Brownouts are another way of saying power outage but I think are little less severe and not as widespread, might only be one city or small area where a full blown outage could affect an entire state or region of the country although it really doesn't make any difference which it is to the people affected. Just a way for a power company to make it seem less severe is all.whats a brownout? sounds dirty...
edit: So I guess it's just a PR stunt to make the company look better than it is.
