Earth Hour 2018

Earth Hour 2018 banner

Earth Hour is an international call for people to protect our planet by taking a stand against climate change. It began in Sydney, Australia, in 2007 as a local event and has grown into an international symbolic event focused on switching off the lights for 1 hour to act against climate change.

In 2017 an unprecedented 187 countries and territories participated and over 3000 landmarks were switched off.

Each year on the last Saturday in March, hundreds of thousands use their collective voice to inspire, motivate and lead the charge on their hopes, dreams and concerns about our planet.

This year Holy Saturday falls on the last Saturday of March. This is why Earth Hour is moving a week early rather than its traditional date.

About Earth Hour

60 minutes Earth HourThe campaign is championed by the World Wide Fund for Nature (WWF). For the past 11 years, millions of people around the world have switched off their lights for Earth Hour as a symbolic gesture to show their commitment to taking positive actions for our planet.

Earth Hour is the perfect example of the impact millions of people can have when united for a common cause. This year Earth Hour will be celebrated on Saturday, 24 March 2018, from 8:30pm to 9:30pm.

What you can do

For more information about Earth Hour, there are Earth Hour 2018 toolkits to help individuals, schools, communities, corporate and others with the following:

  • Understanding what Earth Hour is and why it’s important.
  • Explains Earth Hour 2018’s #Connect2Earth campaign objective.
  • Ideas for celebrating and contributing to Earth Hour 2018.

At the very least, please remember to switch off your lights and appliances on 24 March. Have a lantern-lit dinner party with friends or a games night by candlelight. Let’s make a collective effort to go beyond the hour and keep our electrical appliances off for as long as we can on the day and throughout the year.

16 ways to save electricity































































If you’re able to afford it, consider investing in solar water heating, and photovoltaic (PV) solar panels. When investing in a new car, consider the fuel efficiency of your vehicle, as this usually translates into the amount of carbon emitted. Also, consider hybrid or electric vehicles which have a substantially lower environmental impact, and can save you money on fluctuating petrol prices. In the case of an electric vehicle, this would cut out the need for petrol altogether. These adjustments have long-term benefits for you, your family and the planet.
