The energy source is renewable. The harvesting infrastructure is not. And needing fossil energy and mineral extraction for buildout and sustain, neither of which are renewable.
I use Graphene OS and mostly/exclusively only open source applications.
They are supporting their government since Russia is under attack, but the war is unpopular. The government response is considered too weak, many want harder strikes, including against the West.
Careful consideration doesn’t work around thermodynamical limits very much, I’m afraid. When we move forward, we do not energy transition but rather add new atop the old: we never stopped burning classical biomass, coal or natural gas. Renewable energy is just a new thin layer on top. Depletion of mineral resources necessary for renewable infrastructure buildout and maintenance indeed does a number on the overall economics and energetics, but unfortunately in the wrong drection.

zfs is about data integrity rather than performance.
Do you know a heat pump which operates at 1400-1600 deg C?
Looking at glass, or cement. Do you know a heat pump that runs at up to 1600 C? So it’s just plain ohmic heating. And it’s a 24/7 process, so it needs electrochemical backup. Do you know what that does to your EROEI?
You can just look at primary photosynthetic productivity and HANPP to get an upper bound. Or average population of animals of our size, which is half a million IIRC as a lower bound. With corrective factors for ecosystem degradation, of course. My own estimate is less than half of a billion, without accounting for ecosystem degradation.
Make sure your data pool is well laid out zfs though.
If only that distinct species had a whole separate planet of their own, that’d be great.
How does a heat pump helps you firing Portland cement, ceramics, melting glass and metal, fixating air nitrogen? And these are all 24/7 industrial processes.
The balcony solar systems in Germany are cheap and plug-in-ready, no licensed electrician required. If you need one, the payback time is going to be much longer.
With whole house setup which is much bigger it make sense to invest in an EV and/or a heat pump. Few pay all that in cash, and now there is a bank in the loop.
If you aim for zero feed in you will need input from sensors like Shelly 3E and a controller that can deal with it.
In Germany many of them now do.
I use nVidia shield TV with a dumb video projector. I haven’t bothered with a custom launcher.
Yeah, it definitely won’t survive an 8 hour day.
Even i386 felt pretty speedy when compared to 8 MHz 68k.
