Just had that thought, from the contract with my electricity supplier I get here 100% renewable energy. How about you? Or do you run on solar panel? Might be an idea for an Label „decentralised cloud hosting on renewable energy“ is there demand from customers?

I have solar panels, but they do not provide enough energy for my use. That is partly intentional (partly because it would have been a problem fitting more panels) - while the government will “store” excess energy for me and let me have it back for 0.07EUR/kWh, this can change for the worse at any time. So, my solar panels do not make that much excess power.
Other than that, I do not pay extra for “green energy” - I’ll choose whatever is cheapest. If 100% coal power was an option and 0.001EUR/kWh cheaper, I’d be using that. Or, you know, if it was cheap enough to have a coal fired boiler and a steam engine connected to a generator…

I live in Hungary and run my whole house on solar. We have a strange (I would say politicaly motivated) energy pricing system: I have yearly saldo on electricity. So the service provider company takes my excess solar generated power during daytime/summer, and I can take it back during nighttime/winter for free.
With my 11kWp solar system, I have zero electricity bill even though we have heat pump heating/cooling in the house and an electric car what we charge only at home.
Running the nodes and their power consumption is peanuts considering my whole year energy balance.
Sounds good, but on the other hand we have a huge deficit in democracy.
Well, that is an other story…

That’s great while it lasts. I have to pay 0.07EUR/kWh to get the “stored” energy, but that as well can change at any time (as in, once the government figures out that there are enough solar panels installed and that it is losing money on this).
So, my 10kWp solar panels usually make less than what I use and the excess is rather small (only enough for maybe one hour if the day was very sunny).
OTOH, in the summer the panels make more electricity, but my AC uses more electricity as well, so at least that sort-of works together.
I would love to have that price here in Germany. I pay like 0.35€/kWh😢
But we are currently building solar on the roof with battery storage, so I hope it will make it better

$.52/kWh here. Installing solar makes zero sense because you can’t really sell electricity back to the grid, unless you grandfathered Into old tariffs. Our grid has plenty of solar generation, but not enough storage. They build battery stations but it’s not enough. So electricity is super expensive across the board. And installing battery at home — never even breaks even.

Normally I pay ~0.26EUR/kWh during the day and ~0.16EUR/kWh at night or weekends.
0.07EUR/kWh is the “storage” price - when my solar panels generate excess energy, it is “stored” by the government and later I can get it back for 0.07EUR/kWh.
In that case shouldn’t solar panels get ROI very quickly? At least if you size them so that they do not generate too much excess energy.

Yes, with high energy prices you normally have ROI real quick. Even if you can’t sell to the grid.
Solar is super cheap and has a long lifetime.
And if you get battery storage for cheap too, you can be more independent from the power grid.
I think all node operators are powered by renewable energy (food) 
But if seriously, we have had this article a long time ago (since v2):
