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.

A whole-home humidifier can impact your energy bill positively. In colder months, humidified air feels warmer, allowing you to lower your thermostat without sacrificing comfort. This can lead to energy savings as your heating system works more efficiently. However, it's crucial to use the humidifier judiciously to avoid excessive humidity, which might strain your cooling system in warmer months.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.
