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
