Japan’s Renewed Push for Clean Energy
Japan energy policy has set an ambitious target to make renewable energy account for 40-50% of its power supply by fiscal year 2040, according to a draft of its updated energy policy. The plan also outlines a significant role for nuclear energy, which is expected to provide around 20% of the country’s electricity. This clean energy push comes as Japan faces rising power demands and increasing global attention due to its reliance on imported liquefied natural gas (LNG) and Middle Eastern oil.
Currently, thermal power dominates Japan’s electricity mix, making up 68.6% in 2023. However, the draft policy projects a sharp decrease in the use of inefficient coal-fired plants, reducing thermal power’s share to 30-40% by 2040. While it does not specify the proportion of coal, gas, and oil, the document emphasizes the importance of LNG as a transitional power source. It highlights the need for long-term LNG contracts to mitigate supply risks and price fluctuations, which could arise due to geopolitical tensions.
Nuclear Power and Energy Security
Nuclear energy, once marginalized following the 2011 Fukushima disaster, is set for a revival under Japan’s new energy blueprint. The draft policy maintains the 2030 nuclear target of 20-22%, aligning it with 2040 projections. This marks a shift from earlier policies that prioritized reducing reliance on nuclear power. Instead, Japan now plans to invest in next-generation reactors to replace decommissioned plants, reflecting a renewed focus on nuclear technology.
Japan energy policy change comes amidst growing concerns over energy security, driven by global geopolitical events such as the Russia-Ukraine war. While the previous energy strategy centered on decarbonization, the new approach strikes a balance between clean energy goals and ensuring a stable power supply. Provisional forecasts predict electricity demand will rise by 12-22% from current levels by 2040, further necessitating a diversified energy mix.
Path to Net Zero and Future Challenges
Japan’s updated energy roadmap marks a critical step toward achieving carbon neutrality by 2050. However, unlike earlier plans, the revised policy omits specific targets for emerging fuels like hydrogen and ammonia. These fuels were initially projected to contribute about 1% of the energy mix by 2030, but their role in the updated policy remains unclear.
In addition to the energy draft, a joint strategy from Japan’s industry and environment ministries proposes cutting greenhouse gas emissions by 60% by 2035 and 73% by 2040. These targets form part of a linear pathway to net-zero emissions by 2050. The finalized energy policy, expected in February, will provide more clarity and be submitted to the United Nations.
Japan energy policy reflects its balancing act between meeting environmental goals, ensuring energy security, and addressing rising power needs. While ambitious, the success of these targets will hinge on technological advancements, public acceptance of nuclear power, and global energy market stability.
