Electrical generation is a small part of the problem.

Electricity generation takes up less than half of global energy consumption, I think the figure is 30-40%.

This means most fossil fuels are burned for purposes other than generating electricity, and even if 100% of electricity generation was carbon-free you would still have a ton of fossil fuel consumption, things like heating, transportation, etc.

Transitioning all of that energy consumption to electricity is a huge feat, AND you need a f-ton more electricity generation, transportation, and storage, and of course it needs to be carbon free otherwise the problem is just made worse by the inherent inefficiencies.
