They outsource energy to remote power plants and outsource pollution
and other downsides to other countries...
There are serious technical mistakes in those sentences.

Nice comparison, and correct as for as it goes.
No dispute with any of that, comparing last-step efficiencies of the two
formats.
It's not just "last step." Read the article down to the part about
replacing gasoline with coal, or with natural gas. ""Even if the grid
were entirely fueled by coal, 31% less energy would be needed to charge
EVs than to fuel gasoline cars. If EVs were charged by natural gas, the
total energy demand for highway transportation would fall by nearly
half. Add in hydropower or other renewables, and the result gets even
better, saving up to three-fourths of the energy currently used by
gasoline-powered vehicles,"
