Green energy sourced from solar panels now powers the UK's largest supercomputer.
The device is used by the Met Office in Exeter to predict the effects of climate change and is powered by electricity generated from the sun's energy.
A vast array of solar panels located in the West Country will be used to generate the power, which is the equivalent of enough energy needed for 67 homes.
The Met Office described its decision to move over to green energy as the conclusion of a review of business costs, with the new system described as less costly.
However, ITV News claimed the weather agency has come under severe criticism for its own carbon footprint, which was viewed as unacceptable for a body that deals with climate change.
