Basically, always. There is no known way to create energy where there was none before (or to increase or decrease the amount of energy).

What law says in chemical change energy is neither created or destroyed?
Scientists call this law the law of conservation of matter
Law that states that energy cannot be created or destroyed?
The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.
How is the law of conservation of energy relate to energy transformation?
The law of conservation of energy states: "Energy can neither be created or destroyed, only changed in form." Energy transformation is changing it's form. Note: This law only holds in Newtonian physics. I Einsteinian physics is isn't valid.
Of thermodynamics is a restatement of the law of conservation?
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
What states have energy laws that state that energy can not be created or destroyed?
Law of conservation of energy. Energy can't be created or destroyed is the basic statement of the law of conservation of energy.
What law of the scientific rule states that energy cannot be created or destroyed?
The law of Conversation of Energy

Law of conservation of energy. Energy can't be created or destroyed is the basic statement of the law of conservation of energy.
Why the law of conservation of energy can mean that you do not have unlimited sources of energy?
That is because the law of conservation of energy states that you can not create new energy.
How is friction different from the laws of conservation of energy?
There are no "laws" of conservation of energy, just the law of conservation of energy. The existence of friction doesn't change anything - the law of conservation of energy still holds.
What law states that energy is never created or destroyed?
That is called Conservation of Energy. It is also known as the First Law of Thermodynamics.
What is th law of energy called?
the law of conservation of energy
Is the law of conservation of charge the law of conservation of energy?
No, those are two separate conservation laws. Charge is not energy. They are entirely different things.
How does gravitational contraction generate energy?
Obviously no new energy is created - the Law of Conservation of Energy is still valid. What happens is that potential energy is converted into some other kind of energy, especially heat.
