1- Turn it off
Turn off lights, televisions, videos, stereos and computers when not in use - they can use 10 to 40% of the power when on standby. Also, unplug chargers as soon as they have finished charging.
2- Be exact
Fill the kettle with only as much water as you need.
3- Close it
Don't leave fridge doors open for longer than necessary.
4- Check your tires
Properly inflated tires can improve your car’s fuel efficiency.
5- Use no plastic
Use cloth bags when going shopping and avoid buying products which use too much plastic.
6- Fan up
Instead of using air conditioners in the summer, wear cool clothes, and use a fan.
7- Drive less
Do your weekly errands in a single trip or pay your bills online. Walk, bike, ride the bus or carpool.
8- Optimize your speed
You will consume up to 25% less fuel if you drive no more than 90 km/hr.
9- Drive hybrid
A hybrid or other fuel-efficient car emits less carbon dioxide.
10- Replace them
Replace your incandescent bulb with a compact fluorescent light bulb (CFL). CFLs cost 3 to 5 times as much but use less than a third of the power. Also, replace old fridge and other appliances with energy-efficient ones.
11- Watch what you eat
Choose food produced close to your home.
Consume less, and re-use old products.
