India can meet its energy needs without nuclear plants: Study

October 4, 2012

 

nuclear_plantsBangalore, October 4: India's energy needs can be met entirely by solar and other renewable sources, says a new study by two professors at the Indian Institute of Science (IISc) in Bangalore.  Their report published in the journal Current Science may add ammunition to the anti-nuclear agitation in India.

 

The analysis by Hiremath Mitavachan and Jayaraman  Srinivasan of  IISc's Divecha Centre for Climate Change overturns the argument that nuclear power is essential for India because the country does not have enough land to exploit the potential of solar energy in India.

 

According to their study, 4.1 percent of the total uncultivable and waste land area in India  is enough to meet the projected annual demand of 3,400 terawatt-hour (TWh) by 2070 by solar energy alone (1 terawatt-hour per year equals 114 megawatts). The land area required will be further reduced to 3.1 percent "if we bring the other potential renewable energy sources of India into picture", they claim. They conclude that land availability is not a limiting constraint for the solar source as believed.

 

They say their calculations are based on present-day solar photovoltaic (PV) technology and do not include higher efficiencies achieved by new solar cells. Neither have they considered roof-top PV systems that can be established without any need for additional land.

 

The IISc researchers' conclusion is in conformity with that of a report prepared last year  by the Australian government which said: "There is more than enough suitable land in India, with high direct beam solar, to meet the entire nation's electricity needs in principle."

 

Convinced that sunlight differs from other energy sources in the way it uses the land, the researchers compared the land-use pattern of three primary energy sources - coal, nuclear and hydro - with solar energy.  They then calculated the percentage of India's land area that would be required to meet the future projected energy demand. Coal power plants not only transform the land around the facility but also require land for mining coal and its upstream processing, the authors note.  An average dam displaces 31,340 persons and submerges 8,748 hectares of land. The direct land footprint of a nuclear power plant includes power plant area, buffer zone, waste disposal area and the land that goes into mining uranium.

 

"Our study shows that solar power plants require less land in comparison to hydro-power plants and are comparable with coal and nuclear energy power generation when life-cycle transformations are considered," Srinivasan said.

 

While nuclear and fossil fuel-based technologies must continuously transform some land to extract the fuels or dispose of the waste, this is not the case with solar plants. In fact, the same land used for PV solar power plants can be utilised for other purposes like grazing.

 

The roof-top solar power technology, along with that proposed by IISc professors, "will be able to meet most of the electricity demand, and has the potential to transform the power sector," says Shankar Sarma, a power policy analyst  and author of forthcoming book "Integrated Power Policy."

 

Atul  Chokshi of the IISc Department of Materials Engineering and an expert on solar energy agrees. He reported recently  that a three kilowatt  rooftop solar panel system on the 425 million households   can generate a total energy per year 1900 TWh - half of the projected energy demand by 2070.

New Delhi, May 17: Following the COVID-19-induced economic disruptions, up to 135 million jobs could be lost and 120 million people might be pushed back into poverty in India, all of which will have a hit on consumer income, spending and savings, says a report.

According to a new report by international management consulting firm Arthur D Little, the worst of COVID-19's impact will be felt by India's most vulnerable in terms of job loss, poverty increase and reduced per-capita income, which in turn will result in a steep decline in the Gross Domestic Product (GDP).

"Given the continued rise of COVID-19 cases, we believe that a W-shaped recovery is the most likely scenario for India. This implies a GDP contraction of 10.8 per cent in FY 2020-21 and GDP growth of 0.8 per cent in FY 2021-22," the report said.

India's COVID-19 tally has crossed 90,000 and the nationwide death toll has touched nearly 2,800 so far.

The report titled "India: Surmounting the economic challenges posed by COVID-19: A 10-point programme to revive and power India's post-COVID economy" said the 'collateral damage' of the forecasted GDP slowdown, will be felt most acutely in employment, poverty alleviation, per-capita income and overall nominal GDP.

"Unemployment may rise to 35 per cent from 7.6 per cent resulting in 136 million jobs lost and a total of 174 million unemployed. Poverty alleviation will receive a set-back, significantly changing the fortunes of many, putting 120 million people into poverty and 40 million into abject poverty," the report said.

"India is headed towards a W-shaped economic recovery with a potential GDP contraction of 10.8 per cent in FY21. An opportunity loss of USD 1 trillion is staring India in its face," said Barnik Chitran Maitra, lead author of the report and Managing Partner & CEO of Arthur D Little, India and South Asia.

Maitra further said "for its USD 5 trillion vision, a radical economic approach is needed, centred on an immediate stimulus and structural reforms. The Prime Minister's visionary 'Atma Nirbhar Bharat Abhiyan' is a good start to this new approach."

The report lauded the steps taken by the government and the Reserve Bank of India, but said a far more assertive approach may be required given the magnitude of the adverse economic output.

The report suggested a 10-point programme to accelerate the recovery which include strengthening the 'safety net' significantly for the most vulnerable, enable survival of small and medium businesses, restarting the rural economy and providing targeted assistance to at-risk sectors.

It further said the government should launch "Make in India 2.0" to capture global opportunities, build 'Modern India', accelerate Digital India and Innovation, strengthen global investment corridors with the US, UAE, Saudi Arabia, Japan and the UK, debottleneck land and labour and transform banking and financial markets in a bid to secure a sustainable economic future for 1.3 billion Indians.

New Delhi, Feb 19: India will switch to the world's cleanest petrol and diesel from April 1 as it leapfrogs straight to Euro-VI emission compliant fuels from Euro-IV grades now - a feat achieved in just three years and not seen in any of the large economies around the globe.

