2018 – a remarkable year in energy
Global energy demand grew by 2.3% in 2018, the fastest pace this decade, driven by a robust global
economy, unseasonal weather, and moderate energy prices

Energy-related CO2 emissions hit a record high…
Higher demand for fossil fuels drove up global CO2 emissions for a second year after a brief hiatus.
Increases in efficiency, renewables, coal-to-gas switching and nuclear avoided 640 Mt of CO2 emissions.

Digitalization can help integrate variable renewables by enabling grids to better match energy
demand to times when the sun is shining and the wind is blowing.

Digitalisation ‘modernizes’ energy efficiency
Digitalisation can help energy efficiency play a more active role in electricity grids, by improving the
ability to accurately measure energy savings and understand where and when efficiency is delivered.
