That kind of thinking was wrong a decade ago and is still wrong now. If we have any chance of stopping climate change we are going to have to massively decarbonise not only electricity production, but also transport and heating. That’s going to mean a massive electrification of those sectors and a huge increase in demand over decades. Putting off large fixed investment now as it wont help out immediately but will help significantly during the time that electricity demand is growing is just nonsense.
