Keep showers to four minutes

Keep showers to four minutes

The way you use hot water can have a huge impact on the amount you spend on power. The average three person Auckland household could save $915/year* by reducing shower times from 10 minutes to 4 minutes. To make this really easy, set a timer on your phone or play your favourite song while showering to help you keep track of time.

*$915/year saving based on electricity costs and water costs, shower flow rate of 12L/min, 3 people in house, each having one shower per day, heating water with electricity costing 28c/kWh and water costing $3.43/1000L.

Let in free heat from the sun

Every 1 square metre of north-facing window area that gets sun is equal to running a small panel heater for free. Open curtains fully and trim any trees or foliage that might be stopping the sun from shining into your house. Close curtains half an hour before sunset to keep in that free heat.

Switch lightbulbs to LED

Switch lightbulbs to LED

LED’s use up to 80% less energy than incandescent bulbs, while producing the same amount of light. Most LEDs should last at least 15,000 hours – that’s more than 13 years if used every day for three hours. Whilst energy efficient lights can cost a bit more upfront, the energy savings make up for that many times over and you can also expect them to last much longer.  Over their lifetime you can save $290 for every standard 100W bulb replaced by an LED.  

Also, be sure to make use of natural light where possible and turn lights off when they’re not needed.

If all NZ homes had energy efficient LED lighting it could reduce peak electricity demand by 9%. Advice on what to look for when choosing a lightbulb is available here.

Keep heating between 18-21 degrees

Keep heating between 18-21 degrees

The World Health Organisation recommends heating to a minimum of 18 degrees, to reduce chances of getting sick. If you have a heat pump, set it to 21 or 22 degrees. That’s a good balance between keeping warm but not wasting energy.  For every degree higher you set your heat pump, you use 10% more electricity.

A plug-in thermostat can be attached to an existing portable heater and is a good way to ensure children’s bedrooms stay at a healthy temperature overnight.

Wash your clothes in cold water

This is a really easy way to save money on your power bill. Whenever you put the wash on, make sure it’s set to cold, and save $80 or more every year on power. A hot water wash can use 10 times more electricity than a cold wash, and modern washing machines and detergents clean well using cold water.

Hang your washing outside instead of using the dryer

Hang your washing outside instead of using the dryer

There are plenty of benefits of using the sunshine to dry your washing – it’s free, it disinfects clothing naturally, and it’s much easier on your clothes. You’ll also be saving $50 a year by doing this. 

This also means less ironing (not that there’s much need for ironing when you’re working from home).
