How much power is produced from 1 gram of uranium?

Theoretically, 24,000 kWh from 1 g of uranium-235. But perhaps you mean practical power in a power plant using 3% enriched uranium. In that case it is more like 500 kWh per g. read more

With a complete combustion or fission, approx. 8 kWh of heat can be generated from 1 kg of coal, approx. 12 kWh from 1 kg of mineral oil and around 24,000,000 kWh from 1 kg of uranium-235. Related to one kilogram, uranium-235 contains two to three million times the energy equivalent of oil or coal. read more

Really depends on how you plan to get the energy out. These are the most energetic ways to react your reactant. Quark Melting (new, but still improbable at its very best). Nuclear Fusion (improbable at best given reactant). Neutron Capture (fission) = best choice now. read more

"1 gram of uranium fuel produces the same energy as 2 million grams of oil" And a half-life of 10,000 years of toxic radiation. How wonderful. Tell it to the Japanese in Fukushima. read more
