Where is the 'cloud' storage stored? Cost in energy? Can you tell that I am trying to understand what 'cloud storage' means?
As Cicero said, “Gratitude is not only the greatest of virtues, but the parent of all the others.”
The "cloud" is simply a bunch of computers which store data and which are connected to other computers. That network can be the Internet or can be a local/private network (say, within a corporation or within a building or campus).
The "cloud" name came about because the specific location of the data that is stored is indeterminate to people using the data. Your device (computer or phone or tablet or ATM or cash register) manages that. The data (or even an app) simply is available through the device you're using, and whether it's coming from a computer near your home or one in Sao Paolo, Brazil, is of almost no consequence to you. Cloud data (and apps) often is replicated in various locations for many reasons: redundancy (not just one "golden" copy of the data but multiple instances of it kept in sync), response time (generally faster when the computer containing the data or app is closer to you), local language or content requirements (think Chinese versions of Google), etc.
Energy use? It can be considerable, though computers have made big strides in how much energy they use. The old joke used to be that a computer could also double as a furnace in a small home; those days are long gone. While rooms full of computers and storage devices do require cooling, it is orders of magnitude less than was needed 10-20 years ago (though the number of those devices keeps going up on an absolute basis).
Google, for instance, is said to have at least two million "servers" (though some of them exist as just a single board in a rack full of single boards or even as just a software program that emulates a physical computer). Microsoft is said to have about a million, to serve up OneDrive data and Microsoft (Office) 365 and email and its other products. Even the Fortune 100 company I worked at had more than 10,000 servers when I left nine years ago, many of which were either "blades" or virtual, not discrete boxes sitting on desks or tables. Not all of these were cloud servers but that gives you an idea of the population. Mining for cryptocurrencies like Bitcoin was estimated in 2018 to use about 1% of all the electrical power in the world; today there are 8733 nodes working away at mining Bitcoin (for our purposes, they can be considered cloud servers though some of them actually are boxes sitting on tables, which are inefficient cloud storage devices).
Does that help?

I never thought much about what the "Cloud" was, but I found Steve's explanation super interesting. Thanks!
I think in my technologically-naive mind, I almost took it literally! When I look for a document that's backed up in my cloud, I almost picture it descending from the heavens.
A lot about current technology, like cell phones and internet, is so mind-boggling. If we thought it would have been hard to explain to someone from the 19th century what a 1950s television set is and how it works, how would we ever explain uncountable bits of data flying through the "air"?

That first comment is mind-boggling to me. The mask isn't permanently affixed to one's face, after all. It's generally not worn at home, and with luck, the pandemic will be over in time. Cluelessness? Selfishness?

Comment: This article completely fails to consider the costs of mask-wearing. There's a reason why we don't do this. It impairs our quality of life. We like to feel fresh air on our faces. We like to go out and see people. We like to be able to talk to people unencumbered. We like to be able to see people's expressions, their smiles.
Sure, make a judgement about the relative benefits and harms of mask-wearing. But don't purport to be writing some kind of rational appraisal while completely ignoring the obvious loss of quality of life which universal, permanent mask-wearing would entail.
