Does anyone know what the energy usage of the Instant Pot is overall compared to other methods of cooking? I've explored various off-grid methods of living and the energy requirements involving food (both storage and preparation) can be surprisingly high. I'm curious to see if the efficiency gained by using a pressure vessel results in substantial energy savings.
