Apple has dismissed a report from environmental organisation Greenpeace claiming the firm uses dirty energy to power its datacentres, arguing that it has some of the most energy-efficient datacentres in use.
Greenpeace had said that the firm, like Microsoft and Amazon, is too reliant on nuclear and coal energy.
But Apple took issue with the organisation's report, claiming that one of its major datacentres in the US draws far less energy than the Greenpeace reported.
"Our datacentre in North Carolina will draw about 20 megawatts at full capacity, and we are on track to supply more than 60 per cent of that power on-site from renewable sources including a solar farm and fuel cell installation which will each be the largest of their kind in the country," it said.
"We believe this industry-leading project will make Maiden the greenest datacentre ever built."
The firm also revealed plans to build a new datacentre in the US next year that it intends to power solely through renewable sources.
"It will be joined next year by our new facility in Oregon running on 100 per cent renewable energy."
The report from Greenpeace also criticised Microsoft and Amazon for their use of unclean technologies to power their datacentres.
Amazon also took issue with the findings, though, claiming the data and the assumptions are "inaccurate" and outlined its belief that cloud computing is far greener than traditional computing anyway.
"Instead of each company having their own datacenter that serves just them, AWS makes it possible for hundreds of thousands of companies to consolidate their datacenter use into a handful of datacenters in the AWS Cloud, resulting in much higher utilsation rates and eliminating the waste that occurs when datacenters don't operate near their capacity," it said.
"The cloud enables a combined smaller carbon footprint that significantly reduces overall consumption."
Microsoft had not responded to a request for comment.
