UK Future Energy Scenarios Robyn Jenkins May 2012
The UK energy landscape is changing Sustainability Existing power station closures ~25% Affordability Security of supply of total capacity by 2020 Gas from UK sources ~25% of total supplies by 2020 2
The need for change 2010 2020 2050 No renewable target 15% of energy from renewables No renewable target 22% reduction in CO 2 emissions vs 1990 34% reduction in CO 2 emissions vs 1990 80% reduction in CO 2 emissions vs 1990 Electricity % of end use energy 15% 499 % of end use energy ~20% ~200 % of end use energy ~50% ~15 Gas % of end use energy 42% 184 % of end use energy ~40% 184 % of end use energy ~35% 184 Oil % of end use energy 43% 247 % of end use energy ~40% 247 % of end use energy ~15% 247 End use oil & gas excludes oil and gas used in power generation 3
The future: efficiency, decarbonisation and electrification Electricity Heat Transport Smart Meters & Appliance efficiency Insulate and reduce Efficiency and innovation Heat pump Decarbonised electricity Gas backup & embedded generation new homes & retrofit Biomethane De-carbonise heat and decarbonise transport CNG 4

Gone Green: some key themes 2020 targets 15% of energy from renewables 37% reduction in CO 2 2030 target 60% reduction in CO 2 2050 target 80% reduction in CO 2 2010 2020 2030 2040 2050 Generation mix is radically overhauled Transmission is a key enabler connecting & balancing new, diverse sources of energy Electricity demand increases, driven by electric cars & heat pumps; gas demand declines Distribution network capacity significantly increases Carbon Capture & Storage is deployed at significant scale Significant technology uncertainty, disruptors may emerge 80% reduction in CO2 is achieved Consumer energy behaviour is unrecognisable from today 6
