Tokyo, April 3 (Jiji Press)–Japan’s environment ministry plans to visualize how far electricity generation from renewable sources has progressed in each municipality, and is even considering creating rankings by the degree of progress, Jiji Press learned on Saturday.
Data such as goals and results of renewable energy use in municipalities as well as the potential amounts of electricity that can be generated from renewable sources will be compiled in a form that can be viewed at a glance. The data will be made public in late fiscal 2021 at the earliest.
For each type of renewable energy sources, the ministry calculates the theoretical amount of electricity that exists, using data such as the size of space available for installing power generation equipment, wind speed and volume of river flow.
The ministry then estimates the potential amount of renewable electricity, factoring in natural conditions, legal restrictions, project feasibility and other factors.
The ministry has already worked out the potential amount in each municipality for wind power, water power and geothermal power. These data are available on the ministry’s website.
For solar power, the ministry will complete municipality-by-municipality calculations in the current fiscal year ending in March 2022, so that it can estimate the potential amount in each municipality.
According to the ministry, the amount of electricity that can be produced from renewable sources across Japan is estimated at a maximum of 2.6 trillion kilowatts per year, about twice as much as the country’s annual electricity supply.
Believing that there still are a lot more places where renewable power generation can be introduced, such as building rooftops and abandoned farmland, the ministry plans to further promote electricity generation from renewable sources.
