Uranium, nuclear energy, electrical grid, lithium and copper have been added to my list

Electrification will continue to increase, and that requires not only the production of electricity, but also the setup of all of the electrical infrastructure. AI runs on electricity, data centers need electricity and strong demand for electric lithium-battery powered vehicles (EVs) is here to stay for at least another decade.

You can invest in them using your favorite broker - there's plenty of ETFs, ETCs and equities.

For Uranium and nuclear energy - there are several ETFs that give you exposure to producers, distributors and infrastructure (e.g. nuclear plant maintenance).

Electrical grid investments can be done by acquiring equity in companies that expand and maintain it.

Not recommending any particular investment instruments, but the attached image provides you with a starter list.
