Rationalisation of demand
From Baiocchi and Minx, 2010
• 56% reduction in energy use by 2030
• Sector by Sector:– Built environment– Transport– Land-use– Industry– Behaviour
• Domestic approx 30% total emissions2030 - reduce energy use (heating & lighting) by 80%
• Non-domestic 25% of total emissions2030 - 37% reduction in emissions
• Large emphasis on retrofitting UK Buildings are incredibly inefficient
Built environment
• High proportion of natural materials low embodied energy & sequestration
• Insulating - large-scale retro-fit programme.
• Heat pumps• Thermal Comfort• Energy Service
Companies (ESCO’s)
Built environment
• Partial modal shift - private car to public transport, walking and cycling
• Reduction in passenger km
• Change of energy source from fossil fuels
• Electrification of cars, trains & LGV’s
Electric cars get a makeover
Transport - overview
• No domestic aviation, 1/3 international on current levels
• High speed electric train network
• Indigenous bioenergy & hydrogen to power HGV’s and planes
Why don’t we have these in the UK?

All Generation over a year
Balancing Supply and demand over a year
Variability overview• Variable demand
• Variable supply
• Intra-Day
• Seasonality
• Real time matching
• Balancing services
• High Voltage DC Grid
• Linking up the offshore wind-farms
• Also linking the winter wind to the summer sun
