Reply #3: Electricity is source neutral. Not a very good example.

I would remove all examples of electricity from your post.

The coffee pot doesn't care if the electricty coming down the wire was made by hydrocarbons, wind, solar, geothermal, nuclear, tidal, etc.

Of all forms of energy electricity is the easiest one "fixed". A kWh is a kWh regardless of where it comes from.

Heating is slightly harder but easily solved.
A magnitude harder is transportation. You will never see an battery powered cargo ship, or passenger jet.
The hardest of all is industrial applications (coal for steel, oil for plastics, etc).
