Since copper has the highest electrical conductivity of all industrial metals, it is not surprising that well over half of all copper produced in North America is consumed in electrical applications. For example, in an average, 2100 ft2 (195 m2), single-family house, you will find about 195 lb (89 kg) of building wire. A modern automobile has over 40 lb (18 kg) of copper for electrical applications, a figure that is growing quickly as vehicles add more electronic components and automated features.
