Every home in Japan now has access to a novel electrical system.
The Tokyo administration has announced a plan to install solar roof panels on every new house built beginning in 2025 to cut carbon emissions from the household energy sector. On residential buildings less than 2,000 square meters (215,000 square feet), construction companies will be required to install solar panels and other renewable energy sources.
The first of its kind in Japan, the directive aims to cut the city’s carbon emissions in half by 2030. Under the current rate of 100,000 yen ($728) per 1 KW and the utility bill exemption, the government estimates that the cost of a 4 kW power installation, which is 980,000 yen ($7,200), can be recouped within six years.
The Tokyo government estimates that by 2050, about half of the old buildings will be replaced by new ones, and 70% of the old buildings are residential. According to Statista data, a total of 800,000 to 900,000 new buildings will be built annually in Japan between 2012 and 2021. The world of contracting is dominated by major contractors known as Super Zenecon.
Japan has pledged to become carbon neutral by 2050, making it the fifth-largest emitter of carbon dioxide in the world. At the moment, France is one of the nations that have made it a legal requirement to use solar energy.
