Read and profit.

For the unlikely event, you might read this linked article:

...However the electricity source of EVs has to be considered when determining overall vehicle efficiency, and while powering an EV via coal is not as environmentally friendly as using electricity from renewables, it doesn’t mean coal-fired charged EVs are not as efficient as ICE vehicles.

An EV motor is around 85 - 90 per cent efficient when converting coal-fired energy to power. It’s estimated that technological improvements will see emissions from combustion engines falling by about 1.9 per cent a year through to 2040, according to Bloomberg, while EV emissions are anticipated to fall between 3 per cent and 10 per cent annually.“EVs convert over 77 per cent of the electrical energy from the grid to power at the wheels. Conventional gasoline vehicles only convert about 12 per cent – 30 per cent of the energy stored in gasoline to power at the wheels,” according to the US Department of Energy[iii].The difficulty for ICE vehicles is by providing driving flexibility; they sacrifice thermodynamic efficiency. As The Driven points out, “petrol and diesel cars are very inefficient in converting the energy in their tanks into motion at the wheel ... over 60 per cent of the energy is wasted as heat.”
