While your statement is true your graph is misleading for two reasons. 1) comparison of spent energy for fossil fuels vs electricity is not a good way to do it because electric motors use less for the same output. Compare kWh per 100km for an ICE car and EV. Electrification will lead to a drop simply because of this 2) the graph is global, we have seen energy consumption go down in the developed world. E.g. the EU now uses less electricity than 20 years ago. | ||||||||||||||||||||||||||||||||

> comparison of spent energy for fossil fuels vs electricity is not a good way to do it because electric motors use less for the same output. Compare kWh per 100km for an ICE car and EV. Electrification will lead to a drop simply because of this Yes but there are losses in generating electricity, and in transmitting it as well. If you only measure from energy in your car's battery to motion you're right, but I don't think that's a useful measure. | ||||||||||||||||||||||||||||||||

I think 2) is a lot more complicated to the point statements like that are misleading. Take a look Graph of energy consumption of China which is about double the US: https://ourworldindata.org/profile/energy/china The energy consumption of the United States has flat lined: https://ourworldindata.org/profile/energy/united-states One can argue that the US and Europe have maintained a low energy consumption by de-indusrializing and having China produce all the energy (largely with coal!) to manufacture their goods instead of manufacturing it themselves. 1) Is a lot more complicated as well. A simple ICE vs EV comparison ignores electric grid generation efficiency and transmission losses as well as the massive energy cost of manufacturing the battery. | ||||||||||||||||||||||||||||||||
