Move to renewables bundles false hope, bad policy and slow progress into giant mess

The Albanese government’s climate change policies are in danger of falling apart – they’re both inadequate and improbable.

One way to rescue them would be to switch solar photo-voltaic (PV) subsidies to batteries, as the Greens suggest.

Superficially, the renewable electricity target of 82 per cent by 2030 looks in good shape. At 12.30pm on September 21, the Australian national electricity market (NEM) hit a record 70 per cent renewable, because rooftop solar was at 39 per cent.

People’s roofs are consistently contributing two-fifths of Australia’s electricity during the day, which is crushing NEM demand for several hours every day and lifting the overall renewable share to two-thirds. Last Saturday in South Australia, rooftop solar ate all the electricity demand for a while, so there was none coming from utilities.
