Senator DI NATALE (Victoria—Leader of the Australian Greens) (14:21): The potential gap in supply following the closure of the Liddell plant would have been more than filled by renewable energy like solar and wind if it wasn't for the Labor and Liberal parties slashing the 2020 renewable energy target. Given that they created this mess, why won't they fix it by making sure we have more renewable energy in the system and adopting AEMO's plan?
