London’s Energy Use Now
•
Transport
•
•
Home
•
•
•
•
•
Keeping warm/cool (space heating, air conditioning): gas, electricity
Keeping clean (water heating, appliances): gas, electricity
Seeing at night (lighting): electricity
Having fun (ICT appliances of all sorts): electricity
Work
•
•
•
Getting about: petrol, diesel, aviation fuel, electricity
Keeping warm/cool (space heating, air conditioning): gas, electricity
Working (ICT, little industry): electricity
Infrastructure
•
•
•
•
Logistics (road, rail): petrol, diesel, electricity
Water/wastewater: electricity
Waste (landfill, recycling, energy from waste): diesel, electricity
Grids: central/local power networks, gas grid, CHP, district heating

Policy pressures
• Climate policy: �the low-carbon transition’,
80% GHG reduction by 2050, 50% by 2025
• Energy security: reliability of infrastructure,
availability of fuels
• Affordability: competitiveness of business,
affordability for households
• Climate change: implications for
infrastructure (flood defences, housing,
transport systems, water/wastewater
management, ICT networks, airports)

Implications for Energy Supply in London
• Decarbonised electricity: electricity for
transport (EVs), heating (heat pumps),
perhaps H2 for fuel cell vehicles, CHP
• Electricity network: central/local balancing
• Gas grid: CH4, H2, biogas
• Heat grid: Energy from waste/CHP/district
heating
• Transport fuels: biofuel component
• Transport infrastructure: battery/H2
service stations

Implications for Energy Demand/Practices
•
•
•
Zero-carbon buildings:
• Improved thermal performance (the Great British
Refurb)
• Building generation of heat/electricity
• Building electricity and heat management (smart
meters, variable tariffs, vehicle plug-ins, peak-load
management, responsive appliances)
• Flexible, conserving behaviours (energy will be
expensive)
Access over mobility: more cycling, walking, zeroemission vehicles
Changes more radical and dramatic than they sound:
but once made, the new practices would soon come to
seem �normal’

Policy challenges
• Price of energy:
•
•
Decarbonisation requires a high and rising carbon price
Low-carbon energy is currently more expensive than
high-carbon energy
• Energy efficiency in buildings:
•
•
•
•
Measuring performance
Builders’ skills
Building valuation
Motivating/regulating householders
• Incentivising investment:
•
•
•
Electricity Market Reform
Green Deal loans
Green Investment Bank
