Renewable energy ... the future of Japan?

In the city "Vutoba" which are now all empty, inside the evacuation zone surrounding the Fukushima Daiichi plant, plate stands at the entrance to a main street that read "Nuclear energy is the energy of a bright future." But today, while workers continue their struggle to contain the radioactive leak at the station, which forced Japan lacks energy resources to re-examine the commitment to nuclear power, and began searching for other alternatives. In this context, the new policy in the field of energy, Japanese Prime Minister, "Naoto Kan," the explanation outlined this week, the importance of solar and wind power, but require costly investments in addition to creativity and innovation.



In a speech this week, he noted, "was" to a number of specific objectives, for example where he said that solar energy should be mandated by 2020, a third of what it cost today. By 2030, the cost should be reduced to one sixth the current cost. Within ten years or so, it should be a source of 20 percent of Japan's total energy supply from renewable resources, double the current share or more. He said, "was" also said that about 10 million building should be available on the solar panels by 2030.



And urges "was" of its citizens on the rational use of energy, pointing out that he wants to be the program of Japan's nuclear safer and smaller; is because he knows that all these steps will require a radical change, and evidence of this use of the word "challenge" at least seven times During his explanation of the principles of Japan's policy in the new energy sector.




Before the incident, Fukushima, which is the most serious nuclear crisis in a quarter century, Japan had spent decades in promoting and cheering of the benefits of atomic energy; where nuclear plants provide 30 percent of the country's energy needs, with plans to raise this percentage to 50 percent by 2030. However, Fukushima accident, caused by the earthquake atheist th March which hit Japan and the devastating tsunami that followed, the reason for the large-scale demonstrations hostile to the use of nuclear energy and national debate about the security of nuclear plants. But government officials insist that the country will not abandon nuclear energy in full, and there are many reasons that explain this situation, in fact, and the fact that nuclear energy is reduced Japan's imports of fossil fuels. It also does not produce second Oxidalkrbun and, above cheap.



However, the atomic energy site in the future of Japan has changed significantly. That Japan is unlikely to build reactors, a new, as announced, "was" this week in an interview with the newspaper "Financial Times" British, which is another indication of a clear indication that the country had been taken away from the goals of nuclear energy for pre-atheist tenth of March.



It is worth mentioning that only 17 of the 54 Japanese reactors produce energy now, as it closed 22 of them for inspections planned or unplanned, according to World Nuclear Association. In addition, he was arrested two reactors operating in two earthquake-prone area southwest of Tokyo by order of government; this while stopped nine reactors automatically day of the earthquake, as it is designed to do, and still out today. The four reactors in the affected station "Fukushima Daichi," it will never be used again to generate electric power.




Because of the crisis Fukushima, had registered the Tokyo Electric Power Company - which produces 27 percent of the power of the country - a significant shortfall in production. In order to reduce electricity consumption and avoid blackouts during the summer months known as a rise in consumption, called on the government to reduce electricity use by 15 percent from the first of the month of July. However, it is noted in advance that the escalators in subway stations in Tokyo does not operate. Also keep shopping at the level of the dim lighting; and companies do not run Mkevadtha air to the maximum. And wants "was" in that some of these changes long term, as called for "a new culture of consumption of electricity."



Although the Prime Minister identified new targets for energy, it is not clear after the details of how it will achieve these objectives, and in particular how Japan will cut the cost of solar power drastically. Only the Japanese Ministry of Economy, Trade and Industry, the cost of solar energy production is 60 cents per kilowatt hour, while the cost of nuclear power 6 to 8 cents per kilowatt hour. The fact that Japan in order to achieve the goal of reducing the price, the solar energy should cost about 10 cents per kilowatt hour by 2030.



The proposed legislation would force utility companies to buy electricity from large-scale projects for solar energy; but Japan also hopes to lead the progress and development of technology to reduce costs. However, the fears within the government than the issue price; where indicated and the Ministry of Economy, in a report released in 2010, that some sources of renewable energy is "unstable, and stations can be established only in a limited number of areas because the conditions required in terms of topography, etc. that. "





 
In this context, "said Ken Koyama," Director of the Institute of Energy Economics in Tokyo: "I think it is good to specify an ambitious vision for renewable energy"; but to rely on nuclear energy, without specifying how to reduce the price first "would be dangerous," he says, adding If it were to cover all surfaces in the area of ​​central Tokyo, solar panels, the amount of energy that will be produced will equal the amount produced by one nuclear reactor.
