再生可能エネルギーは日本エネルギー安全保障の要諦

The document positions renewable energy as a core pillar of Japan's national security, noting that the country's energy import dependency reached 87.4% in 2024. It argues that the current 7th Strategic Energy Plan is insufficient because it maintains high fossil fuel targets (30-40% by 2040) that conflict with 1.5°C climate goals. The author proposes a four-step policy framework—expanding grid capacity, accelerating permitting, expanding distributed energy, and utilizing long-term power purchase agreements—to achieve a clean energy ratio of 80% or more by 2040. This transition is estimated to potentially save up to 3.4 trillion yen in fossil fuel costs by 2035 and requires approximately 38 trillion yen in investment, which is roughly 25% of Japan's 150 trillion yen GX investment plan.
