Currently in oz positive action to cease pointless, hazardous and enormously costly coal use/mining is coming from people, the private sector, courts and great local politicians not the current unfortunately corrupt oz sports-rort federal/NSW bureaucrats.
Decades ago solar panel installation was either pay upfront or monthly around the same amount would normally pay for electricity for a few years to buy the panels and then free electricity from there (free electricity or anyone profiting by selling electricity back to the grid could be why corrupt freemasons do not like people having solar panels on their roof) Around a decade ago some great oz politicians subsidised solar panel installation for a few years to boost the smart electricity grid.
Smart electricity grids where each house, school, public building, skyscraper has its own solar panels and batteries and sells excess electricity back to the grid reliably provide electricity. Attach a small solar panel to every traffic light etc, it’s easy and low cost to implement.
