What is the energy transformation that is similar in the human body and in fossil fuel electric energy plants?

The energy conversion goes from chemical energy stored in the fuels to heat energy as it burns which is converted to kinetic energy as it drives large turbines and finally this is converted to electrical energy. The problem with burning fossil fuels is their effect on the environment.

When a body falls, its potential energy gradually gets converted into kinetic energy. On reaching the ground, the whole of the potential energy of the body gets converted into kinetic energy.

Energy gained from burning fossil fuels is converted to electricity and heat in commercial power plants. When fossil fuels are burned carbon and hydrogen react with oxygen in air to carbon dioxide (CO2) and water (H2O).

as we gain mass the force of gravity on us increases.
