2. Power Mix before Fukushima

After Oil Crisis (1973,1979)  Away from Oil : Development of Nuclear and Renewables  High-efficiency power technology development

Kyoto Protocol (1997) : CO2 emissions 6% cut from 1990 level
Law of Alternative Energy (2009) : Non-fossil power portfolio regulation
“Basic Energy Plan” (June 2010) :

13% 29% LNG-fired Oil-fired Coal-fired Nuclear Renewable 11% 25% 53% 29% 2% 7% 21% 9% Power mix ▲30% ▲6%（～2012） CO2 emissions （compared to1990） 2030 2009

Realization of a society without nuclear power

→ Mobilize all policy resources to enable zero operation of nuclear power plants in the 2030’s

3-2 Opposition to the “Strategy” and Reaction of the Cabinet 9 The Cabinet in disarray

“Strategy” failed to be endorsed by the Cabinet.
Retardation of formulating new “Basic Energy Plan”

Uncertainty of Japan's energy policy Oppositions from Keidanren and other organizations

Jeopardizes stable power supply
Inconsistency with economic growth strategy
Loss of contribution opportunities to peacefully use of nuclear

energy worldwide Concerns from various countries

USA: Nuclear proliferation problems
France: Nowhere to go for the fuel reprocessed in France
