How is 100% Renewable Energy in Japan Possible by 2020? Takatoshi Kojima July, 2012 Global Energy Network Institute 12/11/2021 1

Agenda 1. Basic Information about Japan v Country Info. v Energy Info. 2. Possibility v Public Mind/Opinion, High Technology, Energy Policy 3. Renewable Energy v Wind, Solar, Geothermal, Hydropower, Biomass 4. Numerical Assumption v Installed Capacity, Generated Energy 5. Conclusion 12/11/2021 2

Japan v. Location: – Island in East Asia v. Area Size – 377, 864 km² v. Population – 126. 9 million v. Coastline – 29, 751 km(18, 486 miles) v. Climate – Mild, Four seasons 12/11/2021 3

Energy Consumption 12/11/2021 4

Electricity Mix in Japan 12/11/2021 5

Possibility Public Mind Opinion High Tech 12/11/2021 100% Renewable Energy Country Energy Policy System 6

Public Mind/Opinion v. Last year’s huge earthquake, tsunami, and nuclear disaster changed people’s mind – Opposition to re-start nuclear power plants – A lot of anti-nuclear demo in many places 12/11/2021 7

High Technology v. Japan has highest number of patents in renewable energy field – Both academic/public research and private sector – Accounts for 55% of world’s patents application 12/11/2021 8

Energy Policy/System v. Feed in tariff in Japan is among the highest in the world Feed in tariff price comparison between Japan and Germany (US cent$) Solar Wind Geothermal Hydro Biomass 12/11/2021 Suggested Prices in Japan 52. 5 28. 8 34. 1 31. 5~44. 6 17. 0~50. 8 Procurement Prices in Germany 23. 3~31. 7 4. 55~19. 5 32. 5 8. 2~16. 5 7. 8~18. 6 Japan/Germany Ratio × 1. 66~2. 25 × 1. 48~6. 33 × 1. 05 × 1. 91~7. 19 × 0. 91~6. 51 9

Wind One of the biggest trend in renewable energy industry, high possibility onshore and offshore in Japan v. Estimated Total Installed Capacity – 130 -590 GW under subsidy& Feed in tariff scenario v. Estimated Generated Power Capacity – 230 -1030 TWh/year under subsidy& Feed in tariff scenario 12/11/2021 10

Solar Japan gets ready to boost its solar energy production with strong Feed in tariff system v. Estimated Total Installed Capacity – Up to 26 GW under subsidy& Feed in tariff scenario v. Estimated Generated Power Capacity – Up to 27. 3 TWh/year under subsidy& Feed in tariff scenario 12/11/2021 11

Geothermal Japan is one of the biggest volcano country with several world’s major tectonic plates v. Estimated Total Installed Capacity – 1. 5 -4. 3 GW under subsidy& Feed in tariff scenario v. Estimated Generated Power Capacity – 9. 2 -26. 3 TWh/year under subsidy& Feed in tariff scenario 12/11/2021 12

Hydropower is more reliable and stable than intermittent sources like wind and solar v. Estimated Total Installed Capacity – 2. 7 -5. 4 GW under subsidy& Feed in tariff scenario v. Estimated Generated Power Capacity – 15. 4 -30. 7 TWh/year under subsidy& Feed in tariff scenario 12/11/2021 13

Assumption ① Millions Installed Capacity Comparison 700 600 500 400 300 200 100 0 Nationwide Installed Capacity (2011) 12/11/2021 FIT+Subsidy Scenario(future) 14

Assumption ② Billions Generated Power Comparison 1200 1000 800 600 400 200 0 Nationwide Power Demand(2011) 12/11/2021 FIT+Subsidy Scenario(future) 15

Conclusion v “Is 100% Renewable Energy in Japan possible? ” – “Yes, Japan can be 100% Renewable Energy Country. ” v “How is 100% Renewable Energy in Japan possible? ” – “The Key is Subsidy& Feed in tariff system, with variety of renewable energy resources. ” v “Is it easy to achieve the goal? ” – “No, finance and time are very severe concerns, but Japan can make it with lots of efforts. ” 12/11/2021 16
