coal twice as expensive, and natural gas is five times more expensive than nuclear in terms of dollars per kilowatt of electricity produced. And that is total cost including facilities, not just daily production costs.
the cheapest form of electricity production (even cheaper than nuclear) is hydroelectric.. however this has its downsides also. It destroys local environments on the small scale (the building of a large dam).. and it is very limited in the number of locations where it can be used. geothermal is pretty close to that of nuclear in terms of cost, and i am also a big fan of this method.
in terms of nuclear waste.. at least we can keep track of it.. after 60 years.. there it is.. all the waste we needed to power a major city in one lump, maybe the size of a house or so.. and it isnt going anywhere. the amount of waste you would create from burning fossil fuels to produce an equivalent amount of energy would be millions and millions of times more massive; less detrimental yes, but impossible to control. You have evenly distributed it all into the earth's atmosphere, oceans, and across the land. you will never get it back or be able to control it. technologies that we already have today (but are not yet cost effective or appropriate) could enable us to reduce the amount of nuclear waste by 100 times.. and possible future technology (like fusion) could result in nearly no waste.
also, we have only begun to scratch the surface of nuclear energy.. there is so much more potential there if we continue to research, vice with fossil fuels.. it isn't physically possible to make a coal or nat. gas plant run much more efficiently than they already do.
the future will require a balance of all of these. the percentages of each, i am not sure, but the only thing i know for certain is that there is no future in fossil fuels.
to completely discredit nuclear because of one's fear of what they do not understand is just ignorance.

coal has a lower energy yield by definition because it is not refined.
natural gas is many times more expensive than both coal and gasoline, and the price will continue to skyrocket (very soon, i am talking the next 5 years) to even higher than it is now.
let me say again.. there is no future in fossil fuels.. but this is a long term goal. the facts state that it is impractical at this moment.
to simply assume that you are a greener person by driving an electric car today would be incorrect, and jerk-boy's criticism of me for owning a jeep while i am very concerned about the future of the energy supply and the environment is short sighted and foolish.

yup
