Yes, you're right, my mistake. I expressed myself wrong (thought one think, wrote another...). We can live on renewables + nuclear (if we get there, which would be a monumental task - both politically and in terms of building necessary infrastructure, not to mention electrifying pretty much everything that now burns fuel), but definitely not on renewables alone. And this transition needs to be started ASAP.

The final comparisons of stacks were against electrified and reduced consumption (author started by pointing out how to reduce overall energy use to little more than 50% of the base value). There are many easy tricks that can help with this reduction - like better home insulation, keeping heating few degrees lower, using heat pumps for air conditioning, etc. - that don't mean one has to live without hot water & computers. But people need to start implementing those measures if we are to have any chance in transitioning to a sustainable energy economy.
