Is it always easy to collect wasted energy and use it?
Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.
How do you interpret a sankey diagram?
It is a means of saying how much energy is useful and wasted. Has the appliance represented on the diagram got a high or low efficiency; i.e, is there a larger proportion of useful energy compared to that of wasted energy, making the it more efficient. Can you work out the efficiency as a percentage using your knowledge of the equation, Efficieny = useful energy out/ total energy in?
What percentage of the commercial energy used in the US is wasted?
84% is wasted.
Is a boiling kettle useful or wasted energy?
Wasted, unless you specifically want to produce a lot of steam.
Headphones useful and wasted energy?
usful energy will be that it make sound for the person to hear through it

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.

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 you is energy that is not useful?
wasted or non-applied energy. Not sure of your question, poorly worded.

What is useful and wasted energy?
Useful energy is energy that can be converted to any other type of energy. Wasted energy is no longer available to be converted - usually because it got spread out too much, or because it got converted to heat. Heat can be partially, but not completely, converted to other types of energy.
What is the useful energy from an electric drill?
sound, also heat
What can be done to improve the power factor?
Power factor is the percentage of actual useful energy obtained from an electrical device as opposed to the wasted energy lost to impedience of a circuit. ie heat, voltage drop. Improvement is to raise this percentage to as close to 100% as possible.
What role does friction play in energy transformations?
In many cases, energy is wasted due to friction - meaning that useful energy is converted into unusable energy.
