What type of energy do computers utilize?

Computers primarily utilize electrical energy to operate. This energy powers the components within the computer, including the processor, memory, and storage devices, enabling them to perform computations, run software applications, and process data. Electrical energy is converted into other forms, such as thermal energy, when components like the CPU generate heat during operation. However, the core operation and functionality of computers rely on electrical energy as the fundamental source. Other forms of energy, such as mechanical and chemical, do not directly drive the primary functions of computers, making electrical energy the correct choice.
