The article emphasizes the importance of balancing supply-side infrastructure with demand-side resources to create a more cost-effective and sustainable energy system in Australia. It suggests investing in energy-efficient appliances and consumer energy resources to reduce the need for large-scale power stations and transmission networks. A new framework called FlexCost has been developed to quantify the costs of implementing assets like home batteries and EV chargers, providing decision-makers with a stronger evidence base for demand-side options. By considering both how electricity is generated and how it is used, the goal is to create a more affordable and efficient energy system that responds to local needs and is gradually deployed.
