Below are two photos I snared at Darling Island this morning (just having a coffee over here).
Now, if everyone is being good, there should be no lights on tonight from 8.30pm to 9.30pm in the CBD, since it is Earth Hour.
Earth Hour is one export that we can be proud of, since, as you may recall, it began as a lights out event in Sydney back in 2007.
Today, more than 7,000 cities and one billion people globally take part in Earth Hour.
It's a great event, but realistically if companies (and people) were serious about making a difference they'd turn office lights off every night, wouldn't they?
More than that, the future must lie in investment in green technologies.
