Energy Transitions: Drivers & Outcomes
• Overcome constraints:- availability- density- lack of diversity
• Technological change enables to:- provide novel energy services- improved efficiency- expanded & diversified supply- lessened trad. environmental impacts(indoor air pollution, “decarbonization”)
• Demand & economic growth, andnew environmental impacts (climate)

Lessons from Energy Transition Research
• Lesson 1: Energy-end use key• Lesson 2: Multiple, interacting drivers• Lesson 3: Technology, efficiency,
costs, and welfare gains interact• Lesson 4: Powerful patterns
(scaling, rates of change,…)• Lesson 5: Impact of policies mixed
Lesson 1: Energy End-use Key
• End-use: dominant form of energy conversion and dominant mobilizer of energy investments (and jobs!)
• Least efficient part of energy system (highest improvement potential)
• Largely “market” driven but with important externalities and barriers (information gaps, myopia, principal-agent problems, social & environmental externalities)
• Decentralized and “granular”decisions & technologies
• Stepchild of “silver bullet”, “top-down”(supply-side biased) policies

Lessons 2&3: Interacting Drivers and Linkages income↔costs↔market size↔innovation↔TFP growth
• Micro-level:- demand pull AND supply push- extended development cycles, vulnerable
to policy intermittency and knowledge obsolescence
• Macro-level:major interactions between economy, technology, and energy services (but poorly documented)

Lesson 4: Powerful Patterns
• Path dependencies (multiple authors)but discontinuities remain enigma
• Scaling patterns and dynamics(C. Wilson)
• Lessons from systems and diffusion theories (IIASA)
• New concept: “granularity” (GEA KM24)smaller unit scale of technology=smaller investment risk, more learning/experimeningpossibilities

Lesson 5: Influence of Policies?
• No single hammer for all nails!• Good evidence at micro- and meso scale
(Dehli CNG buses, cat cars, UK smokeless zones)• Key for policy successes: patience, predictability,
credibility, alignment, documentation of success• Successful transitions: repeat of established
patterns along the energy ladder (more energy services via higher exergy quality carriers),no large-scale “leapfrogging” examples yet
• Global scale: significant transition slowdown since 1970s (conflicting policy objectives?)

A Next, Sustainability Energy Transition?
• Unfavorable baseline (no structural change)• Innovation systems (GEA ETIS) broken:
- portfolio bias (efficiency short-rifted)- spillovers blocked (BRICs exclusion)- wrong policy framework: “demand pull” (only)
(“cost buy down” leading to cost escalation)• Lack of consistent, aligned, and holistic policies
- “boom & bust” (stimulus vs. ITC phase-out)- lack of externality pricing- social returns ignored(despite “green growth” rhetoric)
