Power shortage forced Japan to take measures to save electricity

In the face of rising electricity bills and severe power supply conditions, at the end of 2022, the Japanese government required government agencies, commercial institutions and households across the country to take effective measures to save electricity by March 31, 2023. However, Japanese experts said that it is difficult to determine whether the power saving measures can achieve great results. Developing renewable energy is the fundamental way to deal with the problem of power shortage.

A Japanese official said that his colleagues used to wear only a suit coat or even a shirt in the office in winter, but now because the temperature in the room is relatively low, the staff in the office area wear more clothes than usual. Citizens have also taken many measures to save electricity at home, such as letting two children share a bedroom, opening an air conditioner for heating, or purchasing power-saving household appliances. Their goal is to reduce electricity consumption by 15% compared with that before the East Japan earthquake.

After the Japanese earthquake in 2011, the power supply structure in Japan has undergone a major change, with nuclear power accounting for 30% of the total power supply, gradually decreasing to about 10%; Thermal power generation increased to about 70%. At the same time, Japan's dependence on imported energy has further increased. In 2022, the instability of the international situation and the sharp decline of the yen exchange rate led to the rising price of energy imported by Japan from the international market, and also increased the uncertainty of supply. This has caused all circles in Japan to worry about the power problem.

SUOHER heat pump can use renewable energy in nature with high efficiency, which fully conforms to the global trend of developing clean energy in the future.

A Japanese professor believed that although the government announced that it would grant subsidies in January 2023, and the electricity bill might fall in the short term, it is expected that the electricity company will raise the electricity bill by a greater margin, so Japan should develop renewable energy.
