What a terrible take.
First off, unironically yes on account of higher efficiency in electric engines over combustion engines.
Second, what grids still run on 100% coal? And why would they keep doing that long-term, given that coal is just shit on its own merits?
32% coal vs 39% renewables, with natural gas making up the majority of the remainder - https://www.eia.gov/state/?sid=CO#tabs-4
