Australia’s electricity market is unsustainable. Texas shows us why. A week ago Texas experienced a bout of severe weather as arctic air reached deep into the state, driving temperature down to levels that had not been experienced for 30 years. The full human toll is yet to be counted, but 20 deaths have so far been associated with motor accidents, from fires lit for warmth and from carbon-monoxide poisoning after residents used their cars to try to warm their homes. At the peak, 4.5 million people were without power in many cases for extended periods. The Texas Poison Centre received 450 calls about carbon monoxide poisoning.

Texas was a warning. Australia needs to rethink the design of its electricity market
