In theory, yes. In practice, it doesn't work that way. Compare the
efficiency of a car engine with the efficiency of an electric car
(end-to-end).



and the grid allows power to be sourced from a variety of different
methods depending on
availability and demand.

Again, only in theory. In practice the source is gas, oil and coal.

Theory is great, the real world is different.

If nothing else it moves the emissions
from 'everywhere' to a few locations,
so it has the potential for huge
improvements in air quality in built-up areas.

Which is 95% of us.
