These losses ( I2 R) on distribution lines are as a result of large currents which comes from low power factor as i said earlier in the article and this large currents(lagging currents) result from inductive power loads which most of our home equipment are made of and therefore takes lagging currents, in other for the consumers to correct this low power factor, he/she has to make use of devices like static capacitor and connect it in parallel to the load and this will help correct the losses and also help to reduce the rate of being charge for electricity.. thanks for the question @fona
