This Saturday is Earth Hour, a global event run by the Worldwide Fund for Nature. The idea is for people to turn off their non-essential electrical appliances and lights from 8:30pm until 9:30pm local time this Saturday, March 27th.
Last year, 88 countries and 4,088 cities across the world participated. The Philippines alone saved 611 MWh of electricity during the event, which is estimated to be the equivalent of shutting down a dozen coal-fired power stations for an hour.
While the economic benefits of such an event may be difficult to calculate, the main idea is to raise awareness towards the need to take action on climate change. And it's fun to participate in something like this on a global scale.
Even North Korea is getting in on the act. I guess they'll be turning off their tower of the Juche Idea for an hour.
Well, good on them, anyway.
