Do environmental reviews improve projects or delay them and drive up costs? Two legal scholars explain how the law works and how it could influence the ongoing transition to renewable energy.
A heater with a 300-litre tank can store as much energy as a home battery at a fraction of the cost. Being able to store surplus solar energy at the right times helps grid stability and cuts emissions.
The need to limit output to the grid costs solar panel owners up to $4.5 million a year in South Australia alone. A bill of rights and responsibilities can make connecting to the grid fairer for all.
