If they do make the a/c electric, I think it will be because it was what people want. I don't think it is a good idea but they aren't asking me.
Some people have the opinion that if Toyota is doing something a certain way then that must be the better way.
The main reason for hybrid vehicles (IMHO) is for better fuel efficiency. I don't mind making some sacrifice to achieve that. I could have a better ride by lowering the pressure in the tires, I would have more money if I hadn't bought two (or even one) hybrid, I would be more comfortable running max a/c. I'm willing to live with these inconveniences to get the best mileage I can.
