Here's a link to a talk from an associate professor doing an estimation of how much metals are needed to switch to renewable energy: https://youtu.be/MBVmnKuBocc?t=2406
Definitely not a panacaea, and super-inefficient, but that's OK if we're just using it for storage/transportation.
What experts? Power to gas has been really energy inefficient with little sign of improving from what I know. It can't really compete with pumped hydro even where pumped hydro makes less to no sense it seems.
Imagine if all the passengers on the Titanic had nuclear weapons. That’s the situation we’re in. And there are no lifeboats.
We can adapt to climate change. We can create new (clean!) energy sources.
Solar is getting more efficient every year. There are new storage solutions appearing every year.
As TFA says, despair is not the answer. We can (and will) overcome all these problems.
Don't make the mistake of confusing energy use with quality of life.
People like to make such alarmist statement around standard of living but we should instead ask ourselves what makes for quality of life.
A good example is planned obsolescence in technology: it greatly increases energy usage and pollution without making consumers happier (on the contrary they hate it)
