I find it very interesting (genuinely!) that your reaction to the linked article was to conclude (I think?) that it will be impossible to mitigate climate change.
Is your position, broadly stated, something like "because these days many more things require electricity than at some point in the past, our demand for electricity will be too high, and this will prevent us from mitigating climate change"?
In a way, but I am pointing out how many new things now require electricity/power where in the past they did not. There are many items that were manual, another example(s) are kitchen items, like powered can openers, knife sharpeners, food processors, etc. Moving back to manual items for these is like getting low hanging fruit. Will help a bit when matched against the number of people using them.
For climate change we need to change our habits, but many people cannot even walk/bike to the store that is a half a mile (~1km) away, instead they drive.
Based upon that alone, unless we are forced to change, we never will until cities are under water.
I think one way to force a change is to get gas prices high. But even doing that, with high rents in the cities, many people cannot afford to live in a walkable area. So in essence, our children, grandchildren are pretty much screwed.
But at least there are some easy changes people can make.
