It has been shown that the efficiency of wires, cables, transformers
and electric motors can be improved significantly by using more
copper. By upsizing the cross-sectional area of copper conductors
in electrical equipment, less energy is wasted in the form of
heat generated, commonly referred to as I2R losses.
More efficient electrical equipment generates energy and monetary
savings which are quite significant. A typical payback for the
higher initial material cost of copper is less than two years.
More importantly, the savings continue to compound throughout
the service life of the equipment. Another advantage is that cooler-running
equipment will last longer.
Since electric motors consume over half of the electricity generated
in Canada each year, considerable energy savings can be realized
by using high-efficiency electric motors.
