The government plans to compel us in the UK to buy smart meters. The arguments for it are that:
It'll save the electricity companies money because meter readers wouldn't have to go out and read meters.
It'll save customers money, because more accurate measurement leads to energy savings.
I object to the compulsion aspect of this policy, I think the customer should be free to choose the type of meter they have. The supplier can publish two tariffs, one for a conventional meter, and another for a smart meter, and the customer can choose which one they think will be best for them.
