CSIRO says 100pc renewables possible

Technology is available to enable states and territories to move to 100 per cent renewable energy while keeping the lights on, a Senate inquiry has heard.

CSIRO economist Paul Graham told an upper house committee hearing on Friday that 100 per cent renewable energy could be delivered through the use of new battery technology, frequency control and synchronous condensers.

"There does appear to be solutions going forward to achieve whatever is desirable," Mr Graham said of renewable energy targets.
