Japan Promotes the Popularization of LED Lighting with Electricity Rate Adjustment and Subsidy

After the 311 earthquake in Japan, more attention was paid to the energy crisis. Energy conservation has become a major focus of its policy development. The Japanese government believes that solving the energy problem must begin with supply (power generation) and demand (use), and will focus on the supply side. Renewable energy generation, demand, and promote the popularization of energy-saving appliances such as LED lighting.

According to a survey conducted by the Japan Institute of Energy Economics, an overall switch to LED lighting could save Japan's electricity equivalent to the power generated by 13 nuclear power plants. The potential for power saving is staggering. Among them, business-use lighting has the best power saving effect. The Japanese government currently The subsidy for LED lighting is also temporarily dominated by SMEs and public facilities.

In addition, 10 Japanese power companies belonging to different regions also jointly adjust the streetlight electricity bill to reduce the electricity cost per watt when the electricity consumption is not high. The purpose is to encourage all units to switch to LED road lighting. In 2011, Japan’s national road lighting LED The proportion is about 10%, and it is expected that the implementation of the new electricity rate will speed up the replacement of LED lighting.

In Japan, LED lighting is also combined with the development of green buildings. Buildings that were rebuilt in the disaster area after the 311 earthquake are the first to install home energy management systems and energy-saving appliances such as LED lighting, and expect to expand to other new buildings in the future. The Japanese government aims to install an energy management system for all buildings in 2025, switch to next-generation lighting such as LED or OLED in 2030, and complete zero-carbon construction in 2050.
