Saving Your Money and the Planet in 2024: Energy Efficiency Insights

Liam Morgan • March 16, 2024

In New Zealand, a land where renewable resources like wind and hydro power breathe life into our electricity supply, we're proud that 80%-85% of our power comes from these green sources. However, the remainder, which relies on fossil fuels, still contributes to more than 6% of our nation's greenhouse gas emissions. This figure might seem small at first glance, but it's equivalent to the emissions from approximately 1.4 million petrol cars.



By cutting down our electricity consumption and opting to use power during off-peak times, we not only lessen the demand for fossil-fuelled electricity but also keep our energy bills lower.

Focus on Major Energy Consumers


With hot water and home heating devouring around two-thirds of your household electricity, targeting these areas for reductions can make a substantial difference. Below, you'll discover strategies to efficiently use hot water and heating, followed by tips for other home areas like lighting and electronic appliances.


Hot Water Usage: Every Drop Counts


  • Cold Washes: Switch to cold water for laundry to save about $50 annually, assuming four washes a week.
  • Shower Smarter: Reduce your shower time to save on water and heating costs—a brief five-minute shower could save you significantly compared to a quarter-hour soak.
  • Efficient Fixtures: Consider installing a water-efficient showerhead to significantly cut down your hot water usage, potentially saving your household up to $80 a year.
  • Repair Leaks: Fixing a leaking tap is an inexpensive way to prevent water and energy waste.
  • Dishwasher Efficiency: Only run your dishwasher when it's full, and use the eco setting if available. Pre-rinsing dishes? Stick to cold water.

Keeping Cosy for Less


  • Insulation: Starting with insulation is like giving your home a warm hug, significantly reducing the need for additional heating.
  • Seal Drafts: Eliminating drafts around doors and windows can dramatically improve your home's warmth.
  • Smart Heating Choices: When upgrading your heater, consider a heat pump for its efficiency, particularly in larger spaces.
  • Heat Wisely: Heat only the spaces you're using and set your thermostat to a comfortable, energy-efficient range.


Grants to Warm Your Heart (and Home)


Through the Warmer Kiwi Homes program, eligible homeowners can access grants for up to 90% of the cost for insulation and efficient heating solutions. This initiative makes it easier to improve your home's energy efficiency and comfort.

Beyond the Basics


After tackling hot water and heating, don't overlook other opportunities to enhance your home's energy efficiency:


  • Lighting: Swap out old, inefficient bulbs for LEDs to save energy and money.
  • Appliances: Be mindful of the energy use of appliances, especially older ones that may not be as efficient. Turning off appliances at the wall when not in use can also contribute to savings.


Looking Ahead


As technology advances, our homes will increasingly become smarter in managing energy consumption. By adopting the above measures, Kiwis can not only save money but also contribute to a healthier planet for future generations.


Taking steps towards energy efficiency is not just beneficial for your finances; it's a crucial part of our collective effort to protect our beautiful Aotearoa's environment.
