what type of coal used as fuel for cement production

How much coal, natural gas, or petroleum is used to

How much coal, natural gas, or petroleum is used to generate a kilowatthour of electricity? The amount of fuel used to generate electricity depends on the efficiency or heat rate of the generator (or power plant) and the heat content of the fuel. Power plant efficiencies (heat rates) vary by types of generators (prime movers), power plant emission controls, and other factors.
