Glass is made of sand and oil.
Sand is apparently in shorter (not short) supply. Oil isn’t. I think it’s a different world than the 1994 article you link to

1) Oil was less expensive, inflation-adjusted, in 1994 than it is today ($30/bbl) 2) Only very specific sand is in short supply today (construction and fracking sand, neither of which is fungible with arbitrary sand) 3) Glass is made of natural gas.
