Background / Motivation for Research Develop a framework for assessment
of renewable technologies having broad societal implications using decision modeling.
Literature review of energy-related multiple perspectives and decision modeling revealed gaps.
Focus on PV technologies assessment.
19
Solar PV: Growth in Global Deployment
Global Solar PV Electricity Production by End-Use Sector 2010-2050 (2009) [1]
Worldwide Distribution of PV Electricity [2]
Multiple Deployment Types
Global Expansion
20[1] “Energy Technology Roadmaps: Charting a low-carbon energy revolution,” 2009.[2] EPIA, “Global market outlook for photovoltaics until 2014,” European Photovoltaic Industry Association, 2010.
- PV is globally deployed- PV supports multiple types of deployment- Pricing at power parity
Solar PV: Technologies
21[Ref: L. Kazmerski, “Best Research Cell Efficiencies Chart,” National Renewable Energy Laboratory (NREL), 2010. ]
-Mixed landscape of technologies- Five generations- Efficiency improving- Not easy to select best technology
Multiple Perspectives: S-T-E-E-P Social
◦ Impact on society Technical
◦ Technical performance Economic
◦ Cost of technology diffusion, market adoption, and life-cycle costs (push-pull-sustenance)
Environmental◦ Impact on the environment and ecosystem
Political◦ Political motivation, policies and regulations,
market special interest, compliance, and security
22
Value of Using Multiple Perspectives Evaluate which technology is the
“winning technology” under STEEP perspectives
Identify and prioritize areas of improvements for alternative technologies being considered
Applicable to decision makers with different worldviews – e.g. electric utility, policy maker, manufacturer, etc.
23
Literature Review: Research Gaps Wide variety of multicriteria decision
making methods used in renewable energy comparisons but not all 5 STEEP perspectives considered
STEEP assessments at conceptual level not translating to specific action*
Specific and actionable criteria needed
24
* Example: In economic perspective—as part of STEEP decision models—product cost is not decomposed into a bill of materials: PV module, Balance-of-System (BoS), etc. This is typically performed as a separate economic analysis, but not as part of decision modeling.
Research Objectives Develop a comprehensive method to
evaluate solar PV technologies under the STEEP perspectives
Enable decisions in a complex environment with competing perspectives and criteria

Social Technical Economic Environmental Political
25
Research Questions How can a robust, operationalizable STEEP
model be developed? How can this model be standardized for a
broad variety of PV/renewable energy technologies?
How can decision makers with different worldviews use this model? - Policy makers - Energy utilities - Technology suppliers - Universities/National
labs
26
Decision makers’ worldview may be defined as the overall perspective from which the decision making body sets priorities.

Game Theory Development
Strategic Decision Making Strategic decision making has two main
branches:◦ Decision modeling (consensus)◦ Game theory (dissent and conflict).
Research in decision modeling has mainly focused on the ranking of alternative choices based on a consensus or combined judgments of experts and decision makers.
However, a decision model can also be used to form the basis of rational conflict and dissent.

Only this ranking changed
Even under dissent decisions can be the same.
Relationship to Game Theory Concepts
Game – HDM model (representing players) Players – perspectives (rational) Payoffs – ranking of alternatives (ordinal
values) Incomplete Information Variable Sum Game Non-Cooperative Game Normal (not extensive) Game
53
Current Game Theory Limitations Small number of players Small number of decision elements Large number of assumptions Otherwise the calculus becomes too
complex
54
Hierarchical Decision Modeling may provide an alternate approach.
Conclusion and Future Work Applications of HDM can be for cooperation
and conflict by leveraging different aspects of the model.
Future research will focus on developing game theory for HDM and also applying this approach to applications in energy, finance, and healthcare.

Strategic decision making theory involving multiple players has two branches. One is based on decision modeling and the other on game theory. Decision modeling is the research area of the author and relies on a consensus approach to rank decision alternatives. This decision analysis methodology is useful in addressing complex scenarios involving multiple decision makers and criteria. The criteria may be qualitative or quantitative and typically, compete for priority. It may be also the case of comparing “apples to oranges.” The main focus of this lecture is hierarchical decision modeling using multiple perspectives. The ranking of alternative choices is based on a consensus or combined judgments of experts and decision makers. This lecture examines the case of a hierarchical decision model that is used to assess alternative solar photovoltaic (PV) technologies under multiple perspectives including: social, technical, economic, environmental, and political (STEEP). However, this decision model can also be used to form the basis of rational conflict and dissent which is the domain of game theory and is more oriented towards conflict and cooperation to decide the winning strategy. Dissent is evident if only one dominant perspective is considered to evaluate the alternate PV technologies. By using such a decision modeling approach outcomes for both consensus and dissent scenarios can be observed. This research could be developed further to form a basis of a type of game theory with large numbers of players and preferential criteria. This area may be important since traditional game theory has limitations here.
