Japan’s Low Energy Self-Sufficiency Rate and the Contribution of Renewable Energy

「Japan's energy self-sufficiency rate is currently 16.4%, an extremely low level compared with other OECD countries, and the outflow of national wealth resulting from reliance on overseas fossil fuels for approximately 80% of primary energy is a major challenge. Against this backdrop, expanding the adoption of renewable energy is becoming increasingly important as a purely domestic energy source that emits no CO2, contributes to energy independence unaffected by emergencies, and helps curb the outflow of national wealth. At present, renewable energy supports approximately 70% of Japan's self-sufficiency rate, or 12.2%.」
