Editor's note (March 26, 2024): The first version of this article was based on the inference that in Mr Smith's interview with 2GB he was only referring to electricity grids. After publication Mr Smith clarified that he was referring to the full energy mix. This article has been updated to reflect that, and to add information on other off-grid energy sources of four countries whose grids are 100 per cent renewable. It has also added a statement from the CSIRO responding to Mr Smith's assertions regarding that organisation. The article also previously incorrectly stated that Mr Smith had rejected renewable-led electricity generation; this has been amended. The ABC apologises to Mr Smith for the error.
