Since May 5th 2012, Japan is running without any nuclear power. The last reactor up in Hokkaido has been shut down to undergo stresstests following the Fukushima Daiichi nuclear incident last year.
The Japanese government wants to restart at least one or two reactors but they can’t gather enough public support. It is highly likely that the reactors that seem strong enough to withhold a similar earthquake and tsunami as the 9.0 magnitude earthquake and 120ft high tsunami on March 11th 2011 will be restarted, and probably before the summer. Otherwise there will be power shortages, electricity prices will skyrocket and it will be difficult for Japan’s factories and industries to run at normal pace.
However, an increasing number of people in Japan feel that it is possible to run Japan without nuclear power. Renewable energy sources are being developed. Alternative use of energy are being considered and people are willing to rethink their energy usage to stand without nuclear power.
