I'm fairly sure 90+% of the population couldn't tell you exactly what a watt, vs a gigawatt, vs a kilowatt, vs a kilowatt hour is. For most people, these units are just opaque names with vague concepts associated with them(ie kilowatt hours measures how much power you used in your home). And journalists are just members of the population, so it shouldn't be surprising that mistakes occur. A normal person's interaction with the electrical world is extremely limited, so there is little utility in having any kind of understanding of it. I'd be much more worried if journalists were confusing, say, distance measurements with weight measurements, or something like that.
