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 7: Prime Minister Narendra Modi turned emotional on Saturday when a woman beneficiary of his government's generic medicine programme told him that she had seen God in him.

Dehradun-resident Deepa Shah, who suffered paralysis in 2011, was interacting with the prime minister through video-conference on the occasion of Jan Aushadhi Diwas.

"I have not seen god, but I have seen God in you," she said, tears rolling down her eyes.

Modi was visibly emotional as the woman repeated her remark.

She also thanked the Uttarakhand chief minister and others who had helped her all along and said doctors had once told her that she cannot be cured.

"But on hearing your voice I have become better," she told Modi while profusely thanking the prime minister for his efforts to reduce the cost of medicines.

An emotional prime minister paused for a moment before telling her that it was her courage that had won over her disease and that she must carry on with the spirit.

Shah was expressing her plight and how she had suffered due to high cost of medicines after she suffered from paralysis in 2011 and has now started saving Rs 3,500 every month after benefitting from the government's low-cost generic medicines programme.

Soon after Shah rose to express her views, Modi asked her to sit and speak as he said she was uncomfortable while standing.

"You have defeated disease with your own will power. Your courage is your god and that same courage has given you the strength to emerge from such a big crisis. You should carry on this confidence in you," Modi told her.

He said some people still keep spreading rumours about generic medicines, going by their past experience, wondering how can medicines be available so cheap and that there must be something wrong with the medicine.

"But, by seeing you countrymen would gain confidence that there is nothing wrong in generic medicines. These medicines are not at all of inferior quality than any other medicine. These medicines have been certified by the best laboratories. These medicines are made in India and is 'Make in India' and are cheap," the prime minister said.

He said there is demand for generic medicines from India across the world and the government has made it mandatory for doctors to prescribe generic medicines to patients, unless necessary.

New Delhi, Mar 26: Despite repeated assurances by the Centre and state government of no shortage of food and essential services in Delhi, many daily wage earners have started fleeing the national capital on foot to return to their native villages in nearby Uttar Pradesh and other states because of the hardships being faced by them.
Most daily wage earners who are fleeing have complained that they are doing so because they will die of hunger due to lack of resources at their disposal.
"I am going to Azamgarh, my native place which is more than 800 kilometers from here. We have started walking towards our village. On the roads, if we get some vehicles then it will be all right otherwise we will continue on foot. I used to work in the construction sector but all work has stopped, we therefore have no other means to buy our rations. Atleast, food is guaranteed in our homes," Ghanshyam, a daily wage earner, told ANI here.
Rani, another daily wage earner, who was fleeing Delhi along with her family said, "Who would want to leave on foot, but what other options do we have. Our children will die of hunger, even if they are saved from the disease. That is why we are leaving."
While the government has been assuring that it will provide food and other essentials to the low-income groups, the people complained that they are yet to receive any help.
The departing of people has started despite repeated warnings by governments to prevent the influx of persons living in other states to curtail the spread of coronavirus.
Prince, who used to reside in Mongolpuri area of Delhi, said, "If we continue to stay the landlord will pester us for rent. The prices of all commodities are rising with each passing day, this way we will have nothing left to survive. We did not get any help from the government. I am, therefore, returning to Kasganj, which is close to 300 kilometres from Delhi. We will at least get food served twice a day in the village, nobody is offering us even water here."
Earlier on Tuesday, Delhi Chief Minister Arvind Kejriwal had announced Rs 5,000 for each construction worker under Construction Workers Welfare Board Fund.
Addressing a video conference here, he said, "The Delhi government will give Rs 5,000 to each construction worker as their livelihood has been affected due the outbreak of coronavirus."
He also said that the number of night shelters in the city has been increased and more food is being distributed to homeless people.
He also said that due to curfew, several people were not able to get food, and urged the public to send such people to the nearest shelters of the Delhi government, where food was being arranged.

Mar 11: In a bid to keep its flock together, the crisis-hit Madhya Pradesh Congress has decided to shift its 92 MLAs either to Jaipur or some other place.

The move comes after 22 Congress MLAs loyal to former Union minister Jyotiraditya Scindia resigned on Tuesday, pushing the 15-month-old Kamal Nath government to the brink of collapse.

"We are going to take our 92 MLAs and those supporting our Madhya Pradesh government to a hotel," a senior Congress leader said on Wednesday.

The legislators would be taken either to Jaipur or some other Congress-ruled state like Chhattisgarh, a party source said.

Apart from its own MLAs, the Congress is also keeping a close watch on four Independents who are supporting the party-led state government.

On Tuesday, 22 Congress MLAs from Madhya Pradesh resigned soon after Scindia quit the party.

The development reduced the Congress government in the state to minority.

The state Congress unit is now making all efforts to save the Kamal Nath-led government.

The BJP on Tuesday night shifted its MLAs to Manesar at Gurugram in Haryana, sources in the saffron party said.

The Congress, whose tally before the rebellion was 114, has a wafer-thin majority in the Madhya Pradesh Assembly whose current effective strength is 228.

It also has the support of four Independents, two BSP legislators and one SP MLA, but some of them are now likely to switch sides to the BJP.

The BJP has 107 seats in the state Assembly.
