If a firm that is a govt service provider like EY, on behalf of a client, produces sophisticated disinformation that purports to be credible, and so misleads govt policymakers, perverts national climate strategy to expand gas production, and delays energy transition, ought lose all govt contracts

Advocacy group Climate Integrity has asked the competition regulator to investigate claims made by Australian Energy Producers, supported by EY modelling.

It alleges the claims are a form of disinformation called "data washing".

Regulator asked to investigate claim 'distorted research' behind government gas policy

Advocacy group Climate Integrity has accused the gas industry of using "distorted research", produced by the accounting firm EY, to influence the Australian government's Future Gas Strategy.

Better to farm solar for energy
than to farm crops to use for biofuels

Far better

1 hectare annual yield:

2t soy bean
➡️ 800 litres biodiesel ➡️ 8.29 MWh

70t sugar cane
➡️ 7000 litres ethanol ➡️ 57.5 MWh

600 kW solar
➡️ ➡️ 900 MWh (low estimate)

Cheapest 'fuel' is behind the meter
Farmers best to power up farm with their own solar for energy
than to farm crops to use to make biofuels

And when you do, most of the farm still left for food crops

🌞Total land required to replace coal fired energy
🌞Example assumes all solar:120,000 hectares
🌞 That’s less than 0.016 percent of Australia’s total land currently used for agriculture
🌞 Australian agriculture currently accounts for 58% of our land use
🌞And agrisolar = panels + grass/sheep etc

Actually even better: in Australia, solar farms are often just rooftops
Current 4.25m homes with solar, 27.6GW solar on rooftops
11m (38%) Aus homes
If we aim for 84GW solar (all of Aus capacity), 2/3 solar can be on roofs, so we only need 40,000ha for utility solar farms

Solar by system size - virtually everything under 14kW is on a rooftop including 4.25m homes

Yes, tho' price spikes from market caps are a diminishing risk in a high-renewables system with strong interconnection and storage. “Burning stuff” is expensive and volatile; building more renewables and batteries leaves far fewer opportunities for market gaming or rorting

Interviews in 2007 and on, I said deadline for climate solutions in place by 2020

In interviews in 2025, I was right
We needed to act in 2020☹️

Now, we can only make things less bad
We still have lots of capacity to make it worse

Wind and solar smash grid market-share records, even after heavy curtailment
Coal at new low
reneweconomy.com.au/wind-and-sol... @gilesparkinson.bsky.social @reneweconomy.com.au
Burning more fossil fuels brings higher electricity price
The more wind and solar we build, the cheaper electricity gets

If we build more renewables, add the batteries, stop burning stuff, electricity gets cheaper.

Once renewables consistently surpass ~50% of supply, wholesale market prices fall below $100/MWh"

The goal is to build much, much more than just 50% renewables

The gas industry’s push for e-methane is best seen as an effort to prolong the business case for gas infrastructure, protect legacy infrastructure and public subsidy streams, and burning stuff is not a credible pathway for rapid, affordable decarbonisation

Paris said au revoir to cars. Air pollution maps reveal a dramatic change.

Air pollution fell substantially as the city restricted car traffic and made way for parks and bike lanes.
