Global warming religionists just do not do math well.

When President Obama goes to the Copenhagen climate change summit next week, he is expected to once again declare that the U.S. will reduce its carbon emissions 83% by 2050. Even though no legally binding agreement is expected, what Mr. Obama says in Denmark will define the U.S. position in subsequent international negotiations. He will not say how the cuts will be accomplished. For Americans, the details are worth knowing.
Annual U.S. carbon-dioxide emissions currently average about 5.5 tons of carbon per person. Achieving Mr. Obama's goal would mean reducing this to 0.63 tons per person by midcentury, taking expected population growth of just under 1% per year into account. If the rest of the world were to do likewise, global carbon dioxide emissions would be 25% lower than today.
....
Here is a recipe that would work: Add 30,000 megawatts of new wind turbines every year between now and 2050 (this is nearly four times what was added in 2008, a record year). Add another 35,000 megawatts of solar photovoltaic capacity annually (more than 100 times what was added last year—a record year for solar, too).
That's just the beginning. Now multiply the nuclear reactor fleet fivefold by midcentury. Retrofit all existing coal-fired power plants with carbon capture and storage technology. And build twice as many new plants, also with carbon capture. Natural gas could substitute for coal, but only with carbon capture too. By 2050, the electric power system would be four times bigger than today. Two-thirds of the car and truck fleet would be powered by electricity, and the rest would run on advanced biofuels.
All of this would indeed reduce carbon emissions by 83%. It would also practically eliminate America's dependence on oil imports. But could it be done?
Perhaps, though not without enormous effort. Operating a power grid reliably and economically with intermittent solar and wind resources generating 40% of the electricity cannot be done today. Carbon capture and storage has yet to be demonstrated on a large scale. Meanwhile, a still vocal group of environmentalists remains adamantly opposed to nuclear energy—even though it is the only low-carbon energy source that is both scaleable and already generating large amounts of electricity.
