wind turbines

Commercial, industrial and utility sectors throughout the U.S. are installing photovoltaic panels and building high-megawatt wind farms to generate clean, efficient power to meet our rising energy demands. These alternative energy sources (sun and wind) are free and plentiful, and the energy plants required to harvest and deliver this energy do not continuously generate carbon or other emissions. Such alternative energy plants are clean and reliable.


  • Video Icon Oak Creek Wind Energy
    Oak Creek Energy Systems Inc. is a pioneer in gigawatt-scale wind energy with its long-term expansion of wind power capacity in the Tehachapi-Mojave area of California. This video describes a somewhat unique case where one wind farm was constructed to serve one major customer, and explores the infrastructure necessary to keep the turbines up and running.

    This report analyzes copper’s growing use for renewable wind energy through 2027. Between 2018 and 2027, it’s estimated 48,721 MW worth of wind energy installations will be constructed with an estimated demand of 4.76 tons of copper per MW. 
  • SOLAR: North American Solar PV Copper Content Analysis [PDF]
    This report presents a forecast for the North American solar PV market through 2027. Between 2018 and 2027, North America is expected to install 137 GW of residential and commercial & industrial solar capacity as well as 125 GW of utility-scale solar. This forecast also estimates during the same timeframe nearly one million tons of copper will be needed for this growing technology.
  • Current and Projected Wind and Solar Renewable Electric Generating Capacity in the Domestic Market 
    The Copper Development Association conducted a study and examined renewable energy (RE) production, including land-based and offshore wind; residential, commercial and utility-scale photovoltaic installations; concentrating thermal-solar electric plants; and geothermal plants.

    This short white paper by John Paschal, Jr., P.E. of Paschal Engineering, explains the basic principles of conductor temperature in sunlight and emphasizes the importance of Table 310.15(B)(2)(c) in the NEC.

Case Studies


Copper's electrical and thermal conductivity and high resistance to both atmospheric and aqueous corrosion makes it so valuable in solar energy systems.

Solar PV by the Numbers

60-70%: compounded annual growth rate of residential and commercial sectors. Utility scale PV installations have quadrupled since 2008.
