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, Mar 27: The Delhi government has arranged to serve lunch and dinner to the needy in 325 schools in Delhi, chief minister Arvind Kejriwal said on Friday amid reports of people going hungry without access to food during the ongoing nationwide lockdown.

From Saturday, arrangements will be put in place to feed about four lakh people daily at different centres across Delhi, he said addressing the media. "We have made arrangements to provide lunch and dinner in 325 schools. Around 500 people will be provided with food in all these schools. So far we were providing food to 20,000 people daily, the number will now increase to around 2,00,000 from today."

He also said that "from tomorrow, we'll be providing food to 4,00,000 people daily. We're distributing the centres across Delhi."

Stating that the total number of confirmed positive COVID-19 cases in Delhi is now 39, Kejriwal said "We are ready to face any challenge.".

"There are a total of 39 coronavirus positive cases in Delhi as of today, of which 29 cases are of those who had come from outside and were kept in quarantine and 10 of these were cases of local transmission," said Kejriwal at a press conference.

The Chief Minister said that a team of 5 doctors has been set up to look into the preparedness needed to deal with an increase in the number of positive cases for coronavirus in future.

He said, "The team of doctors under the chairmanship of Dr Shiv Kumar Sarin, the head of Institute of Liver and Biliary Sciences, presented a detailed report on March 26 on the preparedness needed to deal with a situation if the number of positive cases for coronavirus increases."

"The report has categorized three situations - if the number of positive cases increases to 100 per day, 500 per day and 1000 per day," he said while adding that the doctors have clearly stated what preparedness should be taken for each situation including the number of ventilators, isolation beds, doctors and nurses required.

He also cited concerns raised by chief ministers of several states including Jharkhand's Hemant Soren and West Bengal's Mamata Banerjee.

Kejriwal said "we consider all those living in Delhi as Delhiites and everyone will be taken care of."
The number of cases tested positive for coronavirus rose to 724 on Friday, according to the Ministry of Health and Family Welfare.

The Retailers Association of India (RAI) has said that ad hoc lockdowns by state governments are impacting the businesses of already-stressed retailers, along with hurting the economic revival of the country.

In a statement, the body of the organised retail industry said that the long road to recovery for the Indian retail industry continues to meet stumbling blocks with numerous restrictions being imposed at the state and local levels.

"Total lockdowns in some places and limited operational hours and days in several others are creating setbacks for retailers as the already stressed retail businesses are getting further interrupted and in turn, dampening consumer sentiment," it said.

According to RAI, although the intentions are that of citizen safety and social distancing, the recent instances of local lockdowns and ad hoc restrictions being imposed in Uttar Pradesh, Maharashtra, Andhra Pradesh and Karnataka are having a distressing impact on retail businesses.

Retailers are already facing huge setbacks in terms of payment of wages and rentals due to very low sales of about 40 per cent as compared to last year, thanks to the extended lockdown, it said.

Contesting the restrictions on operating hours, Sandeep Kataria, CEO, Bata India said: "Restricted shopping time can lead to unnecessary overcrowding of stores, which is unfavourable towards the personal safety of both store staff and customers. Longer operational hours will support recovery for retailers as well as help adhering to social distancing norms."

Arvind Mediratta, MD and CEO, METRO Cash & Carry India said that these lockdowns will create severe inconvenience for all citizens as they also bar operations of food and grocery retail and wholesale stores.

Such hastily-implemented decisions by states undermine investor confidence and would come in the way of making the country "aatmanirbhar" or self-reliant, he said.

Voicing the concerns of retailers, the RAI has submitted representations to various state and local authorities that puts forth recommendations to get businesses and life of consumers on the track to recovery.

It has said that authorities should mandatorily allow essential shops including kiranas, general trade shops, supermarkets, hypermarkets and wholesalers to operate every day of the week until 9 p.m. to cater to the daily needs of the customers.

