While it's often overshadowed by solar panels, wind farms, and big batteries, energy efficiency remains one of the fastest and most cost-effective ways to cut emissions and reduce energy bills in our homes. Energy efficiency is the clean energy transition’s unsung hero that lets us do more with less, to use less power to achieve the same results by cutting waste and improving performance. A recent survey reveals what Australians think about home energy use, and although 85% of respondents prioritise energy efficiency, real-life uptake lags well behind. Chris Kerr, the Vice President and CEO of Clipsal by Schneider Electric, discusses the findings of their survey and how smarter design, technology, and education could help bridge the gap between good intentions and real impact.
