This document discusses the potential for Japan to achieve a 90% clean electricity share by 2035. Japan faces significant energy security risks as it imports nearly all the fuel for its power sector. However, with decreasing costs of solar, offshore wind, and battery technologies, it can significantly increase its clean electricity share. This transition is expected to reduce electricity costs by 6%, nearly eliminate dependence on imported LNG and coal, and dramatically cut emissions from the power sector. The document emphasizes the need for strong policies to support this transition.

This document outlines the potential for Japan to achieve a 90% clean electricity share by 2035. It highlights that declining costs of renewable energy technologies, particularly solar, offshore wind, and batteries, can lead to a 6% reduction in electricity costs and nearly eliminate dependence on imported LNG and coal. The study also asserts that Japan's power grid can remain reliable without the need for new gas capacity or coal generation. To capitalize on these significant economic, environmental, and energy security benefits, strong policies are required, including a target for 90% clean electricity by 2035 and corresponding renewable deployment goals.
