If it is burned - which is the way such fuels are usually used - the energy efficiency is the energy efficiency of a heat engine. The theoretical maximum efficiency is the Carnot efficiency; the real efficiency will usually be considerably less than that.

What does efficiency have to do with work and work out?

Efficiency = (Useful Work done)/(Total Work done).This is usually expressed as a percentage.Example:For every 200KJ of energy released from coal in a power plant, only 60KJ is converted to electrical energy. Therefore, Efficiency = 60/200 =30%.


Does solar energy create as much energy as coal?

"Create as much energy" is poorly defined. The amount of energy produced from solar energy will depend on the surface area used for solar panels, the weather, the efficiency of the panels, and for how long it is used. Similarly, the amount of energy produced by a coal power plant would depend on its size, its efficiency (which of course may also vary), and for how long it is used. Please think about what exactly you want to compare.

How much energy is produced when you burn coal?

From <28470 kJ/kg to about 35380 kJ/kg, depending on the kind of coal and how efficiently it is burned. The figures assume 100% efficiency, which is never reached.


How many joules of thermal energy are required by a coal plant with an efficiency of 36.5 percent to generate one joule of electrical energy?

What is coal energy?

Coal energy is energy derived from the burning of coal. Coal is essentially fossilized carbon.


What type of energy does coal have?

coal have chemical energy


Where does coal get its energy?

the sun is where coal gets it energy.


Is coal an energy?

Not really. Energy is released when coal is burned. It is not coal itself, but the reaction of oxygen and coal once ignited that results in energy.


What type of energy is in coal?

chemical energy is stored in coal


Is coal a source of energy?

Yes,coal is a source of energy................


How energy is coal converted to electricity?

Electricity from coal is the electric power made from the energy stored in coal. Carbon, made from ancient plant material, gives coal most of its energy. This energy is released when coal is burned.
