House Fan Power Usage

I was just wondering what kind of electricity a typical house fan uses. Does it use the ac current from the main house electricity or is it converted to something else, say, DC or PWM? I would like to know this for both a ceiling fan and portable fan, if possible.

Also, based on the answer to the above question, is there a more efficient way to control a fan? For example, if the fan uses AC, would it be beneficial for it to use PWM instead?

Thanks!
