BEYOND THE ATOM: The shutting down of the last operating nuclear power reactor has only added urgency to calls for a green energy revolution. The picture shows the Ikata wind farm at the Sadamisaki Peninsula near the Ikata nuclear power plant.

Environmentalists say the shutting down of all 54 reactors in the country is an unprecedented opportunity to find new sustainable sources of energy.

This week Japan begins a bold experiment in energy use that no one had thought possible — until the Fukushima Daiichi power plant suffered a triple meltdown just over a year ago.

On Saturday, when the Hokkaido electric power company shut down the No.3 reactor at its Tomari plant for maintenance, the world's third-largest economy will be without a single working nuclear reactor for the first time for almost 50 years.

The closure of the last of Japan's 54 reactors marks a dramatic shift in energy policy, but while campaigners prepare to celebrate, the nationwide nuclear blackout comes with significant economic and environmental risks attached.

The crisis at Fukushima sparked by last year's deadly earthquake and tsunami forced Japan into a fundamental rethink of its relationship with nuclear power.

The Tomari shutdown comes as Japan braces itself for a long, humid summer that will have tens of millions of people reaching for the controls of their air conditioners, raising the risk of power cuts and yet more disruption for the country's ailing manufacturers.

In a report released this week, the government's national policy unit projected a five per cent power shortage for Tokyo, while power companies predict a 16 per cent power shortfall in western Japan, which includes the major industrial city of Osaka.

“I have to say we are facing the risk of a very severe electricity shortage,” the Economy, Trade And Industry Minister, Yukio Edano, said, adding that the extra cost of importing fuel for use in thermal power stations could be passed on to individual consumers though higher electricity bills.

Before the March 11 disaster, Japan relied on nuclear power for about 30 per cent of its electricity, and there were plans to increase its share to more than 50 per cent by 2030 with the construction of new reactors.

Nuclear vision ends

The release of huge quantities of radiation into the air and sea, the contamination of the food and water supply and the evacuation of tens of thousands of residents mean that the vision of a nuclear-dominant, low-carbon future lies in ruins.

Over the past 14 months, dozens of nuclear reactors not directly affected by the tsunami have gone offline to undergo regular maintenance and safety checks, while utilities have turned to coal, oil and gas-fired power plants to keep industry and households supplied with electricity — imports that contribute to Japan's first trade deficit for more than 30 years last year.

Japan, already the world's biggest importer of liquefied natural gas, bought record amounts of LNG last year to replace nuclear energy. The international energy agency estimates the closure of all nuclear plants will increase Japanese demand for oil to 4.5m barrels a day, at an additional cost of about $100m a day.

Last-ditch attempts by the Prime Minister, Yoshihiko Noda, to win support for the early restart of two reactors at Oi power plant in western Japan have failed amid a hardening of public opposition to nuclear power.

None of Japan's idle reactors will be permitted to go back online until they pass stringent “stress tests” — simulations designed to test their ability to withstand catastrophic events such as the 14-metre tsunami that knocked out Fukushima Daiichi's backup power supply, and sparked the world's worst nuclear accident since Chernobyl.

While some experts have criticised the two-stage stress tests as inadequate, an immediate return to even a limited amount of nuclear power now seems impossible.

Restart, says business lobby

Residents' approval isn't legally required for restarts, but Noda is unlikely to risk the possible political fallout from ignoring local opinion: in a recent poll by Kyodo News, 59.5 per cent are opposed to restarting the Oi nuclear power plant in the Fukui prefecture, while 26.7 per cent support it.

Leading the push to restart the reactors is Keidanren, Japan's influential business lobby. In a recent survey, 71 per cent of manufacturers said power shortages could force them to cut production, while 96 per cent said that the additional spectre of higher electricity bills would hit earnings.

The Japan Institute for Energy Economics has warned that keeping nuclear reactors mothballed could limit GDP growth to just 0.1 per cent this year, as manufacturers cut back production while paying higher prices for crude.

Critics of the nuclear shutdown have also highlighted the impact more fossil fuel power generation will have on Japan's climate change commitments. Even big investors in renewables, such as the Softbank chief executive Masayoshi Son, concede it will take time for them to have any real impact on the country's energy mix.

They will be buoyed by a new Environment Ministry panel's assertion that Japan can still reduce its greenhouse gas emissions by 25 per cent by 2030 from 1990 levels without nuclear, through energy saving and the quicker adoption of renewables, which it hopes will account for between 25 per cent and 35 per cent of total power generation by 2030.

“If Japan has the motivation, it can do this, too,” said Sei Kato, Deputy Director of the Environment Ministry's low carbon society promotion office. “We have the technological know-how.” Short-term risks aside, environmental groups say Saturday's shutdown is an unprecedented opportunity for Japan to wean itself off nuclear power.

“This is a turning point for Japan, and a huge opportunity for it to move towards the sustainable energy future its people demand,” Greenpeace said in its advanced energy revolution report. “With an abundance of renewable energy resources and top-class technology, Japan can easily become a renewable energy leader, while simultaneously ending its reliance on risky and expensive nuclear technology.” On Tuesday (May 1), office workers made their contribution with the start, one month earlier than usual, of the annual “cool biz” drive to reduce energy use. But swapping suits and ties for short-sleeved shirts, and turning down air conditioners will be easy for as long as Japan enjoys mild spring temperatures. The biggest test of their post-Fukushima resolve has yet to come. — © Guardian Newspapers Limited, 2012

India situation is different from Japan. Japan is already a developed
country but India is developing country. For future India demand for
power will increases and that cannot be fulfilled by single source of
Energy. Instead India has to diversify its energy resources as reiterated by Prime Minister. Also India has vast resource of thorium
which is proposed to be used In IIIrd nuclear stage and fissile
materials required for this stage is by product of Ist and IInd
nuclear stage and for Ist nuclear stage we require uranium. So we have
keep option open for nuclear , renewable and non renewable energy

Finally, the govt of Japan has took a historic decision to halt the generation of nuclear power. However, the question of shortfall in energy supply is daunting the industrialists. In the near future it will be interesting to see how Japan responds to meet the energy demand through renewable sources and set an example to the world. But, at present the energy demand has to be invariably addressed through non-renewable energy sources which causes threat to environment in the era of climate change.

wind farms disrupt the flow of air and cause alterations in the atmosphere with many
adverse effects.
we are taking steps without knowing which path we're on.

It appears to me that the cluster of towers and blades of the wind-turbines (such as at Ikata, Japan shown in the photo accompanying the article) too may not withstand an, earthquake, gale or a tsunami without causing collateral damage to the electric grid and life and limbs of any population living nearby. On another note, take for example, the case of wind-turbine farms at Kanyakumari District. As population in India increases, pressure on land for construction of housing, factories, offices, airports, and other types of buildings would also increase. In such a scenario, would construction of high-rise structures be prohibited on the land upstream as well as downstream of the wind-turbine farm?

The govt.of Japan respected the feeling of Japanese people. nuclear free world is essential for sustainbility. mnc lobby is against this historic Indian govt.ready to hear the feeling of the people of India or serve the interest of American nuclear technology lobby. we want to save the world at any cost.we are not only consumer but sensible creature. follow the Japanese path and make the world nuclear free.
