Is heat a unusable energy?
Heat, by itself, is unusable. It is the heat difference that makes it usable.
Do machines use power to perform work in a more energy efficient manner?
Yes, a simple machine can create friction, and friction can create heat. You are converting mechanical energy to thermal energy.
What is the difference between usable energy and total energy?
The difference is the unusable energy.
Is Energy can be change completely from one form to another?
Usually not; some energy is usually wasted. Although energy can't really be destroyed, part of the energy is converted to an unusable form.Usually not; some energy is usually wasted.

What happens to the energy not passed on to the next level?
It is lost, in the sense that it is converted into unusable energy.
Does the second Law of Thermodynamics contradict the First Law?
Not at all. The First Law states that energy is conserved - you can't create energy out of nothing, or make it disappear. The Second Law distinguishes usable from unusable energy, and states that the amount of unusable energy will increase over time - but the total (usable plus unusable energy) will still remain constant.Not at all.

How do machines create energy?
It is wrong to say machines create energy. Machines have to be given energy to make them effective. This could be electric energy, solid liquid or gaseous energy, thermal energy, mechanical energy (like a flywheel for example). It may be possible to design machines which will search for their energy by themselves, some robots may already have achieved. Remember we humans are also machines, but we get our energy from digesting food.
Can energy be destroyed but not created?
Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.

An airplane changes energy into different forms The total amount of energy does not?

Can energy be regenerated?
According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.

What limits the use of wind as a major source of energy?
Turbines and generators in the wind machines create electricity.
What happens to the energy not passed on to the next level?
It is lost, in the sense that it is converted into unusable energy.
What is a quantity measuring energy unusable because of disorder?
Entropy
