How Much Does It Cost to Charge an Electric Vehicle? (A comparison at home and on the road, with gasoline)::Few people know what a kilowatt-hour costs them, so they don’t realize how cheap EV home charging is versus gasoline. On the road, it’s more complicated.
Unless you have a dedicated source of renewable energy that does not feed excess back into the grid, all the electricity you use has the exact same mix of fossil and renewable as the grid you’re connected to.
That is an argument for improving the fuel sources used by the grid, not an argument against switching to things that can physically be powered by renewables.
Megapacks can be used to phase out fossil plants and avoid excess electricity, thus growing the share of renewable sources in the energy mix. a 4Mwh Megapack costs about 1.4M$, ie 350$ per kwh
