Question:

People often use the term energy crisis, implying that we are running out of energy. How can this be if energy is conserved? If we are not running out of energy, what are we really running out of?

Law of conservation of energy

Law of conservation of energy may be defined as "energy is neither be created or nor be destroyed it converts from one form of energy to another" form of energy.

Answer and Explanation:

In winter season when we use the heater in the room the electric energy is converted into the heat energy and the heater warms up or increases the surrounding temperature but this dissipated energy by the heater cannot be reuse in useful work than actually this type of dissipated energy we are running out.

It is impossible to convert whole low-grade energy to high-grade energy. This is also defined by the second law of thermodynamics.
