- Difficulties in introducing new wind power generation facilities due to Okinawa's extreme wind speed standards.
- Unlimited and uncompensated output control of renewable energies (solar and wind) due to regulatory changes.
- High cost structure in remote islands due to small size and geographic remoteness.
- Dependence on fossil fuels for stable electricity supply.
