It's infinite as long as we have energy. You can create it at home if you feel inclinedElectric motors are far superior to ICE in the majority of applications. On top of that they are simple, efficient, recyclable and almost maintenance free.The only reason we didn't have them in the past was the difficulty storing electricity. Thats not really an issue these days.Did you mourn the passing of steam trains? The thermal efficiency of standard diesel car engine is around 43% the rest is lost in heat and friction.For an EV from the generation of the electricity to powering the car its around 45% the rest is losses in transmission and to power charging equipment.So again what is the point of EV cars when they offer no measurable increase in efficiency over an ICE engine.Ahh, so you're measuring EV efficiency from the point of electricity generation, but diesel efficiency from the point it's already in the tank No wonder you can't see the EV benefit - you're comparison is massively skewed !EVTransmission losses : 10%Car energy efficiency : 75%+DieselProduction losses : 15%Electricity requirements to mine oil : 3 kWh per litreElectricity requirements to refine diesel : 0.15kWh per litreProduction Pollution : Major air pollutants that harm human health and damage the environmentTransport loses : 20%Car energy efficiency : 25%The benefits are obvious : Just mining 1 litre of the oil out of the ground uses the same electricity to drive an EV 12 miles.
