What happens to wasted energy from a house?
It is wasted, and can no longer be used. Usually the energy will be in the form of heat energy, which is not concentrated enough to be of any use.
Is energy wasted in a coal - fired power plant?
Chemical energy is released when the coal burns with oxygen in the air. This energy is used to heat water, which is converted into steam. Not all of the energy is used to heat the water. Some of it is wasted by being transferred as heat to the surroundings. The energy of the steam is used to turn the turbines, but some of the steam energy is wasted.
Is all the energy in gasoline used to run the car?
No. A lot of the energy in the gasoline is wasted.
Why does a saw become warm when it is used to cut a log of wood. State the energy transformation taking place?
Mechanical energy is wasted due to friction. The wasted energy is converted into heat.
What are the way in which energy gets wasted or used in excess?
by leaving the light on.
Why does a high-efficiency machine is more desirable than low-efficiency machine?
High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.

What happens to energy that is not directley used?
It is usually wasted.

What can wasted energy in a power plant be used for?
Sea water desalination
Why is sound energy wasted when a kettle is heated?
when th kettle is heating up it making a boiling sound throught the process. This is sounded energy that is not being used hence wasted sound energy
What are Sankey diagrams used for?
They are used to show how much energy is used and how much is wasted in an object/item.
How much energy is used at each level of the energy pyramid and not passed on?
Only about 10% of energy is passed on through each energy level. The rest is used or is wasted as heat.
