I stumbled across what I thought an interesting comparison of the costs to generate electricity from the US Department of energy....includes transmission costs. http://en.wikipedia.org/wiki/Relative_cost_of_electricity_generated_by_different_sources Its shows the total cost per megawatt hour: the highest cost sources: "solar thermal" $312 what this is ?? heat or equivalent electricity? wind offshore: $243 solar PV $211 solar photovoltaic cells while gas seems to offer the lowest cost at from $66 to $125. I am surprised that "advanced nuclear" at $114 is so competitive. It sure points out the heavy subsidies (taxpayer money) required for solar. Are subsidies available for offshore power?? Seems tough for it to compete otherwise!
