Nuclear Energy Can Save US--America�s 100 nukes equal four million barrels of oil per day.

Billions of lives and civilization itself may be at risk from the Global Warming & End of Cheap Oil, Crisis. Rising sea levels and rising oil prices could be the end of civilization as we know it. The problem is so huge that the most powerful answer, many nuclear plants, must be deployed. Currently, America‘s 100 nukes deliver the energy of four million barrels of oil per day. Wind and solar cannot do the job, and may delay the real answer too long. Still, all kinds of clean energy, plus conservation, plus reducing deforestation, will be needed to help the poor half of the world, and for civilization to survive through this century.

Bali Climate Change Conference

Reports on the Bali Climate Change Conference next month, say the aimpoint of CO2 emissions rollback to 1990, will be the year 2050, since Kyoto's 2012 date cannot be met. This makes sense, but even more years to work won't make it easy. CO2 emissions are directly linked to Q (BTU) of fossil fuels. Reducing Q from fossil fuels is the answer to climate change, which could otherwise cause water shortages, drought and famine, as well as rising sea levels.
Energy data from eia.doe.gov, actual for 1990 and 2004, and projected for 2030, plus my own raw extrapolations to 2050, are used here. Only 1990 and 2050 are given in detail.
1990 (EIA) Total 350Q/Oil 135Q/Other Fossil 165Q/Other 50Q
2050 (Ext)Total 1050Q/Oil 360Q/Other Fossil 550Q/Other150Q
(Note: 2030 total energy projected by EIA equals 700Q)
My guess of 2050 total fossil energy is 910Q. To reduce this to the 1990 level, 300Q, would take 610Q of clean energy. If we get 360Q clean energy in place of oil, it would solve or ease two problems. Oil and its CO2 will probably be gone by 2050, so equal energy will keep the economy going as oil disappears.
This 360Q could be supplied by 4500, one-gig nukes, or 13,500,000 (or equiv.) wind turbines. Either quantity by 2050 is clearly impossible. However, a large fraction of both sources will give enormous amounts of energy to help fight climate change.
Also, 360Q will still leave the need for 250Q clean energy (2050, 550Q versus the 1990, 300Q of fossil fuel), for the rollback. All of the programs that are starting up right now must be pushed hard. We need: efficiency in car mileage, and electrical devices; zero-sum forestry worldwide; concentrated solar energy plants; biofuels from anything, other than food (corn ethanol must end soon); and coal plants, which should be required by law, to sequester large fractions of their CO2.
No single source, not even nukes, will be enough; but in time, 5000 nukes and millions of wind turbines, and counting, will eventually put Earth's climate on the road to healing.
