A noise dampening energy efficient circuit board includes a carbon material layer for dampening electromagnetic interference between surface mount components and trace patterns of the circuit board. One or more ground plane layers are arranged relative to the carbon material layer to cooperatively dampen and repel noise of varying frequencies. The positioning of the carbon material layer with respect to the ground plane layer enhances the ground plane operation. Glass fiber material layers and other insulating dielectric layers are disposed at particular locations within the noise dampening energy efficient circuit board. The carbon material layer and the ground plane layer dampen electromagnetic noise, thereby permitting energy saving design considerations, increasing energy efficiencies and reducing power consumption. Mounting posts of the surface mount components include insulating sleeves to selectively insulate different layers of the circuit board from surface mount components. Methods for constructing and using the circuit board are also disclosed.
