I'm currently in Sydney for a conference called "Green Cities." I love this place (if only Sydney were closer to Europe or the U.S.), especially the forward thinking on energy efficiency in buildings. I was picked up from the airport in a Prius, and while talking about the weather (there are some flooding issues due to heavy rainfall), my cab driver mentioned that he was making about AUD900/quarter on his solar panels (as with all cab driver stories, let's discount this by 50 percent, but that's still a serious net cash flow). Apparently, the government promised a feed-in tariff of some 70 cents/kWh when they first started promoting solar. They quickly learned that every ray of sunshine would cost the government dearly, as retail and commercial investors rushed to cash in (Spain did something similar in the early days). Now the feed-in tariff is back to "normal" levels. With current prices of solar, it's cost-competitive anyway -- if only the sun would shine a little more.
This is my new Prezi, with some slides on IEQ. It features One Bligh Street in Sydney, which is almost as cool a building as 101 California in San Francisco (the streamed version of the talk is here):
