How to Lower Your Electricity Bill

Teaching kids to find and flick off unused wall switches is a practical way to reduce standby power and save over $100 a year on your household costs.

When we think about how to reduce a power bill, we usually focus on big culprits like heat pumps or hot water cylinders. However, there is a silent drain on your bank account that has nothing to do with long showers. It is called standby power.

In 2026, specialists estimate that appliances switched off but still plugged into the wall account for roughly 5–10% of household energy use. For an average Kiwi home, this wasted energy can add up to hundreds of dollars over a few years.

Understanding Standby Power

Many modern electronics never truly turn off. They sit in standby mode while waiting for a remote signal or maintaining an internal connection. Even if a device does not have a glowing light or a digital clock, it can still be drawing a constant flow of electricity if the wall switch is left on.

Gaming consoles are notorious for drawing power to check for updates while the house is asleep. Desktop computers, monitors, and printers left on standby create a compounding draw that quietly increases your monthly spend.

Even phone chargers can draw phantom power when they are not connected to a device.

Flicking the switch at the wall is the only way to ensure these devices stop costing you money.

Involving Kids in Household Energy Savings

Turning off wall switches is a boring chore for adults but a high-stakes mission for kids.

To start, tell the children they are Power-Bill Ninjas with a mission to find every active wall switch in the house before bed.

You can provide them with a small torch to help them see behind entertainment units or under desks. Let the kids flick the switches at the wall while you help with high plugs or heavy furniture.

You can use a simple sticker chart to track their success. Ten nights of a “Dark House” earns a small treat, which is easily covered by the money you save on the power bill. It is a simple way to teach children about energy responsibility while helping the family budget.

Potential Savings for Kiwi Families

Identifying these active switches provides clear insight into your spending habits. A gaming console can leak up to $30 a year, while a desktop setup might cost you an extra $25 annually. Even small kitchen tech like coffee machines or microwaves adds up to $15 over twelve months if left switched on.

The single biggest move is often the secondary garage fridge. Unlike small electronics, an old fridge is an active load that runs a compressor constantly. Turning off an inefficient second fridge is often the most effective power-saving move a household can make.

The Bedtime Checklist

Before heading to bed, do one quick lap of the house to check for wasted energy. Look for any wall switches that are still in the on position for devices that are not being used.

Feel the plugs to see if they are warm to the touch, as warmth usually indicates a constant draw of electricity. Consider if anyone will actually use the device in the next eight hours. If a switch is hard to reach, a switched power board can make the job easier for everyone.

Think about what your family could do with an extra $100 saved this year by simply breaking these standby habits.

Key takeaway

Reducing standby power is a low-effort habit with high-reward results. While one active switch will not break the bank, ten of them running 24/7 certainly adds up. Switching off unused appliances at the wall is one of the most effective ways to reduce your monthly utility costs without changing your lifestyle.

What you can do next: Do a walk-through of your lounge tonight and count how many wall switches are left on. If you find more than five, it is time to start the 30-day Challenge to keep your hard-earned money in your pocket.
