Tidal will work everywhere and will solve all the world’s problems just as I said. Ask a dumb quesiton, get a dumb answer.

The numbers I found (Which I note that you didn’t bother to look up before you wrote your reply) suggest that tidal energy can provide ~0.6% of our current global energy use, eg it doesn’t scale.
The article you just cited (http://www.forbes.com/sites/jeffmcmahon/2012/03/29/exelons-nuclear-guy-no-new-nukes/) says: "All were trumped by a portfolio that relies heavily on America’s sudden abundance of natural gas, which has flooded the market since the boom in hydraulic fracturing of shale gas. " That is to say, the reason that Exelon’s nuclear guy says that nuclear isn’t viable is because fracking (which famously has its own ecological impacts) has made natural gas cheap. Since we are talking about alternatives to hydrocarbons, cheap gas from fracking really doesn’t enter the picture.
