A power cord assembly is disclosed. The assembly can include a plug at a first end of the power cord configured to be connected to a power source, a connector part at a second end of the power cord opposite to the plug and configured to be connected to an electronic device, one or more electrically conductive wires extending from the plug to the connector part, one or more insulators surrounding the one or more electrically conductive wires, and an outer jacket extending from the plug to the connector part and surrounding the one or more insulators. At least one of the plug, the connector part, the one or more insulators, or the outer jacket can include a polybutylene terephthalate (PBT)-polytetramethyleneoxide (PTMO) block copolymer having hard block and soft block segments, wherein the hard block segments comprise PBT and the soft block segments comprise PTMO. The hard block segments can include a first renewably sourced polymer obtained, at least in part, from a first bio-renewable source or a first polymer comprising a chemically recycled monomeric unit obtained, at least in part, from the first bio-renewable source. The soft block segments can include a second, different renewably sourced polymer obtained, at least in part, from a second, different bio-renewable source or a second polymer comprising a chemically recycled monomeric unit obtained, at least in part, from the second, different bio-renewable source.
