These are like AUCE resturants where inevitably those who eat the most get better value than those who eat less. Now that goes without saying, but also implys those who eat the least subsidies those who eat the most.
So in this case, those who use the least, or care most about home efficiency subsidies those who are heavy or wasteful users.
Generally a bad system for society.
