Which energy source uses the most minerals?

Here is an excerpt from my Briefed by Data post Minerals for renewables:

A few things stand out. The first is the amount of minerals utilized for offshore wind, which is 50% more than for the next category, onshore wind. The second factor is the importance of copper in all energy sources. Figure 2 shows the copper price from FRED. Prior to 2004, the price remained below 3,000 per metric ton, and it has climbed around four to five times since then.
