Answer: because they cannot be produced in the body and must be consumed from outside sources
Renewable energy is generally defined as energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.
A non-renewable resource (also called a finite resource) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. An example is carbon-based, organically-derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas.

The ÷ represents the triple bond.
C1 is triple bonded to C2, as well as bonded to a H.
C2 is triple bonded to C1, as well as bonded to C3.
C3 is bonded to 2 H's, as well as C2 and C4.
C4 is bonded to C3, as well as 3 H's.
