Guest Post by Geoff Russell. Geoff recently released the popular book “Greenjacked! The derailing of environmental action on climate change“.
My previous BNC post started with a story about satnavs, those great little replacements for a dog-eared street directory. Everybody understands the value of planning a route. Everybody understands that just because a road is heading in the general direction of your destination, it may not be good choice; let alone the best choice.
It might be a dead end or take you on a long circuitous route to or past your destination. Everybody knows this but when it comes to climate change, it’s as if basic smarts take a holiday and anything that can demonstrate a CO2 savings (i.e., heads in the general direction of a solution) produces cheering and cries of victory. The article went on to show that we’ve wasted over a decade with biofuels because they demonstrably cannot decarbonise our transportation system. Not ever. It was an easy argument; a slam dunk, a lay down misere.
But what about renewable energy? Specifically wind and solar? Are these dead end technologies? It certainly isn’t a slam dunk, but lets examine what’s been happening in South Australia for the past decade.
On Sunday the 8th of February, South Australian Premier Jay Weatherill called for a Royal Commission into all things nuclear after a long political history of being anti-nuclear and after being heavily involved in the past decade of wind and solar roll outs in South Australia.
This launched a small flurry of opposition with Greens Senator Mark Parnell rejecting the call with claims about any involvement in the nuclear industry by SA leading to dirty bombs; SA Conservation Council CEO Craig Wilkins invoked a threat to our clean food image. Following an op-ed by me in the Adelaide Advertiser, Wilkins followed with a letter claiming that SA couldn’t possibly have a nuclear reactor within 10 years, and went on to say that (Advertiser Letters 18th Feb):
credible commentators are suggesting that SA could be 100 percent renewable in 10 years
Why have nuclear inquiry if success is imminent?
What on earth is going on? If SA could have 100 percent of its electricity being generated by renewables in 10 years, I’d certainly be cheering and dancing in the street. And what’s with Weatherill? Doesn’t he have any “credible commentators” on his staff? Or is he getting advice from real engineers instead of credible commentators.
Let’s look at the numbers.
First a couple of interesting graphs from AEMO’s 2014 South Australian Electricity Report.