India will join the select league of nations using petrol and diesel containing just 10 parts per million of sulphur as it looks to cut vehicular emissions that are said to be one of the reasons for the choking pollution in major cities.

Sanjiv Singh, Chairman of Indian Oil Corp (IOC) - the firm that controls roughly half of the country's fuel market, said almost all refineries began producing ultra-low sulphur BS-VI (equivalent to Euro-VI grade) petrol and diesel by the end of 2019 and oil companies have now undertaken the tedious task of replacing every drop of fuel in the country with the new one.

"We are absolutely on track for supplying BS-VI fuel from April 1. Almost all refineries have begun supplying BS-VI fuel and the same has reached storage depots across the country," he said.

From storage depots, the fuel has started travelling to petrol pumps and in the next few weeks all of them will only have BS-VI grade petrol and diesel, he said. "We are 100 per cent confident that fuel that will flow from nozzles at all the petrol pumps in the country on April 1 will be BS-VI emission compliant fuel."

India adopted Euro-III equivalent (or Bharat Stage-III) fuel with a sulphur content of 350 ppm in 2010 and then took seven years to move to BS-IV that had a sulphur content of 50 ppm. From BS-IV to BS-VI it took just three years.

"It was a conscious decision to leapfrog to BS-VI as first upgrading to BS-V and then shifting to BS-VI would have prolonged the journey to 4 to 6 years. Besides, oil refineries, as well as automobile manufacturers, would have had to make investments twice - first to producing BS-V grade fuel and engines and then BS-VI ones," he said.

State-owned oil refineries spent about Rs 35,000 crore to upgrade plants that could produce ultra-low sulphur fuel. This investment is on top of Rs 60,000 crore they spent on refinery upgrades in the previous switchovers.

BS-VI has a sulphur content of just 10 ppm and emission standards are as good as CNG.

Originally, Delhi and its adjoining towns were to have BS-VI fuel supplies by April 2019 and the rest of the country was to get same supplies from April 2020.

But oil marketing companies switched over to supply of BS-VI grade fuels in the national capital territory of Delhi on April 1, 2018.

The supply of BS-VI fuels was further extended to four contiguous districts of Rajasthan and eight of Uttar Pradesh in the National Capital Region (NCR) on April 1, 2019, together with the city of Agra.

BS-VI grade fuels were made available in 7 districts of Haryana from October 1, 2019.

Singh said the new fuel will result in a reduction in NOx in BS-VI compliant vehicles by 25 per cent in petrol cars and by 70 per cent in diesel cars.

The switchover, he said, is a tedious task as every drop of old, higher-sulphur content fuel has to be flushed out in depots, pipelines and tanks before being replaced by BS-VI.

"We are confident of disruption-free switchover to BS-VI supplies across the country," he said. "What we will be supplying is the best quality available anywhere in the world. You don't have any better fuel that is supplied in any part of the world. Perhaps our BS-VI fuel will be better than equivalent fuel in some parts of the US and Europe."

India adopted a fuel upgradation programme in the early 1990s. Low lead gasoline (petrol) was introduced in 1994 in Delhi, Mumbai, Kolkata and Chennai. On February 1, 2000, unleaded gasoline was mandated nationwide.

Similarly, BS-2000 (Euro-I equivalent, BS-1) vehicle emission norms were introduced for new vehicles from April 2000. BS-II (Euro-II equivalent) emission norms for new cars were introduced in Delhi from 2000 and extended to the other metro cities in 2001.

Benzene limits have been reduced progressively from 5 per cent in 2000 to 1 per cent nationwide. Lead content in gasoline was removed in phases and only unleaded gasoline is being produced and sold from February 1, 2000.

The octane number of gasoline signifies the improved performance of the engine. Loss in octane number due to phasing out of lead was made up by installing new facilities in the refinery and changes in refinery operation. RON (Research Octane Number) of gasoline for BS-2000 spec was increased to 88. This has over time been increased to 91.

Singh said sulphur reduction will reduce Particulate Matter (PM) emissions even in the in-use older generation diesel vehicles.

Lucknow, Feb 16: Resident doctors at the AMU's Jawaharlal Nehru Hospital on Sunday demanded that the charges slapped against Dr Kafeel Khan under the National Security Act be withdrawn.

Dr Khan was arrested by the UP Special Task Force from Mumbai on January 29 in connection with a speech he had delivered during an anti-CAA protest at Aligarh Muslim University on December 12.

The Resident Doctors' Association (RDA) held a protest march on the hospital campus against the slapping of the NSA against the Gorakhpur doctor after he was granted bail in connection with the alleged hate speech.

RDA president Dr Hamza Malik said the move was a "blatant attempt to crush dissent and a violation of the Constitution of india".

He said by targeting the doctor, the UP government had done a great disservice to the entire medical community.

The AMU Students' Coordination Committee also described the decision to charge Dr Kafeel under the NSA a "direct assault" on a member of the medical fraternity who is "known for his upright behaviour and a champion of free speech".

Committee spokesperson and former AMU Students' Union president Faizul Hasan said by charging Dr Kafeel under the NSA even after he got bail was "a direct violation of a Supreme Court ruling on such issues".

Hasan said Dr Kafeel's fate should serve as an eye-opener for the rest of the country regarding the democratic rights in Uttar Pradesh.

The doctor was earlier arrested for his alleged role in the death of over 60 children within an week at the BRD Medical College in Gorakhpur in August 2017. Short supply of oxygen at the children's ward was blamed at that time for the deaths.

About two years later, a state government probe cleared Khan of all major charges, prompting him to seek an apology from the Yogi Adityanath government.
