Solar Japan: some of the world’s most attractive feed-in-tariffs In the single month of March 2014 Japan approved almost as much renewable energy projects as all solar ever installed in Germany Japan’s ten regional electricity monopoly operators traditionally kept renewable energy below 1% following an unwritten rule. Tokyo Electric Power Company (TEPCO) kept renewable well below this magic 1% limit – until recently TEPCO’s renewable energy ratio was about 0.05%, slightly “greener” than Kansai, and Shikoku Electrical Power Companies with 0.03% renewables, and Chugoku Electrical Power Company with 0.02% of renewables in their energy mix. http://www.eurotechnology.com/2014/07/08/solar-japan/
