Monitoring energy use in Wales: insights from our 2021 analysis

At a glance

Commissioned by the Welsh Government, the latest iteration of the Energy Use in Wales Third Edition report explores energy consumption trends across Wales and how this varies over time. The aim is to support the Welsh Government with the development of energy policy, helping to evidence the economic, community and environmental benefits from the development of Welsh energy projects.

Here are some key highlights:

• 22% reduction in energy consumption: From 2005 to 2021, Wales reduced its total energy use from 109.7 TWh to 85.5 TWh, though 90% of total energy use in Wales is from fossil fuels
• Energy demand by use: In 2021, heating for homes, businesses, and industry made up 45% of Wales' total energy demand, followed by transport at 25%
• Energy demand by sector: The industry (37%) and domestic (27%) sectors were the largest energy consumers in 2021, in line with previous Energy Use reports
• Impact of COVID-19: Energy demand dropped by 8% in 2020, reflecting pandemic restrictions, before starting to rebound in 2021
• Regional consumption trends: From 2005 to 2021, energy use decreased across all four regions, with Cardiff Capital Region and Swansea Bay City Region together representing 71% of total annual energy consumption.

Accurately tracking and communicating progress against energy targets is crucial to the delivery of net zero. It's not just about data; it's about shaping policies and market responses that make a real impact.
