight of windmills looks as if it is sticking out like a sore thumb, wind turbines cause animal deaths and noise pollution to plants. “Some news has been reported there are birds fatalities do to flying through the windmills” (www.awea.org). Imagine the sight when a pigeon flies through a rotating shaft made out of blades. Pretty disgusting; birds had it on them for using the bathroom and flushing their feces on top of our cars.

Wind energy is an environment friendly resource the United States should use more than fossil fuels. Do to the fact that coal and wind has the same electricity efficiency; wind should prevail because it doesn’t produce polluting gases such as carbon dioxide. Regardless of the bird fatalities, wind energy is much more animal beneficial than fossil fuels given that such power sources as coal, it is much more injurious do to the fact that it has been inhaled by many beings which causes harmful and most of the time deaths. Let’s use a cleaner source that we can depend on; wind energy.
