Definition
电源 (diànyuán) means a specific power source or supply for a device—the physical thing that provides electricity (like a power cord, outlet, or battery). In contrast, 电力 (diànlì) is electrical power as an abstract resource or utility (e.g., electricity supply to a city), while 能源 (néngyuán) is energy in a broader sense, including fuel, solar, and wind.
