Data centre operators that buy large amounts of electricity can make huge strides in carbon reduction by embracing renewable energy across their operations and, as they invest in renewable energy procurement for their facilities, they can pass on these benefits to their customers and thus start the development of a clean energy ecosystem, says information management and storage services company Iron Mountain. Encouragingly, customers of corporate colocation data centres are increasingly seeking more sustainable energy supplies, which thanks to recent progress they will be able to access more and more, the company adds.
