How Do We Inventory the Materials Needed To Build Wind and Solar Farms?New Database Quantifies What the Country Needs
is the result of a collaboration between NREL, which led the effort, the U.S. Department of Energy’s Wind Energy Technologies Office and Solar Energy Technologies Office, which funded the project, and Oak Ridge National Laboratory, Sandia National Laboratories, Lawrence Berkeley National Laboratory, and Arizona State University.
“We used the REMPD to compute the quantity of materials needed to support future deployment scenarios for wind energy in the United States,” saida wind energy analyst who contributed to the REMPD. Those scenarios consider decarbonization goals and current policies that affect wind energy deployment, including the Inflation Reduction Act. The team evaluated how demand for new wind power plants might impact critical material needs in the United States from 2020 to 2050.
Despite these challenges, the research team found that annual U.S. wind energy deployment between 2020 and 2050 would require less than 5% of what the world produces today for most identified common and vulnerable materials. But it is not all good news. In the “High Deployment” scenario, demand for the rare earth metals dysprosium and neodymium could exceed 10% of current global production by 2042 and demand for carbon fiber and balsa wood could surpass current global supplies before 2030.

New Database Helps Quantify Materials Needed to Support Growth in Wind EnergyReaching the Biden administration’s clean energy goals will mean significant expansion of wind energy. But constructing these wind energy facilities requires more than just ample wind. Energy technologies are built from a variety of raw materials, like concrete and nickel. And supplies of some of those materials are not as plentiful as the wind that […]
