Japan Targets 40-50% Renewable Energy by 2040
- Renewable growth: Japan aims for renewables to supply 40-50% of its electricity mix by 2040, doubling the 2023 share.
- Nuclear revival: Nuclear power will account for 20% of the mix, supported by next-generation reactors.
- Energy security: Long-term LNG contracts will hedge against supply disruptions during the energy transition.
The News:
Japan has unveiled a draft energy policy targeting 40-50% renewable energy in its power mix by fiscal year 2040, alongside a steady reliance on nuclear power at 20%. The planreflects a shift toward energy security while pursuing decarbonization goals amid growing geopolitical risks.
Why it matters:
Japan, the world’s second-largest LNG importer, must balance rising energy demand—expected to grow by up to 22%—with carbon reduction targets and stable supply.Key Measures:
- Renewables Expansion:
- Renewables’ share will rise from 22.9% in 2023 to 40-50% by 2040.
- Critics argue the wind power target—4-8%—is too low compared to nuclear’s 20%.
- Nuclear Power Revival:
- Nuclear power will maintain a 20-22% share, supporting 24/7 power needs for industries like data centers.
- Plans include building next-generation reactors at sites where older units are decommissioned.
- LNG as Transition Fuel:
- The government emphasizes LNG-fired power as a “realistic” transition measure.
- Long-term LNG contracts will help mitigate price spikes and supply risks.

Broader Climate Goals:
Japan’s draft energy plan aligns with its greenhouse gas reduction pathway:
- 60% cut by 2035.
- 73% cut by 2040.
- Net-zero emissions by 2050.
The final greenhouse gas strategy will be submitted to the UN in February.
What’s next:
Japan’s energy plan will be finalized and approved by the cabinet early next year. The strategy signals a pragmatic approach to balancing clean energy investments, nuclear resurgence, and energy security amid rising demand.
