Efficient lighting burns less fossil fuel
When we use energy efficient lighting, we burn less fossil fuel. In 2008, 20% of New Zealand's total electricity generation came from burning fossil fuels that release carbon dioxide into the air.

Home lighting in New Zealand is mainly consumed during mornings and evenings. Reducing lighting during these times can have real benefits because the generation and transmission capacity needs can be lessened.

So by using energy efficient lighting that requires less electricity (energy) we can make a real difference. By simply replacing one incandescent bulb with one equivalent CFL, you can keep half a ton of CO2 out of the atmosphere (over the life of the bulb).

Energy efficient lighting means less mercury in the environment
CFLs contain a small amount of mercury which makes them much more efficient lights than incandescent and halogen bulbs. Mercury is toxic to human health and the environment but the amount inside an individual bulb is not large enough to pose a hazard to users.

Plus, because of their energy efficiency, energy saving bulbs have the greatest overall environmental life-cycle benefits, despite containing mercury.
