When I moved oversees I moved to a place which has digital meters with SIM-cards for gas, electricity and water. I get billed what I use. I have a maximum of 30 days delay to learn whether I have a gas/water leak somewhere or whether my neighbor is 'using' my electricity to grow his 'herbs'. And overall, this saves everybody money. I can track my usage more closely, and the companies don't need to pay meter-people anymore.
