Electric power transmission. Imaginary numbers are used to gauge the efficiency of appliances used at the receiving end of the power grid. You draw a little right triangle with one axis being imaginary, and the perpendicular axis being real. The real axis is what is required at the receiver's end, and the hypotenuse is the actual amount the powerco has to generate. The imaginary portion gets emitted as waste or something. LOL CIRCUITS
