The Ministry of Economy, Trade and Industry just released final numbers on the energy sector in Japan for 2011. Reporting is rather slow compared to Germany, where we already have the numbers for last year.
From that we learn that CO2 emissions from the energy sector went up 4.4% compared to 2010, and 10.8% compared to 1990, as a consequence of shutting down nuclear plants after the Fukushima accident.
Energy consumption went down by 3% compared to 2010, but was still 4.6% over 1990 levels.
Generation of nuclear energy was down by 64.5%. 2011 was not a particularly good year for nuclear energy in Japan </understatement>.
The energy sector in Japan is clearly dominated by oil. A diagram on page 10 shows that Japan got around 9,000 PetaJoule from oil, around 5,000 each from coal and gas. Japan depended to 88.8% on fossil fuel in 2011, up from 82.6% in 2010. It was only able to supply 12.4% (down from 19.1%) domestically, leaving it with a large bill for fossil fuel imports.
There is still a long way to go before renewable energy in Japan will be able to contribute a significant share. The EU goal of 20 percent by 2020 would seem to be rather difficult for Japan to duplicate </understatement>.
