Taking Down Paneling Then Putting Up 1/2" Drywall need Suggestions for Insulation

Hi, I live in the midatlantic region in a end of group row house. The first floor walls are covered in paneling. I'm going to take down the paneling then install 2"x4" studs then put drywall on top of the studs. What is the most energy effective and cost effective insulation?
Thanks,
Mike

Foam sprayed in of R7 per inch is the most effective, there are foams of R5" and R 4". It is cost effective if you plan on staying there, want higher resale and understand energy costs are going up fast. 2x4 construction just does not allow the room for optimal insulation numbers, which are R40 for walls, but mid Atlantic region tells me nothing of your true climate and energy costs.

It's a small two story 1,148 sq ft brick end of group row house with double pane metal frame replacement windows. Construction is brick, lathe & plaster then paneling. I'm going to remove the paneling, insulate then install dry wall. In 1999 the local utility companies were "allowed" to deregulate beginning July 1 of this year. Electricity rates were capped at 5.9 kwh with a delivery charge about equal to the cost of electricity. I'm on the budget plan - $89.90 a month for gas and electricty . The only gas appliances in the house are water heater and gas stove. Air conditioning by high efficiency GE window air conditioners and heat is by baseboard electric heaters w/ each room having a thermostat for that room.
