Energy Saving -Virtual Power Plant In normal situations, we contribute to a society that uses electricity smartly,
which is aimed at by the government, with the effects of VPP.
 In emergency situations, including power outage, we contribute to theimprovement of anti-disaster property of local community, by using VPP as“a power source for preventing disaster.”Disaster prevent

Renewable Energy -Regional Circular and Ecological Sphere• Potential for renewable energy inYokohama: 11%• Case of Japan, regions with high renewableenergy density are limited.
• The key point is to make link regions withhigh energy consumption with regions thatcan produce large amounts of renewableenergy.
• Promote partnerships with large areas
with great potential for renewable energy(Ex. Tohoku Region)• Model case of Regional Circular andEcological Sphere by exchange withcitizens and companies in other regions
