Yes, in a power station the energy balance can be assessed, all the heat from burning the coal or whatever has to appear somewhere, either in the station output or in losses which can be accounted for.
The total amount of energy in a closed system remains constant according to the law of conservation of energy. Energy can change from one form to another, such as from potential to kinetic or thermal energy, but the total energy within the system remains the same.
The law of conservation of energy states that energy cannot be created or destroyed, it can only change form. However, it has been shown that energy can be converted into matter and vice versa. (that is the short answer. For more complete information study quantum physics and E = mc2)
umm it all depends on what it is transformed in to
The total energy doesn't change in such cases.
Mass and energy can never be created or destroyed, but can change forms. An exothermic reaction releases stored chemical energy and transforms it into heat, but the total amount of energy does not change.
No, energy is not produced. The total amount of energy doesn't change.
The total amount of energy in any closed isolated system remains constant, according to the law of conservation of energy. This energy can change forms within the system (e.g., potential to kinetic) but cannot be created or destroyed.
When an energy transformation occurs, the total amount of energy remains constant. Energy cannot be created or destroyed, only changed from one form to another. This principle is known as the law of conservation of energy.
The total amount of energy remains constant, but it is transformed from chemical energy in the match head to thermal energy (heat) and electromagnetic energy (light) when the match is lit. This is an example of energy conservation in a closed system.
The total amount of energy doesn't change in this case.

total thermal energy
We do not think it does change.
"Law of conservation" means that the total amount won't change.
"Conservation" means that the total amount of energy doesn't change.
The Law of Conservation of Energy
No. It just gets moved around. The total amount of energy stays the same.
The total amount of energy before and after a transformation will be the same. Energy may pass from one object to another object, or be converted from one type of energy to another, but the total amount doesn't change.
In physical changes, the total amount of energy before and after remains the same as no new substances are formed. In chemical changes, there may be a difference in the total amount of energy before and after the reaction due to the formation of new substances and the breaking or forming of chemical bonds.
In any transfer of energy or conversion of energy from one form to another, the total amount of energy does not change. The total amount of usable energy, however, always decreases.
It isn't entirely clear whether total energy is conserved in General Relativity, or whether the total energy is even clearly defined in all cases. But in general it is assumed that the total amount of energy doesn't change over time.
