- In November 2020, Guy Barnett claimed that “Tasmania is now 100 per cent self-sufficient in renewable energy” (This claim actually relates only to electricity, not total energy use.)
- In July 2021 we published an analysis which showed that this claim was at least premature. For the 2020-2021 financial year, renewable electricity generation in Tasmania was at most 94.2% renewable.
- In February 2022 we redid this analysis for the 2021 calendar year. For this period renewable electricity generation was 102% of Tasmanian demand. The increase is not the result of additional renewable electricity generation infrastructure (apart from rooftop solar). Rather it results from the variability of rainfall and hence the capacity of Hydro Tasmania to generate hydroelectricity.
- Tasmania has legislated at 200% renewable electricity target for 2040. However there is no legislated or announced mechanism for meeting this target.
