The direct source of energy for phototrophs is light. They use light energy to convert carbon dioxide and water into glucose through a process called photosynthesis.
In fission reactors, which is the only practicable source of energy at present, it is the fission of the nuclei of uranium and plutonium which produces the energy

Energy released from movement of protons through ATP synthase energy released from movement of protons through ATP synthase is the most direct source of energy in this case.
A battery is a chemical source of energy that produces direct current, DC. Some are rechargeable; some are not.

Most of my energy comes from electricity, which powers my systems. This electricity is typically derived from a power source such as a battery or a direct connection to a power outlet.
The direct source of energy in a cell is adenosine triphosphate (ATP). ATP is produced through cellular respiration, which converts nutrients from food into a form of energy that the cell can use to carry out its functions. ATP releases energy when its phosphate bonds are broken, providing the necessary energy for cellular processes.
ATP another word for energy.
Electricity.
