I gave a virtual talk today for the Organization for Security and Co-operation in Europe and the World Energy Council on the role of  ICT in the energy transition

My talk was titled “Information and communications technology (ICT) and the energy/climate transition”, and I presented it today (November 24, 2020) at the 3rd Vienna Energy Strategy Dialogue, on the Implications of the Global Energy Transition”, Vienna, Austria.

The key points:

• Direct electricity used by ICT is modest and hasn’t grown much if at all in recent years.

• Nobody can credibly project ICT electricity use more than a few years ahead, and exaggerations of ICT electricity use abound in the literature.

• ICT is a powerful source of emissions reductions throughout the economy, which is why I call ICT our “ace in the hole” when it comes to facing the climate  challenge.
