I haven’t tried Meralco’s Appliance Calculator but our electricity bill went down. Our consumption also decreases. It must be because our helpers went home, so that’s minus two consumer and that December was a cold month (minus electric fan consumption). Another reason must be because we were not home for almost a week. As you know we spend our Christmas with my mother and my siblings. What we saved from our utility bills, I’ll just use to buy appetite suppressants that work. I really gained some weight during the Holidays. This January, I still have to see. we have been using microwave everyday. Or better yet, check the Meralco’s Appliance Calculator.
