Earth Hour… What is it?

On March 29th from 8 to 9 pm is Earth Hour… the hour that everyone in the world is being asked to shut off their lights, unplug everything in their house and use no energy.

Last year 2.2 Million people (and 2,100 businesses) in Sydney, Australia turned out their lights. Even landmarks like the Opera House shut off their lights. 

The concept has come the US and the rest of the world and that is the creation of Earth Hour. At the time of the writing of this post over 43,400 people in the US have signed up to shut off their lights and use no power for that hour.

From the Earth Hour website ( ) what you can do everyday at home:

  • Switch to compact fluorescent light bulbs to save money and reduce emissions. Lighting accounts for around 5% of household greenhouse gas emissions, and compact fluros use 75% less energy than an equivalent incandescent bulb. Although the bulbs cost more up-front, you will actually save money through the energy saved and extended life of the bulb.
  • Turn appliances off while not in use. Unplug any appliances like mobile phone chargers, TVs, microwaves, MP3 players, which are not being used and are on standby. In Australia, appliances on standby consume up to 10% of your electricity bill.
  • Turn off anything that doesn’t need to be on. A good rule is to turn off anything not being used. When you leave a room or leave the house, turn off your lights or appliances like the TV or computer.
  • Switch to green power. This is one of the best ways you can make a difference. Contact your electricity provider today and switch to green power, a cleaner, more renewable form of energy that does not contribute to global warming. If all Australians switched to green power today, Australia’s total greenhouse pollution would be cut by 30% in one year. That’s the equivalent of more than 40 million cars!
  • Use less hot water. This is not only a good water saving tip, it saves electricity too. Spend one minute less in the shower.
  • I encourge you all to sign up and get your friends and family to do it as well. Sign up at

    Tomorrows post will talk about fun things you can do during that hour.
