Chiba University and the Institute for Environmental Energy Policy are conducting research on "permanent zones" to understand the actual supply of renewable energy by municipality in Japan, and this is the 12th year of the "Permanent Zone 2017 Edition Report". Calligraphy "has been published. A "permanent zone" is an area that can produce the energy and food needed to continue living.

 According to the report, the amount of solar power generated increased by 2016% in FY2 (compared to the previous year), but the growth rate has slowed compared to the increase of 2014% in FY6 and the increase of 2015% in FY4.On the other hand, among renewable energy power generation other than solar power, wind power generation and biomass power generation increased by 12% (compared to the previous year), geothermal power generation decreased by 5%, and small hydropower generation remained almost unchanged.In addition, the supply of renewable energy heat has been almost flat.As a result of the increase in renewable energy power supply, domestic renewable energy supply has increased about 2017 times in the five years until March 3.

 The number of municipalities (energy permanent zones) that produce renewable energy that exceeds the energy demand for civilian and agricultural water (energy demand for continuing to live) in the region has increased to 11.In addition, the number of municipalities (permanent power zones) that generate renewable energy power that exceeds the demand for electricity for civilian and agricultural water in the region increased by 82 to 21.

 The number of prefectures where the energy supply from renewable energy exceeds 10% of the energy demand for civilian and agricultural water in the region increased to 2017 prefectures as of March 3 (33 prefectures as of March 2013).Of these, 3 prefectures exceed 8%.

 There are 100 municipalities whose food self-sufficiency rate exceeds 566%. Of the 100 municipalities that are 82% energy permanent zones, 42 have a food self-sufficiency rate of over 100%.These cities, towns and villages can be said to be truly "permanent zones."
