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,"
