Now daylight saving is over, Kiwi households will be replacing their failed light bulbs. The message from the Energy Efficiency and Conservation Authority (EECA) is to go one step further: replace your old-school incandescent bulbs with energy-efficient ones.
According to EECA, replacing 6 incandescent bulbs in high-use areas could save $120 a year – that’s including the cost of the bulbs. Energy-efficient CFL and LED bulbs last much longer, too.
EECA lighting manager Bill Brander says “lighting use typically doubles in autumn and winter because people are spending more time at home and the nights are longer. Lighting makes up about 12 percent of a home’s electricity bill and the average home has about 30 light bulbs – so installing energy-efficient bulbs is a very easy way to reduce energy use.”
Kiwis seem to be getting the point. Sales of energy-efficient bulbs now make up 23 percent of all light bulb sales (in 2012 this figure was 17 percent). EECA says the growing use of these bulbs generates energy savings that are equivalent to the electricity consumption of around 6000 homes.
All CFL energy-efficient bulbs must meet performance requirements. The top-performing bulbs can be identified by their blue Energy Star logo.
