If energy cant be created or destroyed why are we concerned about running out of energy?
There are TWO important laws about energy; you need to understand them both. They are known as the laws of thermodynamics. Actually there are a few more, but the first and second laws are extremely important to understand this question. If you ONLY understand the first one, you will only get an incomplete picture.* First Law of Thermodynamics: This is basically conservation of energy.
* Second Law of Thermodynamics: This can be expressed in many different ways; as a simple introduction, let's just say that useful energy can - and will - convert into unusable energy. This happens all the time, and is unavoidable.
For example, once a car uses up its fuel, the energy that was originally in the fuel is still out there somewhere, but in a "less concentrated", and utterly unusable, form. Among other things, the tires and the road have been heated up a bit.
What else can I help you with?
Is a true statement A. Energy can be destroyed but not created. B. The total amount energy in the universe changes rapidly. C. Energy can be created but not destroyed. D. Energy cannot be created?
C. Energy can be created but not destroyed. This statement aligns with the law of conservation of energy, which states that energy cannot be created or destroyed, only converted from one form to another.
Can energy be destroyed and created?
no energy cannot be created nor destroyed but it can change form
Energy is never or .?
Under most practical circumstances, energy can't be created or destroyed.
in natural (closed) systems, both energy and matter can change forms but cannot be ---- or?
Created or destroyed
Can energy get destroyed?
Energy cannot be destroyed according to the law of conservation of energy, which states that energy can neither be created nor destroyed, but it can only be transformed from one form to another. This means that energy can change from one type to another, but the total amount of energy remains constant in a closed system.

Can energy be destroyed and created?
no energy cannot be created nor destroyed but it can change form
What does it mean that energy is neither created nor destroyed?
Energy is cannot be created nor destroyed it can only be moved.
How is static energy created?
static energy obviously can not be created or destroyed
How is energy created problem?
energy is not created or destroyed. only transformed.
How energy created problem?
energy is not created or destroyed. only transformed.
Energy is never or .?
Under most practical circumstances, energy can't be created or destroyed.
Is it true that energy can be created or destroyed?
No. The first law of thermodynamics states that energy may be neither created nor destroyed.
What is neither created nor destroyed in a chemical change?
Energy is neither created or destroyed.
in natural (closed) systems, both energy and matter can change forms but cannot be ---- or?
Created or destroyed
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.
Can energy be created and sometimes destroyed?
No. The laws of conservation of energy dictate that energy can neither be created nor destroyed. Mass and energy are equivalent, so energy can only change forms.
