What is energy efficiency ? And why is it so important ?

Energy efficiency means getting the most from the energy we use. You can use less energy for the same result, for example, by installing more efficient lightbulbs

New Zealanders use about 2% more energy every year. But we could save about 20% of the demand (or $2.4 billion/year) by using energy more efficiently and relying more on renewable resources.

Every one of us can make changes to help shrink the overall energy demand. As an example, a household could decrease its energy use by 20% with more efficient space heating, water heating and lighting. Plus those changes have other benefits, such as reducing energy costs and being less harmful to the environment.

How to improve your energy efficiency :

  • Switch to LED lighting or CFL bulbs instead of incandescent lighting - they last longer, which reduces the need to keep purchasing light bulbs

  • Put on an extra layer of clothing instead of turning on the heating

  • Open up your blinds and use as much natural light as possible before turning on the lights

  • Turn off your lights when you leave a room

  • Hang your wet clothes on a drying line or rack instead of using a powered dryer

  • Turn off your devices at night, including your WiFi

  • Turn off your computer before leaving work

  • Unplug workstation from ports overnight to reduce phantom power

  • Hang thick curtains and close them at nighttime to limit energy losses

  • Add an extra layer of insulation in the attic

  • Install new doors and windows - or seal the current ones

  • Install a programmable thermostat (16°C in rooms and 20°C in living room in winter)
