Prof Ross Garnaut gave a lecture on the energy trilemma, a term to describe the combination of managing energy security, cost and reducing emissions.  

It was a good lecture and covered a lot of what was in the Finkel Review, the history of climate policy, current issues facing the energy industry, and the potential role of renewables and batteries going forward.

I laughed about his analogy of the Melbourne Cup and battery storage as a fast and nimble energy supplier. That is, it's being handicapped through the system of calculating energy prices as an average of 30 minutes.  Handicapping in the Melbourne Cup is good fun and makes for a closer race, in energy it reduces effectiveness of new technologies.

I tweeted a few of the lines of the speech, see below.
