A new study led by Tohoku University has revealed that rooftop solar panels, when combined with electric vehicles (EVs) as batteries, could supply 85% of Japan's electricity demand and reduce carbon dioxide emissions by 87%. The research provides a promising pathway for Japan's local governments to achieve carbon neutrality by taking advantage of existing infrastructure—rooftops and vehicles—rather than relying solely on large-scale energy systems.
