I think they feed off it more than anything. I have found Morg's related stuff around lit light bulbs and filmed them there as well as electrical appliances while they are on. We are ourselves made up of energy..but they also are harvesting it imo, and feeding off of it as you can see them passing small bits of light between them or the chick like things always gobbling up the round energy balls. I have caused lights to go off and on, t.v.'s to change channels, dvr's will fast forward for NO reason. Desk top computer towers will switch on as soon as I'm a few inches away..you name it.
