Energy Calculators

Thinking about buying one of those big-screen plasma TVs, but wondering what it might do to your electric bill? Curious about what it costs you to keep running that clunky old refrigerator? Thought about adding insulation, but wondering whether you'll save enough to cover the cost?

If you have questions like these simply use our handy HomeEnergySuite online calculators. Just input some basic information about your home, and let the calculators do the rest.

If you're thinking about replacing your old refrigerator with a newer model, the calculator will show you how much the current refrigerator costs to operate, compared to today's higher-efficiency refrigerators. It can also tell you what that plasma TV might add to your electric bill each month.

The calculators make it easy to see how your current level of air leakage and window insulation affects your electric bill compares with how much lower it would be with proper sealing and better windows.

Because the calculators consider specific aspects of a home's construction, local weather and utility rates, you can run multiple "what-if" scenarios to determine which upgrades or modifications would be most effective at reducing your energy costs.
