How is electricity energy consumed?

Electric and electronic devices consume electric energy to generate desired output (i.e., light, heat, motion, etc.). During operation, some part of the energy—depending on the electrical efficiency—is consumed in unintended output, such as waste heat. Electricity has been generated in power stations since 1882.
