You left out what is potentially the biggest.
Use of the ocean thermal gradient: Sea Solar Power
Also, wave power is usable only in a very few locations, where high, long period waves are continuously available. Even so, it is not going to be very cheap. Just look at the power density per linear meter of shore line and you will see that waves are not much of a resource.
The other six, repeated here for emphasis, are all practical in many places (and impractical in many others). These, together with Sea Solar Power, and NOT nuclear energy (either fusion or fission), will power the second half of this century, and beyond.
