WATER
1  Fix leaks. Fix leaking taps
One drop per second equals 7,000 litres of water wasted per year. 
2  Install a filter
Stop buying costly bottled water which adds to the landfill.

LIGHTING
3 Change your light bulbs
Lighting accounts for 15% of your energy bill. Replace old bulbs with ENERGY STAR rated bulbs.
4  Motion detector lights
Turn lights off outside when not in use.
5  Keep it dark
Light pollution is an increasing problem. Turn off outdoor lights to save energy and encourage night life such as bats and frogs. A single bat can eat tens of thousands of mosquitoes nightly. If you have safety concerns, use motion detector lights – which come on, only as needed.
6  Holiday lights
Use LED lights.
