Talking about electricity. How much money do you need for finding let's say 1 trillion hashes per second?
Depends on your power price, ASIC price, ASIC type and "other costs" (shelves, network gear, cabling, S&H, taxes,...)
I'll do a quick guestimation for one of the newest, general available ASICs (usually, the newer the asic, the more hashes/energy unit).
An S19 pro hashes @ 110 Th/s
That's 110.000.000.000.000 hashes per second (110 trillion hashes/second)
It consumes ~3250 Watt . I'm not taking the A/C into account tough, nor the overhead by other elements of your mining room.
It costs ~$2600, plus a PSU of $90, S&H, import taxes... I think a ballpark figure would be $3500 for a "complete" S19 pro delivered on your doorstep.
Now, you can plug these numbers into a calculator like

But it would still take ~460 days to ROI at current diff (which might rise every ~2 weeks), current price (wich might drop every moment) and at current block reward (which will halve in ~20 days)
My own (more realistic) numbers would be:

If i would run such a miner, i'd mine at a net loss of about $6/day, meaning my electricity cost would be $6 MORE than my income. Each day i'd have a net loss, and it would only get worse after the halving
