The graph shows the cost of energy globally at worst doubled. So Australia’s increase is double the global average. Also renewables were supposed to decrease the exposure to such global price fluctuations, or at least act as a backstop for the marginal kWh. Apparently the backstop is still much higher. And batteries do not generate energy.
