factors must be considered including the
economics, politics, and cultural context
• Once these factors are considered, then one
can talk about the technology

Energy Supply
• There are significant resources in the ground
• The world is not running out of energy any
time soon
• However, a rise in unconventional sources of
energy is expected

Security of Supply
• There is a dislocation of resources around the
globe: the oil and gas are in the ground not
where the main consumers of the product are
• Thus the dislocation leads to necessary trade,
and a reliance by the consuming countries on
the stability and security of distant oil/gas
sources

Conclusions about Energy Supply
Dislocation
• The oil is where the people ARE NOT and the
coal is where the people ARE
• As countries become increasingly concerned
about supply issues, they will turn increasingly
to coal (e.g. China and partially the U.S.)
Environmental Impacts: Local Pollution
and Climate Change
• Local pollution is not so problematic: the technology exists
and is available at cost
• He gives LA as an example, how the local pollution has
improved over the past few years
• As countries/governments get more concerned they will be
more willing to invest in the available technology to remove
the local pollution.
• Climate change is more problematic
• Evidence implies CO2 concentration is rising due to fossil
fuel use (concentration increases by ~2 PPM a year)
• Many say that 2X the pre industrial level of CO2 (550 ppm)
is a widely discussed stabilization target (beyond which it
will exert a dangerous influence on the climate system
Things to Know About CO2 In the
Atmosphere in Order to Solve Problem
Emissions
•
•
•
•
•
Concentration
The lifetime of CO2 in the atmosphere is about 1000 years
About half of what we put up there stays up there
A bend in the emissions graph will just delay the time that we cross the dangerous CO2 level threshold
Rule of thumb: every 10 percent reduction in emissions buys you about 7 years before reaching the max
We need to reduce emissions by a factor of two from current levels to remain stable at the 550 ppm level, and this in
the face of doubling the demand of energy by the middle of the century, so we need to cut the common intensity of our
energy system by a factor of four
Social Barriers to Emission Reductions
•
•
•
•
•
Climate threat is intangible and diffuse; can be obscured by
natural variability
– It’s difficult to attribute things to climate change
phenomena. It’s hard to make the climate change
discussion real for people
– contrast ozone, air pollution
Energy is at the heart of economic activity
CO2 timescales are poorly matched to the political process
– Buildup and lifetime are centennial scale
– Energy infrastructure takes decades to replace
• Power plants being planned now will be emitting in
2050
• Autos last 20 years; buildings 100 years
– Political cycle is ~6 years; news cycle ~1 day
There will be inevitable distractions
– a few years of cooling
– economic downturns
– unforeseen expenses (e.g., Iraq, tsunamis, …)
Emissions, economics, and the priority of the threat vary
greatly around the world
Emissions Facts
•
21st Century emissions from the Developing World (DW) will be more important than those from the
Industrialized World (IW)
– DW emissions growing at 2.8% vs. IW growing at 1.2%
– DW will surpass IW during 2015 - 2025
DW
E
IW
•
•
t
Sobering facts
– When DW ~ IW, each 10% reduction in IW emissions is compensated by < 4 years of DW
growth
– If China’s (or India’s) per capita emissions were those of Japan, global emissions would be
40% higher
Reducing emissions is an enormous, complex challenge; technology development will play a
central role
Emissions By Source (2000)
Note: land use means
deforestation and the
like.

Land use and
agriculture are
major
contributors:
there are large
portions of the
emissions
spectrum that
are unregulated
and need work!

Technologies and Policies
• There are 4 aspects of energy technologies that make them different:
1) Scale:
-Large infrastructure, amounts of material, and numbers of units (more cars
will be built in the next 20 years than were built in the whole 20th century).
-Requires large capital and leverage of existing infrastructure.
-This is one reason way large companies should be involved in the
innovation chain early on.
2) Ubiquity of energy:
-There are many players with sometimes divergent interests (consumers,
suppliers, governments, NGOs, etc…)
3) Longevity:
-Lifetimes of large equipment and/or interoperability imply slow changes
(e.g. BP can’t just change its fuel because it must work with older cars too)
4) Incumbency:
-New energy technologies must compete in cost.
-They may not provide any qualitatively new service to the end user

There are no “silver bullets”
•
But some have a larger calibre than others !
We have about 30-40 years to deal with these problems so we have to find
those technologies which will have the biggest impact at the lowest cost
How Do We Assess Energy
Technologies?
•
•
Current technology status and plausible technical headroom: wind mills have
been around for millennia, and there will be incremental improvements, but
compare to other improvements in biological technologies
Budgets:
– Economic (cost relative to other options)
– Energy (output how many times greater than input)
– Emissions (pollution and CO2; operations and capital)
•
•
•
Materiality (at least 1TW = 5% of 2050 BAU energy demand: technology has to
scale)
Other costs - reliability, intermittency etc.
Social and political acceptability
we also must know what problem we are trying to solve!
Problems to Solve
• There are 2 problems that technology plays into
1) Concern over future availability/cost of oil and gas
2) Concern relating to threat of climate change
• It’s really hard to beat liquid hydrocarbons
• Gasoline has a lot more energy per unit mass than
liquid H2 or compressed gas
• With small weight and small space, liquid hydrocarbons
are likely to stay around for a while
• For liquid hydrocarbons, the real issue is where you get
your carbon from

Efficiency vs. Conservation
• Efficiency and conservation are NOT the same thing
• Ex 1) when steam engines became more efficient, the amount of
coal used did not decrease, but actually increased because people
used it in more and different ways
• Ex 2) supply limited situations: right now there is not enough
electricity in china to meet the demand for air conditioning. If we
make air conditioners more efficient we will keep more Chinese
cool, but will not reduce the demand for energy because it is a
supply limited situation
• The surest way to induce conservation is to either increase the price
or to enact some sort of policy. But either is politically difficult for a
government to do and remain in power
Likely 30 Year Energy Future
• Hydrocarbons will continue to dominate transportation (high energy
density)
-conventional crude/heavy oils/CTL ensure continuity of supply at
reasonable cost
• Vehicle efficiency can be at least doubled (hybrids, plug in hybrids, HCCI,
diesel)
• In the power sector coal (security) and gas (cleanliness) will continue to
dominate heat and power
-nuclear energy (security,CO2) will be a fixed, if not growing,
fraction of the mix
-renewables will find some application but will remain a small
fraction of the total
-advanced solar a wildcard
• Demand reduction will happen where economically effective or via policy
• CO2 emissions (and concentrations) continue to rise absent dramatic
global action
Necessary Steps for the Technology
• We need technically informed, coherent, and stable government
policies
-educated decision makers and an educated public
• For short/mid term technologies, we should avoid winners/losers
-a level playing field for all applicable technologies
-emissions trading
• For long term technologies, we need support for pre-competitive
research like fission, PV, biofuels, etc…
• Business needs reasonable expectation of carbon price
• Universities/labs must recognize and act on importance of energy
research (technology and policy)
• Need business to get involved in this research in the next several
decades since business like it or not is the way to get things done
