7. Comparison with other energies. A generation methodQuantity of annual generation (TW) The first Fukushima Nuclear Power Plant33 Photovoltaic power generation3.5 Ocean tidal power station0.6

8. Advantage and Disadvantage Advantage ・ Fuel is unnecessary. ・ It does not discharge harmful department. ・ It can perform power supply by accurate prediction. Disadvantage ・ Work to remove garbage is necessary. ・ Damage from salt breeze. ・ High cost. ・ Durability is 5-10 years. ・ A setting place is limited. 534,000,000 € Rance tidal power plant

9. Conclusion 1. I think that I should have been able to lose demerit. 2. I wish that Ocean tidal energy is developed in Japan. 3. I think that Ocean tidal energy should raise more efficiency.
