Australia has been urged to use "all the tools available" to deploy renewable energy as quickly as possible as the world faces the immense environmental challenge posed by climate change.
Former Chief Scientist Alan Finkel has told the Australian Hydrogen Council in Adelaide that to dramatically reduce greenhouse gas emissions and limit the impact of global warming, human civilisation was undertaking the biggest transformation of energy systems since the taming of fire.
"So substantial that in the naming traditions of the stone age, the iron age, the bronze age, and the industrial age, it could be argued that we are entering the electric age," Dr Finkel said.
