Where do spark plugs get power from?

ignition coil
In terms of operation, the spark plug is connected to the high voltage generated by an ignition coil (by way of a conventional distributor or by way of an electronic means). As electricity flows from the coil, a voltage difference develops between the center electrode and ground electrode on the spark plug.

What happens if I dont replace my spark plugs?

Spark plugs will depreciate over time, so various engine issues will arise if they are not replaced. When the spark plugs do not generate the adequate spark, the combustion of the air/fuel mixture becomes incomplete, leading to loss of engine power, and in the worst-case scenario, the engine will not run.
