‘A giant blanket’: how better insulation lowers energy costs for you and the grid

According to Climateworks Centre researcher Gill Armstrong, insulation works as a thermal barrier that prevents heat from escaping in winter or entering in summer. Picture it as wrapping your house in a protective blanket. When walls, attics, and basements are properly insulated, heating and cooling systems work less hard, which cuts your energy bills. But the benefits extend beyond your home: when thousands of homes are better insulated, they collectively draw less power during peak demand periods, which reduces strain on the electrical grid and can help stabilize energy prices. Better insulation is one of the most cost-effective ways to improve home energy efficiency.
