Ercot nearly at capacity for Texas power grid
Problem is that:1) People's use of energy is relatively insensitive to price, or they don't know the price, or few people care about the price when it comes time to need it2) When you need the energy, it's too late to make the equipment/house more efficient, and when you don't need it, people don't think it's important to make it more efficient3) Mandating that people upgrade their equipment is unpopular, they vote against it, yet when they get hit with the bill for the energy later, they're unhappy with government for not having done more to control it.It's a thankless job, to be sure.  Good thing taking away people's incandescent bulbs was recognized as a threat to democracy and stopped.
