US Autos (1990-2001) • Net Miles per Gallon: +4.6% • - engine efficiency: +23.0% • - weight/performance: -18.4% • Annual Miles Driven: +16% • Annual Fuel Consumption:+11% energy efficiency and conservation • Demand depends upon more than GDP • Multiple factors - geography, climate, demographics, urban planning, economic mix, technology choices, policy • For example, US per capita transport energy is > 3 times Japan • Efficiency through technology is about paying today vs tomorrow • Must be cost effective to be attractive • May not reduce demand through misuse or in supply-limited situations

climate change and CO2 emissions • CO2 concentration is rising due to fossil fuel use • The global temperature is increasing • other indicators of climate change • There is a plausible causal connection • but ~1% effect in a complex, noisy system • scientific case is complicated by natural variability, ill-understood forcings • Impacts of higher CO2 are uncertain • ~ 2X pre-industrial is a widely discussed stabilization target (550 ppm) • Reached by 2050 under BAU • Precautionary action is warranted • What could the world do? • Will we do it?
crucial facts about CO2 science • The earth absorbs anthropogenic CO2 at a limited rate • Emissions would have to drop to about half of their current value by the end of this century to stabilize atmospheric concentration at 550 ppm • This in the face of a doubling of energy demand in the next 50 years (1.5% per year emissions growth) • The lifetime of CO2 in the atmosphere is ~ 1000 years • The atmosphere will accumulate emissions during the 21st Century • Near-term emissions growth can be offset by greater long-term reductions • Modest emissions reductions only delay the growth of concentration (20% emissions reduction buys 15 years)
Concentration Emissions some stabilization scenarios
social barriers to meaningful emissions reductions • Climate threat is intangible and diffuse; can be obscured by natural variability • 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

DW E IW t implications of emissions heterogeneities • 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 • 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

evaluating energy technology options • Current technology status and plausible technical headroom • Budgets for the three E’s: • 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) • Other costs - reliability, intermittency etc. • Social and political acceptability we also must know what problem we are trying to solve!

biofuels today Food Crops for Energy • 2% of transportation pool • (Mostly) Use with existing infrastructure & vehicles • Growing support worldwide • Conversion of food crops into ethanol or biodiesel • US Corn ethanol economic for oil > $45 /bbl • Brazilian sugarcane economic for oil > $22/bbl Flex Fuel Offers in Brazil
key questions about biofuels • Costs • Biofuel production costs • Infrastructure & vehicle costs • Materiality • Is there sufficient land after food needs? • Are plant yields sufficiently high? • Environmental sustainability • Field-to-tank CO2 emissions relative to business as usual? • Agricultural practice – water, nitrogen, ecosystem diversity and robustness, sustainability, food impact • Energy balance • More energy out than in? • Does it matter?
corn ethanol is sub-optimal • Production does not scale to material impact • 20% of US corn production in 2006 (vs. 6% in 2000) was used to make ethanol displacing ~2.5% of petrol use • 17% of US corn production was exported in 2006 • The energy and environmental benefits are limited • To make 1 MJ of corn ethanol requires 0.9 MJ of other energy (0.4 MJ coal, 0.3 MJ gas, 0.04 MJ of nuclear/hydro, 0.05 MJ crude) • Net CO2 emission of corn ethanol ~18% less than petrol • Ethanol is not an optimal fuel molecule • Energy density, water, corrosive,… • There is tremendous scope to improve (energy, economics, emissions)
Harvest/Transport Germplasm Cultivation Processing A real fuel Transport Exploration Production Refining Blending Petroleum Value Chain: Agricultural Value Chain: Harvest Germplasm Cultivation Process Distribution Biofuels Value Chain: optimizing biofuels requires fusing the petroleum and agricultural value chains • Cellulose (bugs/ enzymes/ chems) • Microbial engineering • Plant integration / optimization • Co-products • Role of gasification • Tillage • Planting • Fertilizer • Water • Pest control • Crop rotation • Sustainability • Blends • Additives • Distribution • Engine mods • Species • Yield / Morphology / Development • Chemistry • Unnatural products • Stress tolerance • / Bio-overhead • Safety • Optimal catchment • In-field processing (e.g., pelletizing) • Transport energetics • Storage • Waste utilization
BP Energy Biosciences Institute to pursue these opportunities • Dedicated research organization to explore application of biology and biotechnology to energy issues • Sited at University of California – Berkeley and it’s partners, University of Illinois Urbana-Champagne and Lawrence Berkeley National Laboratory • Open “basic” and proprietary “applied” research • Initial focus on the entire biofuels production chain • Smaller programmes in Oil Recovery, hydrocarbon conversion, carbon sequestration • Involvement of BP, academia, biotechnology firms, government • $500M, 10-year commitment; operations commencing June `07

potential of demand side reduction Urban Energy Systems Low Energy Buildings • Buildings represent 40-50% of final energy consumption • Technology exists to reduce energy demand by at least 50% • Challenges are consumer behaviour, policy and business models • 75% of the world’s population will be urbanised by 2030 • Are there opportunities to integrate and optimise energy use on a city wide basis?
likely 30-year energy future • Hydrocarbons will continue to dominate transportation(high energy density) • Conventional crude / heavy oils / biofuels / CTL and GTL ensure continuity of supply at reasonable cost • Vehicle efficiency can be at least doubled (hybrids, plug-in hybrids, HCCI, diesel) • local pollution controllable at cost; CO2 emissions now ~20% of the total • Hydrogen in vehicles is a long way off, if it’s there at all • No production method simultaneously satisfies economy, security, emissions • Technical and economic barriers to distribution / on-board storage / fuel cells • Benefits are largely realizable by plausible evolution of existing technologies • Coal (security) and gas (cleanliness) will continue to dominate heat and power • Capture and storage (H2 power) practiced if CO2 concern is to be addressed • 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 around the technology • Technically informed, coherent, stable government policies • Educated decision-makers and public • For short/mid-term technologies • Avoid picking winners/losers (emissions trading) • Level playing field for all applicable technologies • For longer-term technologies • Support for pre-competitive research • Hydrates, fusion, advanced [fission, PV, biofuels, …] • Business needs reasonable expectation of “price of carbon” • Universities/labs must recognize and act on importance of energy research • Technology and policy
