 The energy consumed at the centres, a maze of cables, pipes and servers where Google processes all of the information consumed by its users, could account for as much as 2 per cent of the world's total greenhouse gas emissions.
 Using machine learning, the search giant said it has managed to reduce the energy used to cool them by as much as 40 per cent.

 For two years an AI has been analysing a wealth of data from thousands of sensors at the centres, including temperature, weather, power, and pump speeds.
