Preventing Energy Waste at Home
Spray foam insulation all know about the small ways we waste energy at home, like leaving lights on or leaving appliances running when we leave a room. But there are bigger, less obvious energy-wasting mistakes you can make that have a big impact on your monthly utility bills.
Energy efficiency, such as using LED light bulbs, is an easy way to cut your electric bill. It also helps to reduce your household’s emissions of air pollution and greenhouse gases. These actions help reduce the demand for fossil fuels, which is critical to combating climate change and maintaining our national security.
If you have an old furnace or air conditioning system, a programmable thermostat is an affordable upgrade that can save you 10-12% on heating and 15% on cooling costs annually. It’s also smart to regularly replace HVAC air filters.
Top Summer Benefits of Attic Insulation You Might Not Know
Unplugging electronic devices – such as TVs, computers and chargers for cell phones or tablets – when not in use prevents “vampire loads” that can add up to 10% of your household electricity usage. If you must leave an electronics on, consider a smart power strip that shuts off idle items after a set amount of time.
Leaking ductwork allows warm or cool air to escape your home, raising HVAC energy costs. Insulating ducts can cut your energy bill by up to 40%.
