IIRC there was a climate simulation
issued in 1995 that while not
explicitly stating an 80 % contribution factor for renewable energy sources, did qualitatively suggest something on that

While they don't
explicitly tie TrueDepth camera production
issues to any reasoning for the trials — large tech companies do
order test runs for their products at their contracted plants on a routine basis — it's the
issue freshest in mind for any stumbling blocks going forward.
