How to Win Conservation Cup:

Turn off the Lights
  Whenever you leave a room, or even during the day when you can use natural   light, keep the lights off and save some energy!

Turn off your computer (or at least let it sleep)
  Unless you Facebook when you sleep, there’s no need for your computer while   you’re dozing. Turn it off before bed and when you leave it in your room.

Unplug things
  Don’t let your appliances be energy vampires! Unplug things like microwaves,   printers and speakers when you’re not using them. Get a power strip to make   it easy – just turn everything off and on at the flip of a switch!

Take shorter showers
  Just try it once – cut a minute or two off of your daily shower. It will give you   more free time!

Do full loads of laundry
  Think about it – not only will you save both energy and water at once, but you’ll   have to do laundry less often.
