So, Where Is The Connection?

Frequently, almost automatically, whenever oil price shoots up nuclear energy is mentioned, in positive light. This is good as in that way the public can easily see the importance and the need for nuclear energy. Looking closer, however, oil contributes only 3% to national electricity generation. Globally too oil is no longer the main source for electricity generation. So, how is oil price gets strongly connected to electricity and hence nuclear energy?
It is not so straight forward as it appears, or made out to appear. To me, the linkage is in the use of oil in the transportation sector, as primary energy source, not for electricity generation. Increasing electrification of the transportation sector, e.g. electric train, would reduce its dependence on oil and increase demand for electricity. But will that necessitate the use of nuclear energy? That is what we have to study and analyse. My view could be wrong, but that is how, for now, I look at the issue.
Depletion of fossil and other non-renewable resources, climate change, polluting behavior of fossil fuel, and the capability of renewable energy to supply electricity at the scale comparable to convetional plants appear to have direct linkage to nuclear energy, and they cannot easily be watered down, in my view.
