Eni's digital transformation focuses on people and technology for a new idea of the future. Digitizing means many things, it is not just a question of production processes: it also includes real life. Living today means striving for a low energy content world. For Eni, the energy revolution also involves a reduction in CO2 emissions. Let's look at Green Data Center megacomputer's consumption: supercomputers are cooled with the "free cooling" technique, which reuses air coming from outside. Between 2014 to 2017, this saved us 18 thousand tonnes of CO2 and over 50 thousand megawatts of electricity.
