Naturally the sustainable energy transition will actually end up costing less than continuing on the current path of fossil fuel investment and subsidies ($10 Trillion vs. $14 Trillion), and the grid will require about half the total generation (82 PetaWatt-hours / yr compared to 165 PetaWatt-hours / yr) due to the vastly greater efficiency of renewables.

The environmental savings alone warrant attention. In the US, combination trucks account for only 1% of vehicles on the road, yet produce 20% of vehicle emissions and 36% of vehicle particulate emissions. So replacing all of those with electric would make some serious headway in cleaning up our air and reducing carbon in the atmosphere
