The reason is related to the fact that the laws of physics don't change over time. For more information, read the Wikipedia article, or some other source, on "Nöther's Theorem" also spelled "Noether's Theorem". Be warned - you'll need some pretty advanced math to understand all the details. But in summary, each symmetry in physics - in this case, the fact that physical laws don't change over time - is related to a conservation law - in this case, conservation of energy.
You cannot destroy or create energy: you can only convert it into other forms For example: fuel into heat energy.
energy cannot be air, cannot be destroyed, cannot be created
The quote is "energy cannot be created or destroyed, it can only change forms"
no energy cannot be created or destroyed
Conservation of Energy.
Energy cannot be created or destroyed. According to the Law of Conservation of Energy, energy is always conserved, though it can change forms (eg, from potential energy to kinetic energy, or from chemical energy to heat energy).

How was energy created at the beginning of time? If energy cannot be created nor distroyed then how did it originate?
energy cannot be destroyed or created, thatt all i know
no energy cannot be created or destroyed
energy cannot be created or destroyed
Conservation of Energy.
According to the Law of Conservation of energy, energy cannot be created or destroyed.
There is nothing like that. energy cannot be created
