In and out of the carport a few times, plus some Teslafi usage today so a 96 watt/hr usage so far. From a negative ICE viewpoint “ya your EV consumes power when idle”.

Tho I wonder the carbon load for ICE to perform the 12V battery recovery and doing fast idle to warm the catalytic converters and bring the engine up to 90C for an optimum combustion  cycle plus provide cabin heat.  I suspect the energy cost is much higher?
