WHEN the clock strikes 8.30pm this Saturday, Logan will once again plunge into darkness.
In a bid to save energy, many residents will switch off their lights and home electronics to participate in this years Earth Hour event.
One person who is particularly looking forward to the night is avid environmentalist Leigh-Chantelle Koch from Rochedale South.
"I think Earth Hour is a great idea to get the public involved in saving electricity," Ms Koch said.
"The whole concept is to make people more aware and encourage people to be more active in helping the planet."
The idea began in Sydney in 2007 when thousands of people turned off their lights for an hour to take a stance against climate change.
The event has since spread all around the world.
According to the Earth hour website, more than 5200 cities and towns in 135 countries switched off their lights for Earth Hour in 2011.
But while the idea of spending a Saturday night without electricity may seem hard to some, Ms Koch said there are numerous ways people could still enjoy the evening.
"Sometimes when the power is out, it can actually be quite relaxing," Ms Koch said.
"How about lighting some candles and reading that book you have been wanting to read for awhile.
"For Earth Hour, some of my friends organise a pot luck dinner and we have a nice meal by candle light and just talk.
"So my tip would be to make it more of a community thing instead of sitting at home by yourself."
The fifth annual Earth Hour will commence this Saturday between 8.30pm and 9.30pm.
