That blue moon you saw as probably the wolf moon. And we're still in the winter season so its very likely it would be a Wolf Moon. In fact the Wolf Moon is recognized as January's full moon. If you need any reference I'd recommend looking it up here:
http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/970314a.htmlIt'll tell you all the names of the full moons for every month. Though these are just belonging to Native American Origin from what I've come to understand.
Now whether or not this does effect anyone's energy or power I think that should pertain to the individual's own beliefs. Some people believe that you can only do certain spells under certain phases of the moon. But actually affecting someone's power I honestly don't know. I think that's just a matter of opinion.
