A power plant converts the heat energy in coal to electricity with 35% efficiency. Transmission losses are 10%. A factory then uses that electricity to make hydrogen with 50% efficiency, which is used in a fuel cell to make electricity with 80% efficiency. What is the total efficiency for converting coal energy into the final electrical energy product?
