Why is there a crisis if "energy can neither be created or destroyed"?

Scientists say that energy can neither be created nor destroyed, so therefore it is impossible for there to be an energy crisis.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
