On 29th May 2024, METI published a renewable energy progress document of the Sixth Plan. Here we summarise our key take-aways: Solar installations must increase from about 5 GW/year now to 7. . Between 2014 and 2024, the share of solar power in electricity generation grew almost fivefold from 2% to nearly 10%, and the first half of 2025 marked the first time fossil fuels contributed less than 60% [8]. Nonetheless, surging demand, more complex system operations, and uncertainties from. . In a bold step toward redefining the global energy landscape, Japan is moving closer to a historic achievement: wirelessly transmitting solar energy from space to Earth. At the heart of this innovation is a satellite project called OHISAMA, a name which means “sun” in Japanese—a fitting symbol for. . Solar energy is Japan's most used renewable energy source, yet it still makes up a small portion of its total energy mix. China's dominance over the global solar PV supply chain is undeniably strong and undesirable. The Plan continues to emphasise the integration of energy and industrial policies. .
