Decarbonising means moving away from sources of energy with extreme levels of CO2 output.
I like your thought on this, but it really is not that simple, however great it would be if it was. You get into issues of energy density very quickly, and hard industries requires lots of heat, which the conversion rate for electricity is very inefficient, necessitating other forms of energy source. It's nowhere near as simple as just "switching provider", you can't smelt steel with solar power.
For the big 5 products, steel, plastic, cement, ammonia and icantrememberthelastone, you have a bunch of processes that require energy densities that are fundamentally different to residential tier appliances etc that can be provided by solar, wind etc. And for some of these products, which are integral to worldwide economies, there really aren't feasible replacements.
