Energy-efficient home upgrades could help homeowners cut their annual energy bills in half while also reducing their home’s carbon footprint. But even though consumers are showing a greater interest in sustainability, nearly a third say they think green remodeling projects are too expensive, according to a survey conducted by Thumbtack, a home services website, and Rewiring America, an electrification nonprofit. Another 31% say they don’t know where to begin when considering green upgrades.

Still, low-cost sustainable projects could result in yearly savings of $200 on electricity bills, which adds up over time, the report finds. Despite their reluctance, nearly three-fourths of consumers say they’re prioritizing sustainability in their home projects this year either because they want to lower their energy bills (55%), help the planet (41%) or feel pressure from neighbors to do so (70%), according to the survey.

The findings piggyback off another recent survey from the National Association of REALTORS® that showed members find value in promoting energy efficiency in listings. The 2023 REALTORS® and Sustainability Report revealed that about a third of agents and brokers are using green data fields in their MLS to promote sustainable home features, believing them to be a selling point. Further, 17% of REALTORS® say high-performance homes—those that have undergone green improvements to increase health, operational efficiency and durability—saw an increase from 1% to 10% in the dollar value of offers compared to a similar, nonperformance home. That could equate to thousands of dollars.

How to Make a Home More Eco-Friendly

“The number one question we hear from consumers is where to start,” says Nicole Staple, head of market partnerships at Rewiring America. “Few people can afford to make these upgrades all at once, so the best first step is to take an inventory of the age of your appliances and then arrange for an energy audit of your home. From there, you can start to make a plan to switch to more efficient electric machines before your old appliances reach the end of their useful lives.”

Rewiring America and Thumbtack provide a breakdown of sustainable upgrades by budget and the potential savings that could result. They also factored in government incentives, tax credits and rebates that can help homeowners save on installation costs with some of these retrofits.
