2 and 3)

That is actually the converted capasity (to make it easier to compare to 24 hour power plants), meaning that if it ran all day 24/7/365, the average would be 21.5 MW. It's just a conversion to make things easier to compare (so it is will provide about 1/100th the total power of your powerplants). Just FYI, the McGuire is 2 powerplants (each at about 1,100 MW), even with modern tech, the average would still only be about 1,200 per power plant, they'll just put multiple reactors on a site.

5)
$$$ = a lot of money
$ = very little money

Not really, if congress allows them to drill off the coast (or anywhere) they are going to have to spend money to build the facilities to do it (costing $$$), than they just gather the fuel, either natural gas or oil, (costing $). In the case where they just add algea tanks to exsisting refineries to recycle the CO2 emited by them, they are going to have to build the facilities (costing $$$), than they just gather the fuel, (costing $). So if congress passes and allows drilling, we are in the same boat. But if congress doesn't pass and does not allow drilling, I come out ahead. That's why I want both to happen, it provides the most fuel, thus resulting in the lowest cost for everyone.
