Where we get our power from is changing as more renewables feed into the energy grid. There's been a massive uptake of rooftop solar and the government has subsidies to encourage more households to buy batteries.  But if you rent or live in an apartment and can't put panels on the roof, you've largely been locked out of the benefits. That could change in part, as the federal government spruiks a new scheme to give millions of Australians a chance to get up to three hours of free electricity each day. So will the policy work? And how can we make sure the energy transition is fair and equitable?
