Top best answers to the question «1 pound of coal produces how much electricity»
Objective: Over 56 percent of the electricity in U.S. is generated from coal. In fact, more than 84 percent of the coal consumed each year in the U.S. is used to generate electricity. It takes about one pound of coal to generate one kilowatt hour (kwh) of electricity.

Many coals have a calorific value of about 10,000 Btus per lb. So, it’s not a bad approximation to say one pound of coal generates about one kWh of electricity.
"Coal produces heat energies of 28 million to 38 million joules per 2.2 pounds" 25–35 GJ: Energy Information Sheets. Energy Information Administration. July 1998: 3. "Each ton of coal consumed at an electric power plant produces about 2000 kilowatt hours of electricity." 7.2 GJ: I.Y. Borg & C.K. Briggs. US Energy Flow. 1988: 15.
This equaled about 0.92 pounds of CO2 emissions per kWh. Emissions from electricity generation vary by type of fuel/energy source and by type and efficiency of electric power plants. The amount of CO2 produced per kWh during any period of time will vary according to the sources of electricity supplied to the electric power grid during that time.

How much carbon dioxide is produced when different fuels are burned? Different fuels emit different amounts of carbon dioxide (CO 2) in relation to the energy they produce when burned.To analyze emissions across fuels, compare the amount of CO 2 emitted per unit of energy output or heat content.. Pounds of CO 2 emitted per million British thermal units (Btu) of energy for various fuels
May 20, 2006 "Coal produces heat energies of 28 million to 38 million joules per 2.2 pounds", 25–35 GJ Fuel, MJ/kg, Btu/lb, kJ/mol Ever wondered how much energy you could get out of a ton of coal, Lignite is primarily used as fuel for steam to generate electric power.
If the batteries are manufactured in Asia (as 60% of the world’s batteries are now), more than 60% of the electricity to do so is coal-fired. Embodied energy is also necessarily a part of building wind and solar machines, especially since large quantities of concrete, steel, and glass are required. These commodity materials have relatively low embodied energy per pound, but the number of pounds involved is enormous.
In fact, more than 84 percent of the coal consumed each year in the U.S. is used to generate electricity. It takes about one pound of coal to generate one kilowatt hour (kwh) of electricity.
How much coal, natural gas, or petroleum is used to generate a kilowatthour of electricity? Coal–1.13 pounds/kWh Petroleum liquids–0.08 gallons/kWh Natural gas–7.43 cubic feet/kWh
