Japan’s Renewable-Energy Potential, Municipality by Municipality
A public comparison tool for estimated renewable-energy potential across Japan’s 1,741 municipalities, broken down by technology and region.
- For
- Residents and planners comparing local renewable-energy options
- Worth noticing
- It separates electricity (MW and MWh/year) from heat (GJ/year) and flags that summed electricity estimates mix survey years.
Field notes
Municipality and prefecture tables break the estimates out by eight electricity categories and two heat categories, with sortable comparison columns and navigation to municipality lookup. The page lists which municipalities have nonzero estimates and shows leading prefectures for each technology. It explicitly warns that electricity totals combine estimates from different years, while heat is reported separately in GJ/year; the underlying figures are identified as Ministry of the Environment REPOS data.
