By 2012 he would "require" the economy's huge energy sector to -- here things become comic -- supply half as much energy from renewable sources as already is being supplied by just one potentially renewable source. About 20 percent of America's energy comes from nuclear energy produced using fuel rods, which, when spent, can be reprocessed into fresh fuel.
Obama is (this is part of liberalism's catechism) leery of nuclear power. He also says -- and might say so even if Nevada were not a swing state -- he distrusts the safety of Nevada's Yucca Mountain for storage of radioactive waste. Evidently he prefers today's situation -- nuclear waste stored at 126 inherently insecure above-ground sites in 39 states, within 75 miles of where more than 161 million Americans live.
But back to requiring this or that quota of energy from renewable sources. What will that involve? For conservatives, seeing is believing; for liberals, believing is seeing. Obama seems to believe that if a particular outcome is desirable, one can see how to require it. But how does that work? Details to follow, sometime after noon, Jan. 20, 2009.
Where will the electricity for these million cars come from? Not nuclear power (see above). And not anywhere else, if Obama means this: "I will set a hard cap on all carbon emissions at a level that scientists say is necessary to curb global warming -- an 80 percent reduction by 2050."
No he won't. Steven Hayward of the American Enterprise Institute notes that in 2050 there will be 420 million Americans -- 40 million more households. So Obama's cap would require reducing per capita carbon emissions to levels probably below even those "in colonial days when the only fuel we burned was wood."
