We need to reduce demand for energy. What if we were to mandate moving everyone to smart meters, that way we could charge X amount for first 4 kWh electricity used, then increase the charge per kWh used in tiers, that way the heaviest users would pay the most.
4kwh a day is nothing, basically a fridge and a freezer for the day. Sounds like a great life. The most frugal of users are doing 8-10kwh IF they have gas for heating.
Those who you are targeting will just install solar to cover any additional consumption as the tax makes it even more viable. Those it hurts the most with electric heating, can’t afford to mitigate against the cost.
