Japan has paid more attention to the energy crisis after the 311 earthquake, and energy conservation has become a major focus in its policy development. The Japanese government believes that solving energy problems must start from both supply (power generation) and demand (use), and will focus on development in terms of supply. Renewable energy power generation, on the demand side, promotes the popularization of energy-saving appliances such as LED lighting.
Ten power companies in different parts of Japan have also jointly adjusted the street lamp electricity bill to reduce the electricity cost per watt when the power consumption is not high. The purpose is to encourage all units to switch to LED road lighting. In 2011, the proportion of national road lighting LEDs in Japan was about 10%, expecting to speed up the replacement of LED lighting after the implementation of the new electricity bill.
According to a survey conducted by a research institute, the comprehensive conversion to LED lighting can save electricity equivalent to 13 nuclear power plants in Japan, and the potential for power saving is amazing. Among them, the energy-saving effect of business lighting is the best, and the Japanese government is currently lighting LED lighting. The subsidies are also mainly for SMEs and public facilities.
The LED lighting in Japan is also combined with the development of green buildings. Buildings reconstructed in the disaster areas after the 311 earthquake are the first to install energy-saving appliances such as home energy management systems and LED lighting, and expect to expand to other new buildings in the future. The Japanese government aims to install energy management systems for all buildings in 2025, and to switch to next-generation lighting such as LEDs or OLEDs in 2030, and to complete zero-carbon construction in 2050.
