Do glass doors on a fireplace reduce the amount of warm air that get wasted up chimney?

When a fireplace is not being used... glass doors are not a good way to stop cold air from exiting the chimney. The first thing that needs to be done is the fireplace damper should be closed to prevent this heat loss. If the damper is not-functional or absent a chimney balloon or chimney top damper can be installed to stop the heat loss.
When there is a fire in the fireplace...Fireplace glass doors reduce the amount of already heated interior air that the fireplace has access to. So it does slow down the inside heated air from being cast up the chimney with the fires combustion heat, but glass doors do not stop this heat waste completely. Fireplace glass doors also inhibit the only usable heat the a fireplace produces (radiant heat) from coming into the living area. Standard open fireplaces and fireplaces with glass doors are notoriously inefficient at heating the home. According to the US Department of Energy using a fireplace in the winter will actually make your heating bill go up by 10% on average.

Do glass doors reduce the amount of warm household air that gets wasted up the chimney?
I cannot see how, the two are parts totally unrelated systems within your home.
Heat given off by fire in a fireplace is an example of what?
Heat cast forward out of a firepalce is called radiant heat and it the only usable heat that a fireplace can create The wasted heat that a fireplace creates is called combusion heat that rises up the chimney.
What does wasted energy add too?
Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe. The wasted energy is related to entropy - one way to express the Second Law of Thermodynamics is to say that there are irreversible processes (in terms of energy), another is that "entropy increases". However, entropy is not energy; it is not measured in Joule, but in Joule/Kelvin. In any case, you might say that when energy is wasted, entropy increases.Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe.

Why is a machine not 100 percent efficient?
Some energy (or power) is usually wasted. It is often possible to take measures to reduce it, but this can't be completely eliminated.Some energy (or power) is usually wasted.

How is paper wasted and How do you reduce consumption?
Paper is wasted whenever you throw away a page because of one mistake.Paper is wasted when you use 20 pieces of toilet tissue instead of 10.Paper is wasted when you use paper towels instead of a washable cloth.Paper is wasted when you print on only one side instead of printing double sided.You reduce paper consumption by not wasting paper (see the examples above)!
Why is the amount of that a machine does is less than the amount put into the machine?
In such a machine, the remaining energy is wasted to friction
What is a foodprint and how does food choice relate to the amount of land needed to support an organism?
foodprint is the amount of food wasted by a man
Is there wasted electricity when you turn off a ballast controlled flourecent light?
No, when it's off it's off. A very small and insignificant amount is wasted when you turn the light on.
What is the largest amount of wasted energy in a transfer?
The situation really depends on the specific type of energy transfer. However, it is quite common that most of the wasted energy is converted into heat energy.
How do induction hobs shorten cooking time?
Induction hobs shorten cooking time by allowing for more precise control of temperature. Induction hobs also reduce the amount of heat wasted while cooking, allowing more heat to be applied to the cooking vessel.
How can you make machines more efficient?
Reduce or remove friction. Ensure that the energy going in is not wasted due to unnecessary work or heat.
