This is the conclusion of an international group of scientists systematically working through the counter-arguments of a pro-nuclear group. They come from the Karlsruhe Institute of Technology in Germany, the South African Council for Scientific and Industrial Research, Lappeenranta University of Technology in Finland, Delft University of Technology in the Netherlands and Aalborg University in Denmark.
The image shows primary energy consumption (grey and green) versus useful energy services (blue) in today’s versus tomorrow’s energy system (from the source article and references therein), and shows the importance of energy efficiency in renewable supply.
Hardly surprising, but I agree with this team. Yesterday afternoon, for a while, solar energy was the single biggest source of power supply to London.
