A new study has found Australia’s government-owned airports could produce enough electricity to power 136,000 homes, if they had large-scale rooftop solar systems installed.

Researchers at RMIT University compared electricity generated by residential solar panels in a regional Australian city to the potential green energy production of 21 leased federal airports.

They found if large-scale solar panels were installed at the airports, they would generate 10 times more electricity than the city’s 17,000 residential panels, while offsetting 151.6 kilotons of greenhouse gasses annually.

Researcher Dr Chayn Sun said the analysis showed the value of focusing renewable energy efforts on large, centralised rooftop solar systems.

“We can’t rely on small residential solar panels to get us to a zero-emission economy but installing large panels at locations
