2 Misc. Pictures Here Energy Choices

3 21 st Century Energy Supply Choices SUN - FUSION Direct solar PV, thermal Indirect solar -- wind, waves, hydro Chemical energy from photosynthesis (hydrocarbons) Biomass new (or very, very, very young coal) Fossil Fuels ancient, sequestered energy NUCLEAR - FISSION EARTH - GEOTHERMAL Primordial Radioactive decay MOON - GRAVITY Tidal

4 Life Cycle Analysis of Energy Supply Choices: Decision-making Factors Energy accessibility (related to the direct costs of energy and expected diffusion) Energy availability (related to the security/reliability dimension) Energy acceptability (environmental externalities) Relative rankings in the perspective of factors important for decision-making: F = energy source in favourable position M = energy source in medium/neutral position D = energy source in disfavoured position O = Critical USA issues not in the bounds of the study (hydro siting, nuclear waste disposal) Coal Oil Gas Biomass Nuclear Hydro Wind Solar F M M M F F D D F M F/M M F F D D D D M F F /O F /O F F After the World Energy Council, Comparison of Energy Systems Using Life Cycle Assessment, 2004 The combustion of natural gas emits almost 30 percent less carbon dioxide than oil, and just under 45 percent less carbon dioxide than coal. (these numbers do not consider refining or mining emissions)

18 Misc. Pictures Here Supply Implications: Risk and Security

19 Risk Assessment Model Criticality Import Dependence Capacity Concentration Vulnerability John Martin, 1991 (after Anderson, 1988)

20 Security of Supply and Critical Resource Dependence: USA Natural Gas Represents 20% of USA primary energy production, 22% of demand. North America supplies 99% of its natural gas demand. Many natural gas competitors with limited concentration Low supply vulnerability Petroleum Represents 11% of USA primary energy production, 40% of demand. 65% is imported. Controlled by large multinationals and national oil companies with small competitive fringe (the independents ). High supply vulnerability

21 Security of Supply and Critical Resource Dependence: NY Only 13% of NYS total primary energy requirement was met from in-state resources supplied by hydro (49%), biofuels (40%) and oil and natural gas (11%) For petroleum: New York produced only 0.1% 88% imported (47.9% from OPEC)

31 Concluding Thoughts Even realizing the state s energy efficiency and renewable energy goals, New York State will continue to need a secure liquid fuel and natural gas supply. Shale gas will be a key part of this supply for decades to come. Biomass will continue to be an important source of heating but also can serve as a liquid fuel source. Ultimately, natural gas will serve as a bridge to the expected development and maturation of renewable energy sources.
