I don't know what situation you are thinking of. The use of energy does correspond to doing work. You may be thinking of sitting quietly in a chair reading, not using any energy yourself (apart from your own internal metabolism), whilst your heating system keeps you warm. It may seem that no work is being done, but in fact your surroundings are losing heat continuously to the external of your house. That flow of heat is equivalent to mechanical or electrical energy through the relation 1 calorie = 1 Joule, or 1 BTU = 1055 Joules if you like BTU's. So even if mechanical work is not apparent, your use of heating BTU's is in effect doing work.

If this does not answer your question please submit another one but try to specify what situation you are thinking of

Potential energy is energy related to a position. If you put an object to a higher position (pushing it against the force of gravity), it will have more potential energy. If it falls down, this energy can again be converted into another kind of energy. While the object is high (say, on a shelf), the energy is stored as potential energy.

Having said that, one could nevertheless argue that all energy does involve motion somehow, on some scale. Thermal energy (heat) involves motion of the individual atoms and molecules. Nuclear energy involves the motion of subatomic particles. Chemical energy involves the motion of bound electrons between atoms. Electromagnetic energy (including light) involves the motion of photons. Electrical energy, by its very definition, involves the motion of free electrons. Acoustic energy (sound) involves the periodic motion of air (or other medium) molecules as waves pass through them. Even potential energy had to invovle motion at some time in order to position an object such that it now has potential energy.

Lost: no. Used up: yes.

To be more precise, energy can't be destroyed - the total amount of energy remains constant. However, it is possible to convert useful energy into unusable energy. In fact, this happens all the time.

nope, some energy's do not require motion!

### Can energy be used up or can energy be lost?

Energy isn't "used up" but instead is converted into different forms like heat (thermal) and motion (kinetic) but when talking about an object we say the object has lost or gained energy.

### How energy is lost biofuel?

energy is lost in Bio-fuels by the energy and the fuel used in biofuel to burn heat

### How is energy lost in biofuel?

energy is lost in Bio-fuels by the energy and the fuel used in biofuel to burn heat

### What happens to the remaining energy that is not used for life processes or lost as heat?

what happened to the energy that is not stored in your body

### Energy flow in an ecosystem is not cyclic because energy is?

lost as heat or used

### What happens to the amount of energy as you go up the energy pyramid?

Basically only 1/10 of the energy from the previous organism is absorbed into the body of the consumer while the other 9/10 is burned up when used for energy by the previous organism. If there is some grass with 100 energy and it gets eaten by a herbivore, the herbivore only receives 10% of the ORIGINAL energy (so the herbivore will have 10 energy.) The animal that will eat the herbivore will only receive 1 energy from the ORIGINAL energy source. The next consumer of the previous organism will only get 0.1 energy from the ORIGINAL energy source and so on.

### What happens to the energy level as you move up the energy pyramid?

10% of energy is lost as you move from 1 level to the next. So at the end 90% if the energy will be lost as heat.

### 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 do living things use to make energy?

They eat to make up the energy they lost

10 percent

### Where does the energy go that is lost in the energy pyramid?

Only the energy stored as biomass (stuff that the next organism up eats and successfully absorbs) makes it up to the next layer of the pyramid. The rest i lost because the animal doing the eating doesn't absorb all of the energy in the food, the animal moves around expending energy, some (quite a lot actually) is lost as heat in warm-blooded animals, etc. In fact very little of the energy absorbed by one layer of the pyramid through eating makes it up to the next layer.
