Embracing the warmth of long summer days is wonderful, but the unwelcome spike in power bills that accompanies increased air conditioner and pool usage is less enjoyable. At Solar Harness, we understand the struggle, so we’ve compiled a set of effective tips to help you slash your energy costs and mitigate the impending rise in summer utility bills.

These simple adjustments not only promise a positive impact on your next power bill but also contribute significantly to shrinking your carbon footprint. Let’s dive into 15 practical tips that you can easily implement around your home:


  1. Set your air conditioning to 24 degrees Celsius on hotter days. This temperature is optimal for standard summer conditions and even during heat waves. Each degree cooler can hike up your energy costs by 10-15%.
  2. Switch to energy-efficient lighting by replacing incandescent bulbs with compact fluorescent ones, offering substantial energy savings and a longer lifespan of about 75%.
  3. Maximize natural light on cooler days by opening curtains and blinds. Conversely, keep blinds down on hotter days to minimize heat. And always turn off lights when leaving a room.
  4. Group electronic devices like computers, laptops, printers, and scanners into a power strip for easy shutdown when not in use.
  5. Optimize your fridge’s efficiency by keeping it reasonably full, but not overloaded. A well-utilized fridge operates more efficiently, benefiting both your power bill and those holiday leftovers.
  6. Invest in fans, which are cost-effective and can reduce reliance on high-energy appliances like air conditioners.
  7. Run your dishwasher only when it’s full, using the lowest water temperature and the shortest cycle. Regularly clean the filter for efficient operation.
  8. Bar fridges may be handy for summer barbecues, but they can be power-hungry. Switch them off when not in use to save energy.
  9. Wash your clothes in cold water to save around $30 annually on your power bill. Most detergents work well at lower temperatures.
  10. Use your dryer sparingly, opting to air-dry clothes outside whenever possible. Ensure the dryer runs full loads without overloading for optimal efficiency.
  11. Illuminate your outdoor space with solar-powered lights for a festive touch during summer barbecues.
  12. For pool owners, install energy-efficient pumps and maintain cleanliness to reduce the pump’s workload. Keep pool temperatures below 27 degrees Celsius to minimize energy consumption.
  13. Before leaving for a summer holiday, turn off all devices at the wall and draw curtains or blinds to regulate home temperature and enhance security.
  14. Establish a compost bin in your garden to reduce household greenhouse gas emissions. Composting 1 kilogram of waste saves approximately 1 kilogram of greenhouse gas.
  15. Consider the ultimate tip: install a solar power system on your roof to generate free electricity from the sun year after year. This not only lowers your bills but also contributes to reducing carbon emissions.
