How is anyone going to make solar paneles without oil? The manufacture
of solar panels is extraordinarily wasteful of energy. The price of
solar panels is closely linked to the price of oil.

So which part of a solar panel comes exclusively from oil?

Its energy content* by and large.

* the energy required to make it. And mine all the things that go into
it. And get it to where its got to go. And to make all the complex
electronics that help defraud consumers.

Need not come exclusvely from oil.
Nothing in the manufacture of solar panels needs come exclusively from
oil.

Would you prefer coal or gas?

Gas is preferable as it has less carbon and can be utilsed far more
efficiently.
But it could be solar and will be in the future.
