Math FAIL

Here, a reader claims that CFL's aren't as energy friendly as promised. The claim is that CFL's only require 13 watts of electricity, but actually need 28 VA from the utility company. So you save money because your meter only draws 13 watts per bulb, but stress is put on the utility company because they have to send more than that to your house.
Until the fix these issues, I'll hold on to my incandescents and carbon arc lamps, thanks."
Unfortunately, the reader fails to do the simple math required to realize that CFLs are still superior:

Normal bulb = 60 VA
CFL = 28 VA

Energy saved = 53%

Did I miss something here?

I didn't realize utility companies were so generous and selfless. That's great.
