Safe, Secure & Sustainable Energy Supply (S3)
Vandalism, sabotage, theft
Lack of knowledge
Environment, Economy, Society
Time: today – future
Space: North – South/East
Services to society
Exposed to multiple threats
Interdependencies; increased vulnerability
Disruptions may cascade
No single owner/operator/regulator
A conflict of objectives?
US President Gerald Ford in 1975:
• „We, the United States, are not blameless. Our growing dependence upon
foreign resources has been adding to our vulnerability for years and years, and
we did nothing to prepare ourselves for such an event as the embargo of 1973.“
• „Within the next 10 years my program envisions 200 major nuclear power
plants, 250 major new coal mines, 150 major coal –fired power plants, 30 major
new refineries, 20 major new synthetic fuel plants, the drilling of many
thousands of new wells, the insulation of 18 million homes and the
manufacturing and sale of millions of new automobiles, trucks and buses that
use much less fuel.“
Security of Supply and Sustainability
• In ecology, the concept of resilience has been
introduced in 1973 by Holling.
• Resilience is the “the magnitude of disturbance
that can be absorbed before the system changes
its structure …”
• The adaptive cycle schematically represents the
four distinct ecosystem phases:
- Growth or exploitation (r)
- Conservation (K)
- Collapse or release (Ω)
- Reorganization (α)
Resilience (National Academy of Sciences)
• Ability to prepare and plan for, absorb, recover
from, and more successfully adapt to adverse
• Risk analysis quantifies probability that the system
will reach the lowest point of the critical
• Risk management helps the system prepare and
plan for adverse events.
• Resilience management integrates the temporal
capacity of a system to
absorb and recover
from adverse events,
and then adapt .

Multi-Criteria Decision Analysis (MCDA) 1/2
•Two main phases of MCDA Structuring and Evaluation
•Many important concepts of MCDA are present in the letter:
conflicting criteria, uncertainty, pairwise comparisons, value
judgments, compensation, weights, aggregation etc.
Letter of Benjamin Franklin to his friend Joseph Priestly (1772)
Multi-Criteria Decision Analysis (MCDA) 2/2
Framework for aggregating multi-disciplinary
indicators, i.e. integration of the various
quantitative technology performance measures
Has the capability to explicitly reflect subjective
social acceptance issues.
Enables to account for a wide variety of
environmental, economic and social aspects
(the 3 pillar model of sustainability) supplemented
by the security of supply in a transparent manner.
Provides an invaluable support to informed
Helps guiding a public debate and participative
Illustrates the sensitivity of the ranking to
subjective preferences provided by the various
individual or group stakeholders.

• Weighted Sum Algorithm: transparent and simple way to calculate ranking.
• Weights w1 to wm are multiplied with respective rescaled indicators (sij) and
summed up for each alternative.
• Alternatives are then ranked and the higher the value, the better it performs.
• Among basic scenarios, performance increases with more stringent CO2-policies.
• Nuclear shock scenarios are worse than related basic scenarios, CCS shock scenarios
are about the same, and price shock scenarios perform better.
Equal Weighting Case
• Unsurprisingly, scenario performance increases with more stringent CO2-policies.
• The price shock scenarios perform well, whereas failure of CCS and nuclear accident
scenarios perform badly.
• This profile favors scenarios with no or weak CO2-policies.
• FT scenarios with shocks perform worst because they lead to a high output of the
then expensive CO2.
• This profile favors scenarios with reduced use of fossil, i.e. FT and fossil fuel price
Security of Supply Centered Case
• Scenarios with no or weak CO2-policies perform worst.
• The reason is the larger share of fossil energy use in this case.
• Import dependence decreases with progressively stronger CO2-policies.
No single scenario meets all sustainability and security of supply criteria used
in SECURE; thus, trade-offs are inevitable.
Given balance between environmental, economic, social and security of supply
criteria, the global regime climate regime scenarios (without shocks) perform
best while the baseline scenario is consequently worst.
This result is with two exceptions quite stable with respect to the variations of
- Economy-centered profiles.
- Aversion towards worst consequences of severe accidents.
Under the assumptions made in the SECURE project the global regime
scenarios are highly vulnerable to shocks in form of a very severe nuclear
accident and/or failure to implement carbon capture and storage on a large
There are clear synergies between protection of climate and security of supply.
Meeting ambitious GHG-emission reduction goals by means of successful de-
carbonization of the energy supply system through expansion of renewables,
nuclear and CCS, combined with very extensive efficiency improvements, is
also highly beneficial for security of supply.
