However, times have changed, and the alternatives to nuclear power have performed better than almost anyone expected. Looking back on my first book, ‘Seeing Green’, from 1984, I was fiercely critical of nuclear power, but have to admit that my advocacy of renewables (as the principal alternative) was somewhat muted. Apart from a few visionaries in the early 1980s, no one really thought that renewables would be capable of substituting for the use of all fossil fuels and all nuclear at any point in the near future. Happily, there is no longer any doubt about the viability of that alternative. In 2020, Stanford University issued a collection of 56 peer-reviewed journal articles, from 18 independent research groups, supporting the idea that all the energy required for electricity, transport, heating and cooling, and all industrial purposes, can be supplied reliably with 100% (or near 100%) renewable energy. The solutions involve transitioning ASAP to 100% renewable wind – water – solar (WWS), energy efficiency and energy storage.
