Release of the 2009 Energy Sustainable Zone Estimates (Quick Estimation)

The Kurasaka Research Center at Chiba University and the NPO Institute for Sustainable Energy Politics in their joint study Energy Sustainable Zone, announced the present status and progress of the regional natural energy supply in Japan. In the 2009 edition, based on actual values as of the end of March 2009, the supply ratio of natural energy is estimated by prefecture and municipality.

The summary of the 2009 edition is as follows:
• Municipalities to be a 100% energy sustainable zone increased by five cities and towns, resulting in 57, in comparison with the FY 2008 totals.
• The renewable energy supply in Japan increased by 2.3% between March 2008 and March 2009.
• Solar photovoltaic sources, wind power generation, and biomass power generation increased by 10% or more; however, geothermal power generation decreased.
• Renewable energy sources that do not show increasing trends (small-scale hydropower, geothermal, and solar heating generation) accounted for 77% of the renewable energy supply.
• In seven prefectures, renewable energy supply exceeds 10% of the regional energy demands for commercial plus agricultural uses.
• Toyama Prefecture has the highest renewable energy supply per area.
