Japan’s New Energy Strategy: Nuclear Power and Renewables Key to Future Growth

Japan is set to implement a new energy strategy to meet rising electricity demand while advancing its decarbonisation efforts. A government-backed expert panel has endorsed plans to boost nuclear power and expand renewable energy sources, aiming for up to 50% renewable energy by 2040. Nuclear power is expected to contribute 20% of the country’s energy supply, reversing previous phase-out policies enacted after the 2011 Fukushima disaster. These changes are designed to enhance energy security and help Japan achieve its net-zero emissions target by 2050.

Key Goals in the Draft Policy

According to the Industry Ministry’s proposed energy policy, renewables will become Japan’s primary energy source, with a goal of reaching 40–50% of the energy mix by 2040. Meanwhile, nuclear energy will provide stable, low-carbon power. The plan includes restarting reactors that meet updated safety regulations and constructing next-generation reactors at decommissioned sites.

To meet the growing energy demands of data centers and semiconductor factories, Japan aims to significantly reduce coal usage and invest in advanced solar technologies and portable energy solutions. However, experts have raised concerns about the feasibility of these ambitious targets due to slow progress in reactor restarts and regulatory approvals.

Challenges in Achieving Nuclear Targets

Experts have pointed out that restarting all 33 operational reactors in Japan will be a major challenge to meet the proposed nuclear energy targets. Industry Minister Yoji Muto emphasized the need for decarbonised energy security to support economic growth. However, critics have noted that the draft policy lacks specific timelines for phasing out fossil fuels and places heavy reliance on reducing renewable energy costs.

The draft plan, which will undergo public consultation and Cabinet review in March, reflects Japan’s dual approach of utilizing nuclear power and renewables to meet its energy and decarbonisation goals.
