The cost of generating electricity
I stumbled across what I thought an interesting comparison of the costs to generate electricity from the US Department of energy....includes transmission costs.
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!

I thought coal was supposed to be the cheapest.
What about the cost of hydro?

that should be the cost of the electricity made by focusing sun to boil water.
hydro - my only experience is secondhand.
in 1960's my father-in-law's plant in Niagara Falls bought hydro for 2 mils/kwh,
or $2 per megawatt hour. seems incredible, today.