It has also sought ensuring uniform and regular opening of all categories of retail for full working hours while following stringent hygiene practices and adhering to social distancing norms. This will help avoid overcrowding outside stores as demand will get distributed over all days of the week, it said.

The industry body has also asked the local authorities to open malls in all states. Malls can ensure a safe shopping experience wherein safety measures are taken by both, the mall authorities and the retailers, it said.

Kumar Rajagopalan, CEO, RAI, said: "The need of the hour is concerted efforts by all stakeholders. While retailers are doing their bit by following stringent hygiene practices, the policymakers too need to support to ensure economic revival across the country. Consumption is important for the country and supports the business environment."

New Delhi, Feb 23: Hailing the role of first Prime Minister Jawaharlal Nehru in shaping India a modern nation state, former Prime Minister Manmohan Singh on Saturday hit out at the Narendra Modi-led Central government, saying "nationalism" and the slogan of 'Bharat Mata Ki Jai' are being misused to construct a militant and purely emotional idea of India.

Speaking at the launch of a book on Jawaharlal Nehru's works and speeches, Singh said: "I am extremely happy that this book makes an effort to revisit Pandit Nehru. He had led this country in its volatile, formative days when we adopted democratic way of life, accommodating divergent social and political views."

The former Prime Minister said that Nehru, who was very proud of Indian heritage, "assimilated it", and harmonised them into the needs of a "new modern" India.

"A great visionary, Nehruji laid the foundation for shaping India as a modern nation state," he said.

Highlighting the works of the first Prime Minister, Singh said: "If India is recognized in the comity of nations as a vibrant democracy and, if it is considered as one of the important world powers, it was Nehru, who should be recognised as its main architect."

He said Nehru was not only a statesman of high international standing, but a great historian and literary figure too.

"With an inimitable style, and a multi-linguist, Nehru laid the foundation of the universities, academies and cultural institutions of Modern India. But for Nehru's leadership, Independent India would not have become what it is today," he said.

Taking an apparent dig at the BJP government, he said: "But unfortunately, a section of people who either do not have the patience to read history or would like to be deliberately guided by their prejudices, try their best to picture Nehru in a false light.

"But I am sure, history has a capacity to reject fake and false insinuations and put everything in proper perspective," he said.

He said the book "Who is Bharat Mata" is such an attempt to set the narrative in the right direction.

Singh said that selecting appropriate pieces from Nehruji's works, the book justifies its title "Who is Bharat Mata?"

"As this book contains a timely collection of writings by and on Pandit Jawaharlal Nehru- the leader, who shaped India and the Icon whose legacy is the subject of intense and often angry reaction today.

The book also comprises reminiscences and assessments of Nehru by some of his contemporaries and near contemporaries-among them, including Mahatma Gandhi, Bhagat Singh, Sardar Patel, Maulana Azad, Aruna Asaf Ali, Sheikh Abdullah, Ramdhari Singh Dinkar, Ali Sardar Jafri, Baldev Singh, Martin Luther King Jr, Richard Attenborough, Lee Kuan Yew and Atal Bihari Vajpayee.

"It is a book of particular relevance at a time when nationalism and the slogan of ‘Bharat Mata Ki Jai' are being misused to construct a militant and purely emotional idea of India that excludes millions of residents and citizens," Singh said attacking the BJP government.

The two time Prime Minister further said that in the pages of the carefully complied anthology-which also carries illuminating introductions by the authors Nehru emerges as a "remarkable man of ideas and action", who had an instinctive understanding of India's civilisational spirit and as a visionary with clear commitment to the promotion of scientific temper, who despite the compulsions of politics, remained a true democrat.

"His legacy continues to be of immense significance-perhaps more today than at any other time in our history," he said.

He also warned that "Nehru makes a very significant and time relevant remark on the dangers of leaderships falling into a trap and getting removed far away from the common people whom they are supposed to serve".

"In an atmosphere, when emotions are deliberately get provoked and the gullible are misled by false propaganda, misusing communication technology, this book makes a refreshing break through," Singh added.
