# Why are most non-renewable energy resources burned?

Mar 2, 2016

Hydrocarbons ${C}_{N} {H}_{2 \left(N + 1\right)}$ represent a state of high electrostatic potential energy. In nature it is observed that almost all system tend to proceed toward a state of lower potential energy. High potential energy states are thus inherently unstable and systems would reconstitute themselves releasing the energy if they can settle in a new state of lower potential energy.
Deep under the Earth's surface where the temperature is found in the range of ${100}^{o} C - {150}^{o} C$, organic matter (kerogen) undergo thermal decomposition progressively over geological time periods to lighter hydrocarbons like methane, through a process called Catagenesis . The final product is simple hydrocarbons like Methane.
