The world needs a new source of energy, an unspillable source.

In Hybrid cars, does the AC run while the car is using electric motor?

MPG on my Camary Hybrid went down significantly. It was hovering around 38 MPG but now I only get 30 MPG. Please help.
Mine is the 2007 Camary Hybrid. It has 12K miles on it and I noticed this over the past three tanks. I thought it was because I turned on AC 3 weeks ago. Maybe I outa get batteries checked with the dealer.
