An inefficient machine is said to waste energy Does this mean that energy is actually lost?

No. By wasting energy, this means that the machine is not as efficient at converting input into work as it could be. Generally the energy is converted into friction or heat by mechanical means and is counted as a loss towards viable work as it can not be utilized, but the total amount of energy is equivalent.

How a machine transforms energy into waste energy?
A machine transforms energy into waste energy in that the motor is moving fast and the waste energy is produced.
How do machines waste energy?
ANS1: (seems a bit off-topic)Thanks to the latest technological breakthroughs in waste to energy progressions, There is a new machine than converts waste to energy. It takes ordinary garbage and turns it into renewable reusable energy. http://www.wastetoenergymachines.com/ is a broker for these machines. There is a very informative video on this website that explains the whole waste to energy process and how the machines works.ANS2:A machine converts energy. Anytime energy is converted, there is loss as heat. As an example: You use a pulley (a form of first class lever) to convert your downward pull into an upward pull. As the pulley turns about its axle, friction converts some of your pull into heat. You can call that waste or you can look at it as the cost of using the machine.
Where does energy go when it seems to disapear?
When energy "disappears" it has actually turned into heat. All reactions have heat as a waste product.
What is waste thermal energy?
Waste thermal energy refers to thermal energy caused by friction. It usually a waste product that results when energy changes form or performs work.
Explain why some of the thermal energy is released by a campfire is actually a waste thermal energy?
Any time one form of energy is converted into another form . Some of the original energy always gets converted into thermal energy

What percentage of energy is converted into useful energy?
It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.

Does efficiency indicate how much energy a machine wastes?
When expressed as a percentage, 100% minus percentage indicates the waste percentage.
What is waste-to-energy?
waste to energy (wte) is the process of creating energy in the form of electricity or heat from waste sources.
Does geothermal energy leave waste?
No, geothermal energy has no waste.
When you do not waste energy you do what to energy?
The word "conserve" basically means "not waste" (or "not use").
What is waste thermal energy?
Waste thermal energy refers to thermal energy caused by friction. It usually a waste product that results when energy changes form or performs work.
Why are cows so inefficient at converting grass into beef?
Grass, which is eaten by the cow, is used as an energy source for building and repairing body tissues like muscles, metabolizable energy, reproduction, etc. Thus grass doesn't go directly into meat production of the cow, which is why it seems like the cow is "so inefficient" at converting grass into meat. Grass is also a coarser plant material and is not a concentrated ration, which compounds the reason for grass being "inefficient" at being converted into meat. Typically 20% of what the cow consumes of grass and roughage is used as energy. The other 80% is released as "waste" back to the soil for plants to reuse and get their fertilizer from. Quite frankly, if you want something more efficient than the cow, the man-made combine-harvester is the most efficient machine at harvesting grasses. It utilizes 90% of the grass harvested "converting" it into grain. But by no means will you get meat from it.

What we energy that is not useful?
Waste energy
