Why it matters for us

At our core, JRE’s vision is based on the belief that providing renewable energy contributes to the realization of a sustainable society. This vision aims to accomplish two crucial goals:

  • ・At the global level, renewable energy generation is essential for a goal of mitigating climate change. As the energy sector accounts for around 70% of global greenhouse gas (GHG) emissions, energy systems will need to undergo a dramatic transformation toward decarbonization, which requires increased renewable energy capacity.
  • ・At the local level, renewable energy contributes to safeguarding the stability of energy supply. By providing additional sources of locally generated energy, JRE aims to strengthen the resilience of the Japanese energy market.

Our approach

JRE develops diversified renewable energy sources, including solar, onshore and offshore wind, biomass, and hydropower. In 2020 JRE’s operational capacity reached approximately 420 MW. Based on this renewable energy capacity, in the same year we displaced approximately 267,763 t-CO2 emissions. Biomass power plants contribute greatly to stable supply of renewable energy power by around-the-clock operation regardless of the weather.
We aim to contribute to the improved energy self-sufficiency of Japan and the resilience of its energy system in three different ways:

  • ・Further diversifying the energy mix, which adds resilience to the energy system should one or more energy sources be disrupted, for example in the case of accidents or natural disasters.
  • ・Contributing to Japan’s energy self-sufficiency, which reduces exposure to price volatility related to energy imports. Adding capacity to our energy system provides resilience during periods of demand spikes, such as those experienced in the height of hot or cold seasons.
  • ・Renewable energy power generation not only reduces greenhouse gas emissions, but also reduces release of other air pollutants, such as SO2, NOx and particle pollution, associated with conventional fossil fuel power generations.
