How much energy in the coal is lost when it's burned for electricity?
The very best coal plants have a effciency of about 45% so 55% of the energy of coal ends up as waste heat. Some power plants can send the waste heat to another user like a paper mill if one is nearby. Additional losses occur in transmission of electricity (about 7%) generator losses (2-3%) transformer losses (2%) and then further losses depending on what appliances you run. In all only about 1/3 of the energy from burned coal will end up at the end user so 2/3 of the energy is "lost". But since energy is not ever lost but just ends up in a form that cannot do any useful work.
What are useful and non-useful energy transfers in the production of electricity using coal?
Useful energy transfers in the production of electricity using coal occur when heat from burning coal is used to generate steam, which drives turbines to produce electricity. Non-useful energy transfers include heat lost through exhaust gases and in the cooling process of the power plant, which reduce the overall efficiency of the energy conversion process.
Where is most energy lost in coal fired power stations?
In coal-fired power stations, the most significant energy losses occur during the conversion of heat energy from burning coal into electricity. This is due to inefficiencies in the combustion process, heat transfer, and friction in the turbines and generators. Additionally, energy is lost through cooling systems and as waste heat in the environment.
Where does the wasted energy from a coal power station go?
The wasted energy from a coal power station is released as heat into the environment, contributing to global warming. This energy is not effectively converted into electricity and is therefore lost as thermal energy during the power generation process.
What is the useful energy transfer when coal is burnt?
Chemical energy is transferred to electrical energy! :) :p
What is one of the energy released that isn't useful when coal is burnt?
One of the energy releases that isn't useful when coal is burned is thermal energy in the form of heat that is lost to the surrounding environment, rather than being converted into useful work or electricity.

What is the not useful energy when coal is burnt?
When coal is burnt, the energy lost in the form of heat and pollutants such as carbon dioxide and ash is considered as not useful energy. This includes waste heat that is not converted into useful work or electricity.
What percent of your energy sources would be lost if coal runs out?
If coal were to run out, approximately 30% of the global energy supply would be lost, as coal currently accounts for around 30% of global electricity generation. This loss would necessitate a shift towards other energy sources such as renewables, natural gas, and nuclear power to fill the gap left by coal.

Why are coal fires inefficient?
Because a lot of the energy used to hear up the room is lost to the surroundings eg for every 100 J of energy stored in coal and released as heat about 25 J is used to heat u the room whilst the rest is lost to the surroundings
What is the useful energy transfer when coal is burnt?
Chemical energy is transferred to electrical energy! :) :p
When a fuel is burned what is lost as heat?
Hi, when fuel is burned, energy in the form of heat is given off. hope this helps
When electricity is lost due to resistance what is it turned into?
When electricity is lost due to resistance, it is converted into heat. This is known as Joule heating, where the electrical energy is dissipated as heat energy in the form of thermal energy.
What is one type energy that is released and not useful when coal is burnt?
One type of energy released and not useful when coal is burnt is thermal energy in the form of waste heat. This energy is often lost to the environment in the process of burning coal and is not harnessed for productive use.
