  18. National Tsing-Hua University 4. Energy Security（1/3） • Reserved electricity capacity in Taiwan decreasing continuously year by year Reserved Capacity % Projected Reserved Capacity Proj. Res. Cap. Possible Power Shortage Power Rationing at 7.4% 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 2026 4th NPP No 4th NPP Department of Engineering and System Science

  19. National Tsing-Hua University 4. Energy Security（2/3） • A comparison among nuclear fuel, coal, and natural gas in reserved quantity Reserved Quantity of Various Energy Sources in Taiwan 18 Months One fresh batch of nuclear fuel could provide 18-month electricity. Reserved Quantity (Month) 7 Days in Summer 36 Days Nuclear Fuel Coal Natural Gas Department of Engineering and System Science

  20. National Tsing-Hua University 4. Energy Security（3/3） • 98% imported energy, in lack of natural resources • Independent power grid • Insufficient base loads, leading to a higher risk of power outage • Increased instability in power supply with an increased electricity share of renewables Photo Source: https://kamonohashikamo.wordpress.com/2012/05/11/taipei-101-tower/ Department of Engineering and System Science

  22. National Tsing-Hua University 5. Statistics in 2016（2/3） * Cannot act as baseloads in the absence of large storage systems. Department of Engineering and System Science

  23. National Tsing-Hua University 5. Statistics in 2016（3/3） Projected Development of Renewable Energy Electricity Share: 4.9% in 2017 to 20%in 2025 Department of Engineering and System Science

  24. National Tsing-Hua University 6.Conclusions（1/1） • After the Fukushima nuclear accident, a lot of lessons have been learned, and they have been used to strengthen the safety of existing nuclear reactors in Taiwan. • Before the complete and sound development of renewable energy, nuclear energy is an effective solution to energy security and air pollution problems in Taiwan. • For the sustainability of a truly green society, the people and the government in Taiwan need to “choose wisely.” Photo Source: https://kamonohashikamo.wordpress.com/2012/05/11/taipei-101-tower/ Department of Engineering and System Science
