“Home energy efficiency is essential in today’s world, especially as power bills continue to rise,” says Megan Hurnard, GM Insights, Data and Communications at EECA.

An expert guide to using less power and saving money at home, available on Consumer’s website, provides practical, easy-to-follow tips that can help consumers make smart, sustainable decisions to lower their energy consumption and bills.

As Jessica Walker, Acting Head of Research and Advocacy at Consumer, explains, “Whether you’re trying to cut costs or simply want to understand your power bill better, these insights will help you make informed choices around your home.

“Small changes can lead to significant savings, and the guide covers everything from adjusting heating settings to selecting energy-efficient appliances.”

Power bill increases loom

This online guide comes at a critical time, when households face an expected increase in electricity bills from April 2025 of $10 to $25 a month, depending on location.

It will also help with suggestions for cheaper ways to cool homes during the warmer summer months and offers tips on charging electric vehicles to keep running costs as low as possible.
