Energy Efficiency Auditing questions, answered by experts

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

While installing your new furnace, you should consider hiring a pro to perform a home energy audit . This audit will give you a handy list of any projects you could undertake to improve your home's overall energy efficiency rating, including replacing or sealing windows and insulating the attic. These improvements can help save you money each month in utility costs.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.
