Copper use is not carved in stone. Hybrid cars, which pair small batteries with gasoline engines, need far less of the metal than fully electric vehicles.

Power grids that mix nuclear, wind, solar, and a pinch of natural-gas backup can slice the copper bill dramatically compared with battery-heavy systems.

“First of all, users can fact-check the study, but also they can change the study parameters and evaluate how much copper is required if we have an electric grid that is 20% nuclear, 40% methane, 20% wind, and 20% hydroelectric, for example,” Simon said. “They can make those changes and see what the copper demand will be.”

Like you think we can transition to an increasingly electrified world, where all power comes from electric utility lines, and you think our copper usage will be ... just in renewable power plants?

This reads like straight fossil fuel propaganda. In an electrified future the majority of copper use comes from distribution lines and products that use electricity not the type of power plants generating electricity.
