Supermarket giant Woolworths has committed to source 100 per cent of its electricity from renewable sources by 2025.
Australia's largest retailer, which consumes around one per cent of the nation's electricity, announced the commitment in a statement on Thursday.
It's the latest Australian company to join the global RE100 movement which brings together businesses around the world that are committed to 100 per cent renewable power.
Woolworths Group CEO Brad Banducci said the company was proud to contribute to a greener future.
"Moving to 100 per cent renewable electricity is the right thing to do, and something a growing number of our customers, team members and shareholders expect us to lead on.
"We use around one per cent of Australia's national electricity, so we have a unique opportunity to use our scale for good and make a real impact," he said.
The company planned to invest tens of millions of dollars into renewable energy partnerships and prioritise new green energy projects to spur growth in the industry and new jobs in the sector, he said.
"We believe this will not only be a positive for our business, but also contribute to a better tomorrow by making green energy accessible to more Australians."
Woolworths will expand its network of solar panels at more than 150 locations and sign power purchase agreements with wind and solar energy providers.
Greenpeace applauded the move saying it gave Woolworths the energy edge on rival Coles, which it urged to follow suit.
Greenpeace REenergise Campaign Director Lindsay Soutar said Woolworths was the latest Australian brand giant, including ALDI, Bunnings, Officeworks and Telstra, to step up and set a strong renewable electricity target.
Woolworths has also committed to become net positive by 2050, meaning that it will be drawing down emissions from other sources.
"What Woolies does matters. There are over 1000 Woolworths supermarkets and metro stores, and 3000 stores across the group including Big W and Dan Murphy's, which employ more than 215,000 people," she said.
Woolworths going 100 per cent renewable put solar and wind power at the heart of Australian communities across the country, she said.
"Businesses like Woolies know that wind and solar just make sense. They stand to make huge savings on electricity bills, she said.
The 14 Australian members of RE100 include: Woolworths Group, Westpac, Suncorp, QBE, NAB, Mirvac, Macquarie, Interactive, Dexus, Commonwealth bank, BINGO Industries, Bank Australia, Atlassian and ANZ. More than 70 international companies with operations in Australia are also members of RE100.
