For production of electricity, possibly yes. This won't be for 50 years at least in my opinion, and what the oil sitution will be then is difficult to forecast. There is plenty of coal available. Natural gas may run out. Nuclear fission will expand to some extent, and renewables like wind will also expand. I think there will be a mixture of fuels used as far ahead as we can imagine. Fusion would have to be much easier to do than seems likely at present, to become the main source of energy.
... there is no air pollution if it is controlled.
Today these installations are not surely controlled.
I found the website K1 Project very helpful. They had several articles underneath their Learn/Energy tab which should answer any questions about nuclear fusion.
Nuclear fusion is used in some nuclear power plants that can handle the heat and radiation without suffering a meltdown. You should check out nuclear fission in power plants first.
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
Nuclear fusion occurs at the core of the sun (and other stars) providing huge amount of energy to the rest of the solar system. It has also been achieved on Earth, though not in a controlled and sustained manner.
No, they rely on fission. Controlled fusion is the holy grail of nuclear power.
Nuclear fusion on earth has not been achieved in any way that could produce power, but experiments continue.
... there is no air pollution if it is controlled.
Today nuclear fusion is not controlled at industry scale.
In a controlled fusion reaction, a process of nuclear fusion occurs, but it is controlled, so that it does not grow uncontrollably, to become, for example, a thermonuclear bomb. Note: This has not been accomplished yet.
0% No country gets any of its energy from fusion as nobody has figured out how to build a controlled fusion reactor.
Today these installations are not surely controlled.

Nuclear fusion has been used for nuclear transformation, which is the production of new materials by fusion, and for the type of specific type of transformation called nuclear synthesis, which is the production of materials not normally found in nature. It has been used in nuclear bombs, specifically fusion bombs or hydrogen bombs. There is hope that nuclear fusion can be used to provide power for generation of electricity, though this has not yet been achieved in a practical system. There is a link below to an article on nuclear fusion.
