The entirety of the global electricity sector generates roughly as much power as liquid transport fuels. Run the math: switching all transport from internal combustion to electric would necessitate a doubling of humanity’s capacity to generate electricity. Again, hydro and nuclear couldn’t help, so that ninefold increase in solar and wind is now a twenty-fold increase. Nor are you even remotely done. You now need absolutely massive transmission capacity to link the locations where wind and solar systems can generate power to where that power would ultimately be consumed.
