It is not that the government thinks nuclea is green as much as they know who gives the biggest donations and more importantly which industries would cost the most to shut down. Any government who tries to remove the nuclear industry has to plan for a very large clean up bill.
I stated before that the price of electricity in Japan from nuclear includes an advanced payment for the de-commissioning. It was announced last week that Japan will plan for 22% of energy to be nuclear based in the future. Even though at present no reactors are working they are committed to re-starting many of them with a protest at each site and each local authority saying they would rather keep them stopped. The government continues on a path of least pressure for government funds. They can not afford to shut down all the reactors.
This is the case with UK as well where not only reactors but bombs have a clean up cost which hurts the government and the people paying taxed. It is a debt left over since its inception and will not go away with the democratic process we have all considered progress.
As far as I am aware Robert charges a large proportion of his journeys through solar. For him it is a much greener process. An we can assume this would be the case for many others but obviously not all people. I do not drive a car very often. I walk, ride a bike, take a train for most of my journeys. For me that is the best option but once again people have to assess there own needs to pick the more appropriate lifestyle for themselves. It can not and should not be a universal rule for everyone.
