Energy Security is…

…whatever Energy Securityresearchers say…

“…continuous availability of energy invaried forms, in sufficient quantities, andat reasonable prices”United Nations DevelopmentProgram (UNDP), 2000.World Energy Assessment - Energy and theChallenge ofSustainability

“Energy insecurity can be defined as the lossof welfare that may occur as a result of achange in the price or availability of energy”Bohi and Toman (1996)

“…energy supply security must be gearedto ensuring… the uninterrupted physicalavailability of energy products on themarket, at a price which is affordable for allconsumers (private and industrial), whilerespecting environmental concerns andlooking towards sustainable development”European Commission, 2000.

Commonalities and DifferencesBetween Typical Definitions


III) Speed of Impacts: Constant – Slow Changes – Fast Changes

IV) Size of Impacts:Impending Change - Small Change - Phase Change

V) Sustention of Impacts: Transitory – Sustained – Permanent

VI) Spread of Impacts: Local – National – Global

VII) Singularity of Impacts: Unique - Seldom – Frequent

VIII) Sureness of Impacts: Deterministic – Stochastic –Heuristic - Unknown

MEASUREMENTSFew System INDICATORS

Balancing economic,environmental, and

human/social impacts


1. Clear definition of what is to be assessed,and why(Government policy, plant operation, sector regulation, etc).

2. The metrics must assess impacts on economics andbusiness, the environment, and society.

3. Coverage – key aspects must be included.

4. Available data – quantifiable empirical data.

5. Composites if appropriate (weighting).

6. Avoid duplication and needless complexity.

Framework for Analysis

1. Three domains / stores ofvalue (capital)

2. Perspectives• resource efficiency• human/social advance• environmental compatibilityIndicators reflect these

4. Identify issues associatedwith impact on External ImpactReceivers.EIR=guardian of capital

5. For each issue select anindicator

3. Identify Internal ImpactGeneratorsIIG=business process or policythat impacts a store of value

6. Quantitative measures foreach indicator – the metrics

Continuity and resilience

We used:

Our system:• Find resources• Extract resources => dispose of waste• Condition and process resources => dispose of waste• Transport resources• Convert resources => dispose of waste• Distribute (infrastructure)• Use => dispose of waste


Internal Impact Generators:• Government / Regulatory bodies• Resource extraction companies• Resource processing companies• Energy/power device manufacturers• Users

External Impact Receivers:• Consumers• Employees• Capital Providers• Utility companies• Communities• Future communities

A set of metrics not planned for some defined purposeis merely a collection of statistics.

When a measure becomes a target, it ceasesto be a good measure.

Goodhart’s Law re-stated by Marilyn Strathern

A Metrics Health Warning!


Summary

Reconceptualising Energy Security brings realisation ofthe important processes involved.

Need to create metrics in a transparentmanner to monitor progress which will….

…act as a coherent assessment of theUK's Energy Security, and guide

formulation of coherent policy.
