Buy Energy-Smart Products

Buying energy-smart products may cost a little extra at the cash register, but they'll pay back the difference in energy savings in just a few years - or less.

Choosing windowsWindows and doors

Any opening in the exterior of your home can increase your heating and cooling costs by as much as 15 percent, so it's important to choose windows and doors wisely.

In fact, if all residential windows in the United States were replaced with ENERGY STAR®-qualifying models, the nation's homeowners would save $134 billion in energy costs over the next 15 years!

Heating and air conditioning

You can increase your long-term energy savings by investing in a high-efficiency 92 percent AFUE furnace — for every dollar you spend on heating energy, 92 cents is put back into your home as warmed air.

A central air conditioner's efficiency is rated as the SEER, or seasonal energy efficiency ratio. A standard unit might be a 10.0 SEER; upgrading to a 12.0 SEER can reduce your cooling costs by 15 percent.

Water heating

After heating and cooling, water heating is your home's next biggest energy user. A natural gas unit is the most efficient choice.

You can save a significant amount on your water heating costs by upgrading to a high-efficiency model and choosing the right size for your family's needs.


Looking at Energy Guide tagIf you'll be purchasing new appliances, remember that the purchase price doesn't equal the whole cost of ownership.

Choosing energy efficient models will go a long way in lowering the operating costs of your new home. Energy use can vary greatly, so be sure to check labels carefully.

Is it worth the effort? If just one in 10 homes used ENERGY STAR-qualified appliances, the environmental change would be like planting 1.7 million new acres of trees!


Instead of using energy-wasting standard incandescent bulbs, switch to compact fluorescent (CFL) or LED bulbs. CFL and LED lights use less energy to give the same amount of light as traditional bulbs. By using less energy, you will save money on your utility bill. Learn more about the Iowa Be Bright Program.
