The right wing war on renewables is heating up as the Abbott government announces yet another investigation into wind energy and health and a review of the Renewable Energy Target.
Australian Financial Review (23 Jan) featured an opinion article by Alan Moran from the climate change denying think tank the Institute of Public Affairs criticizing renewable energy. Moran argued that the performance of solar and wind during the recent heatwave in southeast Australia proves the technology’s unreliability. It seems neither Moran or AFR made any attempt to check the facts behind his opining.
Moran’s key claim:
“during heatwave conditions in the five days to January 18 this year, wind actually contributed 3 per cent of electricity supply across the Australian National Electricity Market. Nobody knows the contribution of rooftop solar but it could not conceivably have been more than 1 per cent.”
Moran is wrong on several counts. As pointed out by RenewEconomy’s Giles Parkinson, the highest peak demand periods during the 2014 heatwave were smaller than a similar event in 2009—a time when Australia had much less solar energy capacity. For Western Australia, a state where 130,000 households have embraced rooftop solar, the peak demand in 2012 made it to 4000MW, while it was only 3733MW last week. The difference between these peaks corresponds closely to the actual installed capacity of 340MW!
As we can see, Australia’s rapidly expanding solar energy capacity clips peak demand.
South Australia and Victoria experienced a similar impact. The Australian Solar Council reported that in South Australia at the times of peak demand on January 15 to 16, rooftop solar was generating more than 9 percent of the state’s electricity demand. Other analysis investigating data from the Australian PV Institute suggest that rooftop solar not only reduced peak demand, but shifted the timing of it, reducing the need for expensive open cycle gas generators to start up.
The Australian and Australian Financial Review prosecuted a similar argument as Moran since the heatwave. These articles cherry picked a single point on Wednesday January 15 when wind generated 7.4 percent of SA’s demand to raise doubt about the effectiveness of wind energy. But this completely ignores the rest of the picture for that week.
Wind energy delivered over 20 percent of South Australia’s demand between January 16 and 17 (Thornton reference). According to Tristen Edis of Climate Spectator, wind energy provided 20.4 percent of South Australia’s electricity supply on January 14; 24 per cent on January 16; and 36 per cent on January 17.
“[B]ased on historical data,” Edis explains, “AEMO expects that during the top 10 per cent of summer demand periods, South Australian wind generation contributes at least 8.6 percent of its installed capacity for 85 per cent of the time.” That means wind energy has a bankable baseload contribution of nearly 9 percent during the worst periods of summer electricity peaks. And most of the time wind is actually producing much more than that.
It is troubling that newspapers are willing to publish fallicies about renewable energy at a time when Australia needs to rapidly rollout the infrastructure to reduce our contribution to climate change. One wonders whether this anti-renewable energy propaganda is an attempt to protect the business model of incumbent fossil fuel generators and vertically integrated gentailers. Afterall, these entities have been caught off guard by the rise of cheap renewable energy and view the technology as a threat.
Lastly, Moran argues that:
“Because of our readily available coal and gas Australian electricity costs are intrinsically among the lowest in the world. This was formerly crucial to attracting highly competitive energy-intensive industries like smelting. Australia could once again benefit from low-cost electricity if deregulation freed energy supply from its renewable obligations.”
One has to wonder if Moran is living in the 19th Century with these kind of statements. With 21st century tech companies like Google setting a 100 percent renewable energy target, Australia’s best opportunity to attract big business to our shores is by having the competitive advantage of a low emissions energy supply.

Great piece Trent!. The coal and gas industry’s misinformation campaign on renewable energy is in full swing. This is because solar and wind cut into the peak pricing events from which they make a big chunk of their income, so renewables are a real threat really wreck their business model. Its so important for pieces like this to get out there and challenge this kind of misinformation!
Why didn’t Moran argue that fewer people reported suffering from wind turbine related health problems on these days of lower input? He missed a golden opportunity there!
Thank goodness there are people like you Trent who examine ALL the evidence.
Why do we keep listening to the anti-intellectual rantings of the far right ideologues?
After the great depression, the Bretton Woods accords were put in place to ensure it didn’t happen again. When the neo-liberal ethic was put in place across the capitalist world in the eighties, the Bretton Woods accords were dismantled and, guess what? The Global Financial Crisis rolled over us. We should have expected it. We can thank the free market brigade for that.
These people want us to keep burning fossil fuels despite the fact that renewables are cheaper and of course, cleaner.
Renewable energy is delivered free of charge every day to every property in the country.
It is available to anyone who wants to tap in.
And this is not just a vague opinion.
We have been living on renewables (off grid) now for 22 years.
Low cost, reliable energy day and night.
Once a few more of us start doing it, even the Liberal Party might notice.
