Tá Greta je strašná <>, prečo v Lidli nekúpi zváračku a nejde tie lodičky fixnúť?
uzitocna hlupana s jej agendou.
ked sa novinar pytal, preco nechodi strajkovat aj do ciny ci russka (naj znecistovatelia), ostala velmi tichucko.
takze toto eko divadlo je pre tupcov zo zapadu, aby tlacili na destrukciu svojho premyslu.
a najma aby zapad bol uplne zavisly a vsetko bral z vychodu..
eko propaganda v nemecku dosiahla "uspech"
zrusili atomky, a tupci aby im to cela siet nedrbla pri vykyvoch "eko zdrojov" musia vykryvat palenim uhlia a plynu..

Poďme ich kretenov zachraňovať petíciou.
To ozaj???
Dobre chlapče, ver si svojim rozprávkam o "neutrálnej elektrine". Ja si radšej prečítam odborné články z fachu.
Tieto ceny v dopadových štúdiách Green Dealu samozrejme nenájdete.
The LFSCOE-100 (the same as the plain LFSCOE from before) is the LFSCOE assuming that 100% of the power are generated via the selected technologies. This is generally an extremely unrealistic scenario. An example of a more common goal for a renewable grid is an annual average of 90% VRE and 10% biomass/gas power as a dispatchable backup.
The LFSCOE-95 therefore calculates the LFSCOE under the relaxed assumption that only 95% of the annual average is provided by the main power source, and 5% are from such dispatchable sources. As you can see, this has a dramatic impact on the LFSCOE of renewables: They decrease by over 50%. In the calculations for Texas, it yields practically identical LFSCOE as nuclear (97 vs 96 $/MWh)!
In conclusion, the most commonly cited figures from the LFSCOE paper are NOT the really important ones. They are highly artificial scenarios that drive up the marginal costs all the way up an exponential curve by using absolutely no dispatchable power plants at all, and relying purely on battery. Even a modest percentage of dispatchable power dramatically changes this.
It should be noted that LFSCOE are not perfect either. From my understanding, they do not account for every aspect of system costs, although they should get the bulk of it. But LFSCOE calculated under more realistic assumptions already greatly close the gap that many people appear to assume. So the idea that a primarily renewable strategy is impossibly expensive due to systems costs does not seem maintainable based on this paper, even before accounting for the continued price decreases as manufacturing capacities expand and new technologies are integrated regularly.
chcem na chatu zložiť baterku, objednal som 4 články od EVE 300Ah, 4s teda spolu na 12V( Taký mám rozvod, už to nezmením). Riešim teraz BMS. Neviete mi nejaký odporučiť? Stavia tu niekto baterky? Stačí mi na prúd 100A
Zatiaľ sa mi najviac pozdáva JKBMS JK-B2A8S20P

Chlapče, radšej sa pozri na realitu a cenu elektriny v Nemecku a Kalifornii, kde majú vietor a slnko podiel cez 40 % na výrobe elektriny. Hlavne, že vraj náklady na výrobu z vetra a slnka a cena úložísk klesajú.
Potom nemusíš zdieľať podobné názory a nebyť za primitíva.
Aktualna cena pre koncoveho domaceho zakaznika 20-23c/kWh (najlacnejsich 10 pri 3000kWh/rok)

A cena elektriny bude pekne rásť ako je potreba investovať do infraštruktúry.

Tak sem budem aj aj dávať vybrané dni, keď je cena elektriny v Nemecku nad 500 €/MWh?
Podniky vyrábajú nepretržite a nie len keď fúka. A tak radšej odstavujú výrobu.

A čo sa týka domácností, v Nemecku, tak tie mali elektrinu z 50 % z vetra a slnka, ale aj najvyššie ceny v Európe.

Presne tak, ak podniky vyrabaju nepretrzite (ako sam uvadzas), tak ich zaujimaju najma peaky, urcite nie priemerna cena.
Tak sem nedávaj cenu za 1 deň, ale vysvetli prečo podniky v Nemecku odstavujú výrobu. Určite sú nadšené z občasných zdrojov, ktoré sú že vraj najlacnejšie na trhu.
Hlavne, že vo fosílnej Číne alebo USA sú 1/3 ceny elektriny.
Dost tam riesi prave ceny energii v Europe, sebestacnost a problem s neodstatocnym pokrytim vypadkov obnovitelnych zdrojov, co vedie ku casto vysokym spotovym cenam a nekonkurencieschopnosti Europy, co sa uz zacina prejajovat v priemysle.
Neide o to co bude technologicky mozne o 15-20 rokov, dopad to ma uz teraz.
Co si o tom myslite?
Nie som expert no jeho analyzy mi pridu ze maju racio.
A pri troche šťastia zažije i vplyv špičky.
Precerpávačka je veľká stavba, za návštevu stoja i také Dlouhé stráne, no keď vidím jak už 35 rokov dokončujeme rozostavanú diaľnicu?
Len sa všetci obávame, keď sa niečo začne stavať či sa to dostavia a koľko nás to výjde.
mnavak asi tak 👍
