10th Annual Earth Hour: BC powers down tonight

Over 400 iconic landmarks switched off their lights during Earth Hour a year ago, including Taipei 101; the Sydney Opera House; Big Ben and the Houses of Parliament in London; the Tokyo Tower; the Empire State Building in New York; Marina Bay Sands Hotel in Singapore; and the Eiffel Tower in Paris.

While many homes and businesses in the city will simply flick the light switch and go dark for Earth Hour, others are taking different steps to promote energy efficiency on Saturday.

"While the world is experiencing the impacts of climate change, we are also watching countries uniting to create climate-friendly legislation across the globe", said Mohd Rimey, country manager of Earth Hour Brunei.

The Earth Hour travels this year from Samoa (independent country) to The Cook Islands (another independent country) across the global date line in the Pacific Ocean.

The 10th annual event, organized by the World Wildlife Fund, draws participants from 178 countries and territories with the goal of shining "a light on climate action", organizers say.

Alberta's capital has taken part in every Earth Hour since 2007, when the event made its debut in Sydney, Australia. Since then, it has grown to engage more than 7,000 cities and towns across 172 countries worldwide.

The Earth Hour is observed all over the world.

"Participation in Earth Hour symbolises a commitment to change beyond the hour", the website reads.

From the Clifton Suspension Bridge to the Eiffel Tower, the Empire State Building to the Brandenburg Gate, thousands of landmarks switched off their lights to urge action on climate change.

This year the event took place on Saturday, .
