Yes.
In particular I'd like to point out this tidbit:
Trotting out the dollars spent per unit energy, and just
this year, is not persuasive. "[H]ow much cash the government hands out per unit of electricity produced" does not "tell the story", by itself, either. The 'story' would include the total tax dollars spent on the fossil fuel industry over the
last century helping to enable efficiency of scale, it would include pollution, it would include foreign dependence, on and on. The horse and buggy business could have made similar arguments about the nascent auto industry. When the taxpayer looks at the tax dollars actually leaving his wallet for energy purposes it is overwhelmingly all fossil fuel dollars. Fossil energy tax dollars dwarf renewable energy dollars; its in the noise. I would eliminate both if I could, but starting with fossil fuel tax deductions.
To try and duplicate that with wind would take many thousands of turbines easily costing more than $20 billion, and they only have a designed lifespan of 20 or so years.
Do the math. The Levy county plant is pricing in at ~$10,000/KW including transmission. One can argue that it should not be that high, others can have done better, etc, and I'd agree, but for the moment it is what it is. Wind (not really applicable to onshore Florida, but for instance) is $2-3000/KW, with O&M costs even less than nuclear. Other wind advantages: no major water source required, no 10 mile radius evacuation plan required, no waste piling up (because the administration killed Yucca mountain), no bet-the-company capital outlays, and no waiting until 2021 for first power when wind turbines could be producing power in two years.
How can tidal possibly be reliable if it only works twice a day?
Because it works twice a day,
every day. You're conflating reliable with variable. Both are relevant, though different. Granted nothing compares with nuclear's base load suitable capacity factor (>90%). At the moment however it seems to make a lot more sense to get that from natural gas plants - cheap to build and cheap to operate.
There's other issues too, such as low energy density which requires a great many more structures than would otherwise be needed, meaning it often takes several times the amount of materials to build the equivilent wattage output (nameplate) compared with hydro, geo, fossil fuel, and nuclear.
Perhaps, perhaps not. Nuclear containment and cooling towers require a large amount of concrete. Wind requires substantially more steel than nuclear per average Watt.
