As temperatures soar across Melbourne, energy bills can skyrocket due to increased cooling needs. With thoughtful planning, you can enjoy a comfortable home environment and avoid steep electricity costs. Here are some strategies to stay cool, conserve energy, and reduce your summer expenses.
1. Optimise Your Air Conditioner Usage
Air conditioners often account for the majority of household energy consumption during summer. Setting your air conditioner between 24-26°C is not only comfortable but also economical—each degree lower adds approximately 10% more to your energy use.
In addition, ensure your air conditioner’s thermostat is positioned away from heat sources like lamps, which can cause the system to run longer than necessary.
Using fans to circulate cooled air can help, as they create a wind-chill effect, allowing you to set the air conditioner at a slightly higher temperature without compromising comfort. Portable fans in occupied rooms are a great option and significantly more energy-efficient than running the AC alone.
2. Embrace Natural Ventilation
Maximising natural airflow in the evening and early morning, when temperatures are lower, can give your cooling systems a break. Open windows and doors to create a cross-breeze, drawing in cooler air and pushing warmer air out.
To maintain cooler air inside, close your curtains or blinds during the hottest part of the day. Blockout curtains, shades, and reflective blinds are excellent for reducing the amount of heat entering your home, minimising the need for air conditioning.
3. Upgrade to Energy-Efficient Appliances
Energy-efficient appliances are not just a long-term investment but also provide immediate savings on your energy bills. For example, ceiling fans with high energy star ratings are an affordable way to keep rooms cooler, reducing the need for air conditioning.
If you’re considering a new air conditioner or fridge, look for high energy star ratings and models that adjust power based on usage. Although the initial cost might be higher, the energy savings over the appliance’s lifetime make it worthwhile.
4. Schedule Heat-Intensive Activities Wisely
On particularly hot days, consider postponing heat-generating activities like baking, using the oven, or running a clothes dryer. These activities increase indoor temperatures and force your air conditioner to work harder. Instead, opt for meals that don’t require heating or cook outdoors on a BBQ.
Laundry can be done in the early morning or late evening, and air-drying clothes outside is a great energy-free solution on hot days. Switching to LED lighting, which produces less heat than incandescent bulbs, can also help keep your space cooler.
5. Insulate Your Home for Summer Comfort
Many people associate insulation with winter, but it’s equally effective in summer. Quality insulation keeps hot air out and cool air in, stabilising indoor temperatures and reducing reliance on air conditioning. Focus on insulating your roof and walls, as these areas are most susceptible to heat gain. Proper insulation can reduce your summer energy costs by limiting how often your cooling systems need to operate.
6. Consider Solar Power
Melbourne’s sunny summer days make solar energy a practical and sustainable option. While installing solar panels is an upfront investment, it provides long-term savings by generating clean energy for your home.
Excess power can often be fed back into the grid, providing you with credits or reducing your overall energy bill. Some solar systems allow you to store power generated during the day, which can be used in the evening, further offsetting energy costs.
7. Conduct Regular Maintenance on Cooling Systems
Proper maintenance can keep your air conditioner and other cooling systems operating efficiently. Clean or replace air filters regularly to ensure optimal airflow, as clogged filters force systems to work harder, increasing energy usage.
Annual professional inspections for your air conditioner are beneficial, as they ensure all components are working as they should. Dirty fans or ducts can reduce efficiency, so a simple cleaning can prevent unnecessary energy waste.
8. Use Smart Technology for Temperature Control
Programmable thermostats and smart home technology can help you stay cool while saving energy. Set your thermostat to adjust cooling when you’re home and automatically turn off when you’re away. Some smart systems can even learn your preferences, adjusting temperature settings based on weather patterns or time of day. Smart plugs for non-essential electronics can further cut power consumption by shutting down devices when not in use.
9. Create Shade with Outdoor Landscaping
A strategic approach to landscaping can make a significant difference in indoor temperatures. Planting trees or large shrubs on the sunny side of your home provides shade and reduces heat gain. Outdoor awnings, pergolas, and shutters are also effective in keeping direct sunlight out of windows. Another option is light-coloured, reflective roofing material, which reflects more sunlight and absorbs less heat.
10. Eliminate Phantom Loads from Electronics
Even when switched off, many electronics continue to draw power, creating “phantom loads” that can increase your energy bill. To prevent this, unplug electronics when not in use or invest in power strips, allowing you to turn off multiple devices at once. Smart plugs that cut power automatically are another excellent solution for minimising unnecessary energy use.
11. Install Energy-Efficient Window Coverings
Energy-efficient window treatments help control indoor temperatures. Blackout curtains, cellular shades, and thermal blinds provide insulation by keeping out heat during the day, reducing the workload on your air conditioner. Another effective solution is window film or tinting, which reduces heat gain without obstructing your view, allowing for natural light while blocking UV rays.
12. Encourage Energy-Saving Habits in Your Household
Educating everyone in your household about energy conservation can maximise your savings. Teach children to switch off lights and fans when leaving a room, close doors and windows to keep cooled air in, and use fans before resorting to the air conditioner. By creating a culture of energy mindfulness, you can reduce energy waste and lower your summer bills.
13. Review and Compare Energy Plans
Energy providers offer various plans that may include incentives for summer savings or reduced rates for off-peak usage. Take time to compare different plans, particularly if your current plan doesn’t cater to high summer usage. Switching to a provider that rewards efficient usage or offers discounted summer rates can help you save significantly.
Final Thoughts
Melbourne’s summer temperatures might be challenging, but high energy bills don’t have to be. These practical tips can help keep your home cool and comfortable while reducing your energy expenses.
