Energy Efficiency in Perth: How to Reduce your Electricity Bill

Perth’s scorching summers often bring eye-watering electricity bills. But what if you could slash those costs without sacrificing comfort?

This guide offers practical steps to reduce your energy consumption and keep your home cool. From uncovering hidden energy drains to maximising air-con efficiency, we’ve got you covered.

Ready to beat the heat and save money? Let’s dive in.

Hidden Energy Drains: What You Might Be Overlooking

While most people focus on obvious energy consumers like air conditioning, several lesser-known factors could be driving up your electricity bill:

1. Phantom Power and Inefficient Appliances

Also known as standby power, this silent energy drain can account for up to 10% of your home’s electricity use. Devices like tellies, computers, and mobile chargers continue to draw power even when they’re switched off. Additionally, older appliances often consume more energy than necessary.

Quick Fixes:

  • Use smart power boards that cut off power completely when devices are not in use.
  • When replacing appliances, choose models with high energy star ratings. The initial cost might be higher, but the long-term savings are substantial.
  • Only run your dishwasher and washing machine with full loads to maximise efficiency.
  • Use cold water for laundry. Up to 90% of the energy used by washing machines goes to heating water, but cold water is just as effective for most loads.

2. Inefficient Pool Pumps and Refrigeration

If you have a pool, your pump could be one of the biggest energy guzzlers in your home. Many pool owners run their pumps much longer than necessary. Similarly, your fridge, which runs 24/7, could be using more energy than it should.

Quick Fixes:

  • Upgrade to a variable speed pool pump and reduce operating hours. You can often cut pump runtime by 50% without affecting pool cleanliness.
  • For optimal efficiency, keep your fridge between 3 and 5°C and your freezer between -15 to -18 °C.
  • Clean your fridge’s condenser coils at least twice a year to reduce energy consumption.
  • Ensure your fridge and freezer doors are sealed properly to prevent cool air from escaping.
  • Keep your fridge full – it retains cold better than an empty one. If you don’t have enough food, use jugs of water.

3. Suboptimal HVAC Systems

Your heating, ventilation, and air conditioning (HVAC) system is likely the largest energy consumer in your home. Inefficiencies here can significantly impact your bill.

Quick Fixes:

  • If your current system is more than 10 years old, consider upgrading to a modern, energy-efficient air conditioner. Look for models with high energy star ratings.
  • Have your system professionally serviced at least once a year. A well-maintained system operates more efficiently.
  • Set your thermostat to 24-26°C in summer and 18-20°C in winter. Each degree closer to the outside temperature can save you up to 10% on your energy use.
  • Use ceiling or pedestal fans in conjunction with your air-con. They can make a room feel 3-4°C cooler while using much less energy.
  • To prevent false readings, ensure your thermostat is on an interior wall away from direct sunlight, air vents, and appliances.
  • Have a professional inspect and seal your ductwork. Leaks or poor connections could cause up to 30% of the air moving through your duct system to be lost.

4. Water Heating Efficiency

Water heating is often the second-largest energy expense in Perth homes. Here’s how you can reduce its impact on your bill:

Quick Fixes:

  • Set your water heater to 60°C. Any higher is unnecessary and wastes energy.
  • Insulate your water heater and pipes to reduce heat loss.
  • Consider solar hot water systems. Perth’s abundant sunshine makes these an excellent long-term investment despite the higher upfront cost.

5. Lighting Solutions

Efficient lighting can significantly reduce your energy consumption:

Quick Fixes:

  • Switch to LED bulbs. They use up to 75% less energy than incandescent bulbs and last much longer.
  • Take advantage of Perth’s abundant sunshine by opening curtains and blinds during the day.
  • Install sensors or timers to ensure lights are only on when needed, especially in less frequently used areas.

Other Home Improvements for Energy Efficiency

While these suggestions require an upfront investment, they can lead to significant long-term savings:

Quick Fixes:

  • Improve insulation in your walls, ceiling, and floor. This can reduce your heating and cooling needs by up to 40%.
  • Install double-glazed windows to significantly reduce heat gain in summer and heat loss in winter.
  • Use external shadings, such as awnings, pergolas, or strategically planted trees, to reduce the amount of heat entering your home in summer.
  • Consider solar panels. Perth’s sunny climate makes it ideal for solar energy, which can dramatically reduce or even eliminate your electricity bills in the long run.

Smart Home Technology

Embracing smart home technology can give you greater control over your energy use:

Quick Fixes:

  • Smart thermostats learn your preferences and routines, automatically adjusting your heating and cooling for optimal efficiency.
  • Smart power boards can automatically cut power to devices that aren’t in use, eliminating standby power consumption.
  • Energy monitoring systems provide real-time information about your energy use, helping you identify areas for improvement.

The Impact of Behavioural Changes

Sometimes, the most effective changes are the simplest:

  • Turn off lights and appliances when not in use.
  • Use cold water instead of hot where possible.
  • Air-dry clothes instead of using a dryer.
  • Cook with lids on pots to reduce cooking time.
  • Close doors and windows when heating or cooling.
