I usually use these energy saving tips:
Switching to energy efficient compact fluorescent lights.
Switching off appliances that are on standby and turning off anything that doesn’t need to be on.
Diverting garden and food wastes from landfill to composting.
Insulate ceilings, walls and floors.
Cool your home efficiently.
Cutting hot water usage by installing a 3 star rated showerhead, taking shorter showers.
Minimizing waste of packaging and materials - refuse, reduce, re-use, and recycle.
Choose appropriate cooking methods.
Keep the fridge clean and well ventilated.
Switching to low greenhouse impact transport options.
Using cold water to wash clothes and the sun to dry them.
Switch to Green Power.
