Municipalities in Japan have begun to decarbonize their energy systems by introducing significant
amounts of renewable energy and building independent and decentralized energy systems. As a basis for the
discussion, we projected the balance of renewable energy supply potential and electricity demand in each of the
59 municipalities in Fukushima Prefecture. We found that the total supply of electricity in the prefecture is more
than twice as large as their demand, but that the supply is insufficient in some municipalities and that the
supply-demand balance can be improved by aggregating the municipalities into seven regional blocs.
