• The supply of energy from electricity, liquid hydrocarbons, and natural gas cover almost 70% of the country’s GHG emissions. 

​​

• Renewables generated 1% of the UK’s electricity in 1990, in 2010 over 6%, but by 2019 renewables accounted for 37.1%.

 

• However, low carbon electricity represented just 5% of the UK’s total energy supply in 2019.

 

• Heating and transport have lacked the same major shifts towards decarbonisation.  

​​

• Heat might be the largest “credibility gap” to the UK's Net Zero target. 

​​

• Electricity generation’s main concern could come from removing natural gas as the main form of ‘dispatchable generation’ left in the system.

 

• A whole systems perspective is needed for a coherent, cost-effective decarbonisation pathway for energy supply. 

​​

• Infrastructure is coming under increasing strain due to ongoing integration of variable renewable generation. Focus must shift to introducing flexibility across the supply sector. 

​​

• One crucial factor going beyond 2020 is the need for urgency in decision making
