IT needs to accelerate data
center decarbonisation
1.
Global IT energy use is already larger than that of many
countries, yet its flexible nature makes it a strong candidate
for rapid decarbonisation.
2. The levers available include shifting compute power around
the world, improving optimisation of the use of data centers,
improved design, and use of waste heat in heat networks.
3. Recent alliances between technology companies and power
companies are evidence of the strategic nature of power
to IT.

How to meet Data center AI/
Gen AI consumption increase?
IT is already a major energy user, and with accelerating energy
demand due to advances such as AI, 5G and IOT, IT must be a
major contributor to decarbonisation. This will be achieved
through continuing the efficiency push, increased compute
flexibility, careful locating of data centers, and reuse of waste
heat. There is a risk that data centers could destabilise grids
by rapidly increasing or decreasing demands, so greater
collaboration at the data center to grid interface is needed.
Technology advances are also an important enabler to the Energy
Transition, and we will need sophisticated energy management
systems, advanced designs for turbines, and better predictive
models, all of which will be underpinned by AI and generative AI.
Caroline Vateau is one of the French national experts on
sustainable IT, she has been working for more fifteen years
to measure and reduce the environmental impacts of digital
technology from semi-conductors, to datacenters, cloud,
applications and information systems. She also manage the
Digital Tech for Green Program aiming to identify and assess
the digital technologies that could be leverage to accelerate
the path to ecological transition.
