How is there wind on Mars?

Sort of. There are always gas molecules, but below a certain pressure they stop acting like a gas (with characteristics like pressure, windspeed, temperature etc) and start acting like individual molecules zipping around and only occasionally hitting something.

Okay, thanks for explaining.

I've been reading about wind power on Mars, but it's hard to imagine enough 'power' to generate electricity.

Depends on how much you need. If you just need 10 watts to run a weather station - that might work well.
