2Energy efficiency indicators in the UK
- Chris Bryant, Department of Trade and Industry
3Outline of presentation
- Use of indicators to aid policy work
- UK development work on energy efficiency
indicators - Some key UK trends revealed by the indicators
- Key sources of information to compile indicators
4Uses of indicators (1)
- To monitor the impact of policies
- To monitor progress against targets eg Kyoto
target, PSA targets - To understand trends and make projections
- To inform evidence-based policy development
5Four goals of Energy White Paper
- To put ourselves on a path to cut UKs CO2
emissions by 60 by about 2050, with real
progress by 2020 - To maintain the reliability of energy supplies
- To promote competitive markets in the UK and
beyond, helping to raise the rate of sustainable
economic growth and to improve our productivity - To ensure that every home is adequately and
affordably heated
6Use of indicators (2)
- Government will monitor progress with EWP
- goals annually. Proposed 10 key indicators
- covering
- Environment objectives
- Reliable supplies of energy
- Competitive energy markets
- Social objectives
- First includes energy ratio and energy intensity
by sector.
7Energy Review
- What is the Governments role in ensuring that
the UKs long term goal of reducing carbon
emissions is met ? - How do we develop our market framework for
delivering reliable energy supplies ? - Are there particular considerations that should
apply to nuclear ? - Are there particular considerations that should
apply to carbon abatement and other low carbon
technologies ? - Steps to take towards ensuring that every home is
adequately and affordably heated ?

10Domestic sector energy efficiency index
- Energy use energy service demandenergy
efficiency index - Energy balance model used to determine split of
changes in heating demand between comfort and
efficiency - Efficiencies of hot water provision calculated
from information on boiler efficiencies - Lighting efficiencies calculated from mix of
incandescent and energy saving lightbulbs - Appliances efficiencies based on a stock model
combined with the testing of new models

14Sources of information for domestic energy
efficiency indicators
- Overall consumption for sector from suppliers
- Estimates of consumption by end-use based on
energy balance modelling - Building Research Establishment maintain two key
models - Market Transformation Programme Models maintains
model on appliance ownership and efficiencies - Indicators also use more general information
number of households, personal disposable income
15Energy efficiency indicators in industrial sector
- Wish to use bottom-up approach here too
- But greater diversity of ways in which energy is
used than the domestic sector - Current focus is top-down indicators, energy
intensities disaggregated as far as possible - But disaggregation limited by quality of
sub-sectoral estimates of energy consumption - Research project looking at how best to introduce
bottom-up estimates and reconcile with top-down

18Output and intensity effects on industrial energy
consumption between 1990 and 2000
19Sources of information for industrial energy
efficiency indicators
- Surveys of suppliers give information on
consumption for 12 industrial groups - Annual Business Inquiry
- EU-ETS information for energy-intensive sectors
- Exploring use of linking electricity and gas
meter data to the UKs business register - National accounts information on value added by
sector - Energy Efficiency Best Practice Programme
20Service sector indicators
- Limited breakdown of this sectors consumption
from suppliers - Annual Business Inquiry provides more detail. Gas
and electricity data may offer more - Sub-sectoral intensities can be calculated in
relation to value-added, employees, floorspace - Some potential for exploring similar approach to
the domestic sector
21Service sector energy intensity
22Transport sector
- Transport service demand can be measured as
passenger miles and tonne kilometres - Also possible to measure energy efficiency of
vehicles directly - Two approaches can produce different results
23Transport sector intensities
