    What is this publication and who finances it because this section is incredibly sus:

    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.

      I’m not defending the article, but I think most overhead power lines are aluminium, which is probably good as it’s abundant compared to copper.

      1. The article is shit, the study is about copper used for reducing fossil-fuel power generation. It is basing the projected use of copper on windmills and especially large batteries.

      2. Those high-powered and long distance power lines are made aluminium and steel.

        1. Distribution doesn’t just include long distance distribution. It includes all the wiring between transformers and houses and all the internal wiring of the house and all the devices inside etc.

      The original study abstract is a little more clear. The main concern is grid storage batteries and EV batteries.

      Given that the sharp increase in copper demand is primarily driven by batteries, the extra copper needs for electrification can be significantly reduced if the need for electrical storage is minimized. This can be achieved by generating electricity through a mix of nuclear, wind, and photovoltaics; managing power generation with backup electric plants fueled by methane from abundant resources of natural gas; and transitioning to a predominantly hybrid transportation fleet rather than fully electric vehicles.

        Or you use pumped hydro, or compressed air, or gravity batteries, or any of the other energy storage technologies that aren’t chemical batteries.

      Your argument against the article that talks about copper usage is founded on incomplete knowledge of where copper is actually used?

      🤦

        It’s founded on the article not making a cohesive argument. Current copper usage is primarily in consumption and distribution, not generation.
