Even so, power inverter accounts for only 0.6% of the electricity supply.

Apart from the high cost of solar, wind and other renewable energy sources is vulnerable to weather, the output power inverter is very unstable.

Taketoyo solar power station is a power inverter plant of Chubu Electric Power Inverter, covers an area of ​​140,000 square meters, about the equivalent of 20 standard football field, equipped with a 1.3 m long, 1 meter wide, nearly 40,000 solar panels installed capacity of 7,500 kilowatts, annual generation capacity of 7.3 million kilowatts, but still not as an installed capacity of one million kilowatts of thermal power stations or nuclear power inverter capacity of eight hours.

Acting Director of Taketoyo solar power stations, Hori said Ryuji any kind of energy has advantages and disadvantages, power converter can reduce greenhouse gas emissions, but require a large area of ​​land, the high cost of operation is low, power converter is not stable, it is difficult to become the basis of power.

Nuclear power plant restarted difficult.

Fukushima Daiichi nuclear power plant accident broke Japan's "safety myth".

 For a time, people talk about the mere mention of the "core", "anti-nuclear power inverter with charger in the country, the public distrust of nuclear power is unprecedented.

But as time goes on, the Japanese society views on nuclear power inverter with charger is becoming more and more rational appeal to restart the nuclear power's voice began to appear, but the contradiction remains entrenched polarization of public opinion, serious opposition.

Nevertheless, for practical reasons, the Japanese government and power companies try to restart the nuclear power inverter with charger has never stopped.

 June 16, 2012, when he was the Prime Minister of Japan Yoshihiko Noda announced the restart in the 3rd and the 4th units of the Oi nuclear power plant in Fukui Prefecture, restart the Fukushima nuclear accident after the first nuclear power plant.

 Since then, the major power companies have been ready to work for a further restart.
