Change your light globes

Installing low energy light globes is one of the simplest and smartest things you can do to make your house more sustainable. Low energy globes use only 20 percent of the energy of your old incandescent lightbulbs.

That means you pay only 20 percent of the energy on your electricity bill.

They also last eight times longer, so they end up paying for themselves.
It’s a no brainer.

These days, you can get low energy light globes in a range of colours, shapes and sizes. To minimise your greenhouse gas emissions even more, try turning them off when you’re not in the room – even if it’s just for a few minutes.

Also, if there’s natural light available, use it. Try opening the curtains instead of turning on the light and make the most of the sunshine.


Downlights get me down

Halogen downlights are low voltage, but they still use about as much electricity as an ordinary incandescent globe. The problem is there tends to be so many of them – sometimes 12 downlights will light up a room which might otherwise have had two ordinary globes. There are a range of low energy alternatives, but be warned! Many are designed for 240 volt light fittings, instead of the 12 volt fittings which most downlights use. The exception is IRC halogen lights which will reduce energy use by up to 30 per cent. They cost about $12 each.  If low tech's more your style, you could just use lamps instead of your downlights. The other bit of bad news for people with downlights is that they allow heat to escape out through your roof. Damn it. But you can buy special covers which fit over the top of the downlight for about $15 per light.
