31 Percent (Thermal to Electrical).
"According to Hans-Dieter Schilling (Energie-Fakten), the average efficiency of all coal power stations in the world currently stand at around 31%"

At 31% efficiency, if all the electricity produced was used to just generate heat (tea kettle on stove, electric heater, etc...), 2.23 times as much heat as that already goes into the cooling water at the power plant.
I generally see figures in the range of 30 to 35%. These do not include transmission losses.
Coal also is largely carbon - so bulk of heat comes from carbon burn (not hydrogen burn as say Natural Gas, which is primarily methane - CH4).

What is the energy efficiency of an average natural gas powered plant?
29 - 30%
What is the energy efficiency of a typical nuclear power plant?
The energy efficiency of a typical nuclear power plant varies, depending on its design, but a typical value might be around 33%.
What is the efficiency of a tidal power plant?
Water energy (kinetic energy) to mechanical energy to electrical energy!
What is the thermal efficiency of a plant?
The ratio of the power sent out by the plant to the energy produced from the fuel, in percent usually
What is the difference between the sun's energy and a nuclear power plant?
the sun is powered by fusion, the power plant by fission
Energy efficiency ideas?
Photosynthesis is when the plants get minerals from the sun, to make plant food, the sun is the energy which is then turned to chemical from photosynthesis.
What symbol represents the mitochondria?
Anything that makes energy. Mitochondria makes energy for the cell. You could use a nuclear powered plant.
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%.
What is a coal-fired energy plant?
A coal-fired energy plant is one that burns coal (as the source of energy) to make electricity or drive machinery.
What is the efficiency of a fossil fuel power plant?
The efficiency of a coal burning power plant is between 35% and 40%. This means that 40% of the energy is used to make electricity and the other 60% is wasted on heat and pollution through cooling towers and smoke stacks. This is the same efficiency that we had in the 1950s.
Parameters of site selection for solar power plant?
Reach energy cost reduction goals and improve utility efficiency.
Explain why the amount of useful energy always decreases when energy is changed from one form to another?
Energy conversion is not really efficient because of many factors. If we take an example of how energy are lost during conversion in our power plant. Today the efficiency rate for our coal powered plant are only 20-40%, which is an absolute waste. All those 60 or more % of energy lost is because they are converted from one form to another form many times before result is seen. Energy can be lost in forms of heat, sound mainly.
