It's a very useful policy that can allow both buyers to save on costs, if they're careful; and utilities to decarbonise faster and introduce more renewables. For example, I know that a lot of people are taking out their natural gas heating in the UK and replace it with electric heaters that can be charged overnight when the electricity is cheap.

I would like more demand response in the US, it's a low hanging fruit. We need better protections in extreme circumstances, but that doesn't make it less useful overall.
