Well, "promise" it has. "Delivery" is what it needs.
How about these other highly potent sources:
geothermal
Most places the heat flux is a few 10's of kW per square km.
To get a MW you would need 100's of square km of collector.
And since the rock is not all that hot until you get quite deep,
the temps are not all that high. So the efficiency is low.
In the few places where the heat flux is high due to geological
oddities (Iceland, a few others) the total heat available isn't
that large. New Zealand is quite happy using some small
areas to heat small towns. It won't let them have free energy
to run industry.
And if you wanted to try to pull more heat out, you have the
interesting feature of cooling the rock in a volcanically
active region. I'd be wanting a pretty thorough safety
study done on that before I lived within 1000 km of it.
Maybe it's perfectly fine. Maybe it makes a cork.
nuclear
Gonna move that one to last.
tidal
Special areas. Only a few places it is convenient. I live in
Ontario, quite a long way from any possibly useful tidal
basins.
geomagnetic
Not a lot of energy available there.
Back to nuclear. The only reason we are not already using
lots more nuclear is political. There's lots of Uranium. Indeed,
were we prepared to double the price of electricity, there are
millions of tonnes of it available from proven very low quality
sources.
And we do seem to be quite happy to double the price of
electricity. Wind, for example, is getting heavily subsidized
to between two and three times the price of power from
nukes in Ontario. Solar is much higher than that. And both
of these sources release more CO2 than does nuclear,
kWhr per kWhr.
