Due to the many uses of copper in the green energy sector, here is a new thread displaying many of the Wind Energy projects taking place globally and electricity grid upgrades. The amount of copper required to roll out the desired outcomes will be tremendous. I doubt there will be enough copper to go around and will certainly see a shortfall of production over the coming years. Above-ground electricity grid is connected with aluminium/steel HVT cables to reduce weight & steel for strength between spans. If HVT is underground or a wind turbine then copper is used. Copper is still used for short interconnects above ground, as between the power line and a utility transformer, because it is less prone to work hardening and fatigue, allowing it to be disconnected and reconnected multiple times. Copper oxide is also more conductive than aluminum oxide, so connections are more reliable.

Here is a good article to read on US transmission grid & wind energy projects published 28/07/22.

MISO Lets Renewable Energy Genie Out Of Bottle With Biggest Ever Transmission Project.

MISO is the system operator for the electricity grid in 15 states in the nation’s midsection. It has just announced the biggest portfolio of transmission line projects ever proposed in the US, starting with a $10.3 billion investment in 18 new projects for the northern part of their territory.
MISO (pronounced em-EYE-soh) stands for Midcontinent Independent System Operator, an agency that oversees a grid territory that splits the US practically down the middle and reaches up into Canada.
MISO covers all of part of Arkansas, Illinois, Indiana, Iowa, Kentucky, Louisiana, Michigan, Minnesota, Mississippi, Missouri, Montana, North Dakota, South Dakota, Texas, and Wisconsin, and the province of Manitoba in Canada.
The states involved in the plan for 18 new transmission line projects are Michigan, Indiana, Illinois, Missouri, Iowa, Minnesota, and North and South Dakota. Several states in that region have already been pursuing wind powerhand over fist, and some recent activity in the solar power field indicates that the area’s solar profile is also on the move.
Our friends over at the Clean Grid Alliance estimate that the 18 new MISO projects alone will unlock 53 gigawatts in new wind, solar, hybrid, and battery-type energy storage projects. “[That’s] enough to power about 12 million homes and 213,000 jobs,” CGA enthuses. “About 120,000 jobs can also be estimated to result from the transmission work, so we can expect about 333,000 jobs total from the transmission work and renewable resource construction together.”
The 18 new transmission line projects are actually just Tranche 1 in a meticulously planned series of grid improvements outlined in MISO’s Long-Range Transmission Planning process.
$10.3 billion price tag for Tranche 1, Tranche 2 will also cover the Midwest Subregion, Tranche 3 will focus on MISO South, and Tranche 4 will “address the limitations on power exchange between the MISO Midwest and South Subregions.”
