Zero-cost Electricity

Well done Queenslanders. Last week the cost price of electricity got down to zero. And on other days it's been quite low.

Why?
In winter we have low daytime energy use - and lots of solar panels making electricity for free. Polluting power generators have to drop their prices to compete. It's another great thing about renewables, and inspired this cartoon.

So thankyou fellow Queenslanders, for being energy efficient and making lots of clean energy from your roof.
