President Obama has articulated very
ambitious national goals
• National greenhouse gas (GHG) reduction goals:
– 17% reduction in GHG emissions by 2020
– 80% reduction in GHG emissions by 2050
• Executive Order 13514:
– 28% reduction in federal GHG emissions by 2020
– No curtailment of government missions
• Clean energy goal:
– By 2035, 80% of electricity from clean energy sources
“Some folks want wind and solar. Others want nuclear, clean coal and natural gas. To meet this goal, we will need them all..”

Summary
• The Administration is serious about moving to a clean energy portfolio
• The Government, the country’s largest consumer of energy, should lead the way to clean energy use
• A single SMR would enable ORNL to be a “net zero carbon” site while allowing for expanded missions
