Depends on your motivation for mining. If it is purely for profit then your assumption is most likely correct though I've come to understand that you can profitably mine bitcoin at scale with sub 6 cent kw/h electricity. That of course assumes you have the space for industrial miners, the ability to deal with the sound (if air cooled) and heat dissipation even with immersion or hydro-cooled miners. The electricity is just one little part of the overall equation.

If you mine for more philosophical reasons and want to support decentralizing the hashrate and kicking in to help secure the network then that leaves a lot more wiggle room.

Here is my little garage Bitaxe and BitForge "farm". 15 to 20 TH/s depending on ambient temperature. I'm in Texas so the heat is a bigger issue for us than it would be for you.

I love seeing everyone's setups. It's early days for me so although I am very much interested in supporting the network, right now my goal is to just accumulate as much Bitcoin as possible. I may jump on a NerdQaxe++ if they run a sale and I feel like some retail therapy, but my hunch is I should just pump all income into BTC, not small-scale hardware.

Which pools do you mine in?

I solo mine to my own node and local instance of public_pool.io running on my Umbrel Home.

With your electricity rate you could dip a toe into the real thing by going with something like the Canaan Avalon Q. Good price point that isn't too loud, produce too much heat and generates a decent amount of hashrate relatively efficiently.
