I saw this question here: Can I have wind turbines on my base? and someone else asked about how the planet can have 60-100mph winds without very much sunlight to cause the energy differential, to which OP never gave a response. I'm now curious if there's any ways for this to occur naturally to a planet with little to no sunlight.

Background (Copied from OP)

A colony of humans has settled on a remote planet where there is little to no sunlight, but there is a plentiful amount of earth metals. E.g.- Iron, aluminium, Titanium, etc. There are high speed consistent winds that make it ideal for harvesting electricity from wind (speeds of 60 - 100mph.)

Question

How can this planet have high winds with little to no sunlight? What else could be causing high winds on a metal-rich planet like the one described?
