We are very much reaching limits in the field of energy. This seems to mean that we ending up taking more and more risks, so that there is a greater risk of things going wrong. At the same time, the world’s population is so high that without a good deal of external energy, we cannot provide basic necessities for nearly 7 billion people. So we almost have no choice but choose energy sources which are almost out of our reach.
With the problems with nuclear energy in Japan, the question arises as to what would happen if we just discontinued nuclear electricity. How big an impact would this have?
Since many plants are near the end of their originally planned lived, such discontinuation could come simply by not extending any more licenses, and not permitting new facilities. Since such decisions are made by each country, it is highly unlikely that a coordinated decision in any direction might be made. In fact, what we are likely to see is a mixture of different decisions. I thought it might be helpful to have some numbers to look at, to get an idea as to what role nuclear currently plays in generation around the world. I also discuss some other implications–for example, for electric cars. Continue reading
