Prescription – assume humanity should strive for:– A near-zero-emissions (indoor, urban, regional, global)

energy system with low impacts and risks to land and water

– Expansion of system to meet legitimate energy service needs of the global population

Prediction – given this sustainability prescription:– How will major energy options fare this century and

beyond?

– What might such a system cost?

– How could we achieve it?

Prescription and prediction of a

sustainable energy system

Troubled by many recent books attributing major global problems to fossil fuels – war, economic chaos, environmental harm.

“Civilization as we know it will come to an end sometime in this century unless we can find a way to live without fossil fuels.”

(Goodstein, End of the Age of Oil, Norton, 2004).

Challenges for nuclear and renewables

Nuclear power (risk perception)– Aversion to extreme event risk (focus on outcomes)

– Geopolitical risk

Renewables (uncertain costs with scale-up)– Cost declines with R&D and cumulative production

– Cost increases from scale-up related to low energy density, variable output and inconvenient location

Challenges to accelerating the efficiency trend

Ignored costs of more efficient devices– risks of long-payback and new technologies

– intangible costs of imperfect substitutes

Mega-rebound from energy productivity– direct end-use rebound

– innovation and commercialization rebound

Policy barriers– ineffectiveness of information and subsidies

– political challenge of higher prices and regulation

Fossil fuels:“the unusual suspect”

How long can they last?– reserves and resources of coal, oil and natural

gas

– substitution between fuels and with other energy

Can we use them cleanly?– history of cleaning up

– new and old challenges – urban, regional, global

Criteria for predicting social preferences

Projected cost (synthesis of numerous studies)– Depletion of higher quality resources and sites– Cost reduction through innovation– Cost reduction through greater production

(economies-of-scale and economies-of-learning)

Extreme event risk– Aversion to extreme event risk (focus on outcomes)

Geopolitical risk– Energy supply security and political independence

Path dependence– Not a decision criterion, but a long-term cost factor

Energy price increases

– Electricity final price increase of 25-50% over the next 50 years (less than 1% per year)

– Similar increases for clean burning gaseous (H2 or H2 mixed with natural gas) and liquid (biomass) fuels

Rising energy cost share of household budgets

– Increasing in typical OECD country from today’s 6% to 8% by about 2050

– Compare to 20% energy cost share of household budget in 1900 and 20% in developing countries today

Impacts for energy consumers

Careful not to bias energy regulation against clean fossil fuels– Subsidies and regulations that only

favour efficiency, renewables and nuclear

Newer approaches– Multi-sector or economy-wide cap and

trade (with safety valve)– Sector-specific regulated niche markets

Conclusion

Energy system should be seen in terms of means and ends – not good guys and bad guys.

The end is a clean, enduring and low cost energy system – with minimal extreme event and geopolitical risk.

In the pursuit of this end, fossil fuels can be part of a sustainable energy system for a very long time.
