I know this is a Buy European community, but when it comes to batteries, aliexpress is still your best bet. You can build your own or buy a pack that is ready to plug and play
Is nuclear really cheaper than renewables + batteries nowadays? I wonder if there are recent studies looking into it
Quick search points to this:
Levelized Cost of Electricity: which is a measure of the total cost of building and operating a power plant over its lifetime and expressed in dollars per megawatt-hour. [...] LCOE serves as a comprehensive metric that consolidates all direct cost components of a specific power generation technology. This includes capital expenditures, financing, fuel costs, operations and maintenance, and any expenses related to carbon pricing. However, LCOE does not account for network integration or other indirect costs
LCOE for advanced nuclear power was estimated at $110/MWh in 2023 and forecasted to remain the same up to 2050, while solar PV estimated to be $55/MWh in 2023 and expected to decline to $25/MWh in 2050. Onshore wind was $40/MWh in 2023 and expected to decline to $35/MWh in 2050 making renewables significantly cheaper in many cases
[...] Global weighted average levelized cost of electricity for newly commissioned utility-scale solar photovoltaic, onshore wind, offshore wind, and hydropower projects experienced a downward trend. The most notable drop occurred in utility-scale solar PV, which saw a 12% decrease from 2022 [in LCOE costs][...]
In contrast, nuclear power continues to face cost overruns and long construction timelines [...]

[Caveat: Below numbers are most likely not using LCOE]:
[...] In 2025, developers added 87 gigawatts of combined solar and storage, delivering power at an average of $57/MWh
By contrast, benchmark cost of a typical fixed axis solar farm increased 6% compared to 2025, hitting $39/MWh, while onshore wind reached $40/MWh and offshore wind climbed to $100/MWh globally [...]
If we aren't there yet, I still think we might see renewables + batteries as cheaper options in the short term.
I'd really like to see an LCOE analysis including batteries. If we naively assume LCOE costs for PV+batteries is the same as PV, we might already be there
Let us know how it goes. I love seen how these cases unfolds in the fediverse
As some people mentioned, it is a good idea to ID them first, and depending on the species, if they are parasitic, they can kill the tree or leave it weak enough to die from something else
Some species, even if you cut their visible stems, but leave the host trunk intact without treatment, they can regrow from embedded haustoria (specialized roots) that penetrate deep into the host’s vascular system, allowing them to regenerate from internal tissues.
Everyone is their own big solar; decentralized solar
That's the direct result of car lobbying, it has changed the perception of a whole generation on how we should build cities
How often did you have to add more cardboard to yours?
Sorry, I thought it fit the theme quite clearly as it shows how a car centric infrastructure hurts us all, including animals. That huge parking lot could have been housing, or a park, or perhaps a big ass tub for them to swim in. (ps: I'm not saying they should be locked up in the first place, as the sea is right over there where they could roam freely though)
By holding a bag below them when they pee or pipetted from pooled urine on leaf litter
Urine from individually identified chimpanzees was collected opportunistically and non-invasively using a pipette from fresh and dry leaf litter. Chimpanzees predictably urinate just prior to leaving a fruit crop and can often be seen preparing to do so by climbing to a lower branch of a tree. Urination on the ground is often accompanied by defaecation, and in these cases, urine was pipetted from pools in the leaf litter opposite the faeces. Samples were only collected on dry days, since rainwater on understory leaves cannot be visually differentiated from urine. Urine may also be collected directly from underneath urinating chimpanzees by holding out a clean disposable plastic bag placed over the end of a forked branch; urine samples collected from leaf litter were previously shown not to significantly affect measured hormone levels relative to samples collected using a plastic bag
They should make rain gardens in front of fire hydrants instead of leaving the space open for parking
