Economics

• Incremental copper use improves equipment energy performance
• The value of copper supports end-of-life recycling
• Copper saves manufacturing and installation costs
• Conductors are a very small component of electrical system lifecycle costs

Environmental aspects

• Copper recycling
• Copper drives the recycling chain due to its economic value
• Copper saves on other materials through its compactness (typically 20%)
• Copper recycling enables precious and speciality metals recycling
• Upsizing copper cable is overwhelmingly positive
