SHEFIK: Tak nejen v Australii. Starsi clanek...

According to data compiled by the U.S. Energy Information Administration, there are seven countries already at, or very, near 100 percent renewable power: Iceland (100 percent), Paraguay (100), Costa Rica (99), Norway (98.5), Austria (80), Brazil (75), and Denmark (69.4).

The main renewables in these countries are hydropower, wind, geothermal, and solar.

A new international study, which debunks many myths about renewable energy, notes that many large population regions are “at or above 100%” including Germany’s Mecklenburg-Vorpommern and Schleswig-Hostein regions, New Zealand’s South Island, and Denmark’s Samsø island. In Canada, both Quebec and British Columbia are at nearly 100 percent renewable power.

MAKROUSEK: Ja chapu, ze ses deset let psanim blabolu zivil, ale nemuzes uz si dat volno?

JIMIQ: Tak vono by stacilo, kdyby se solary daly na 340 tisic hektaru, kde je ted repka.

m2 solarni elektrany pri dokaze bezne vygenerovat 151kwh rocne. nevim teda jestli spravnej udaj, kdyztak me opravte.
To by znamenalo, pokud bysme sli jenom do repky, ktera se ted pouziva na biofuels a zbytek zemedelstvi nechali uplne bejt - tak to dava 516TWh rocne elektriny. To znamena 7x vic nez je rocni spotreba CR.

Takze ja myslim, ze Makrousek se muze vratit k psani pro McKinsey a my se o produkci potravin bat nemusime :]]

MAKROUSEK: tak to je samozrejmy, ze to nespadne z nebe. Pre-rekvizity potrebujes ke splneni jakyhokoliv planu a plan se o ne ma postarat. Ja jen nechapu co rozporujes. Ze nemuze jet svet na 100% renewable?

V australii uz tam skoro sou. Stejnej model sice nepujde pro CR, ale kdyz je to uz v reseni nekde, tak jinej model pujde jinde. Co presne je pro tebe nerealny, nebo not feasible a proc bysme meli/museli zustat u fosilu?

South Australia set to be first big grid to run on 100% renewables
https://www.climatechangenews.com/2022/09/16/south-australia-set-to-become-first-big-grid-to-run-on-100-renewables/

South Australia leads the world with the penetration of wind and solar in its grid, and has averaged more than 64% over the last 12 months.

It regularly reaches levels where wind and solar produce more than 100% of state demand – in fact it set a new record of 146% of state demand from wind only on Wednesday morning – but this excess is exported to Victoria through its transmission links.

MAKROUSEK: ano, to jsem si odvodil i ja z me zkusenosti s konzultantskymi firmami. Jen nerozumim tomu, proc rikas, ze to jsou blaboly.

Je to summary na urovni CR, ne jednotliveho odvetvi, podporeny zdroji ze kterych vychazely.

Nechces mi tvrdit, ze si McKinsey vymysleji nerealne veci, bez podkladu a feasibility overeni, aby ziskali business, ktery se neda realizovat? Takhle prece konzultantske firmy nepracuji a reputacni riziko takoveho rozsahu by si ani na sebe nevzali.

Btw. pokud si sam delal 10 let konzultanta, tak mi tvrzeni, ze skalovatelnost nejde podporena argumenty 'pod solarky nerostou rostliny' prijde dost kosata. Nezlob se, ale nejak v tvych tvrzenich nevidim moc realnych argumentu.

Jinak zaplnit cele Cesko panelama by pri 78 miliardach m ctvrecnich dalo 15,6 TWp vykonu :D (200W/m2)

Celosvetova spotreba veskere energie se odhaduje na 17TW (kontinualnich)

MAKROUSEK: jednak agrivoltaika dle ruznych zdroju funguje, urcite nebrani rostlinam rust, u nekterych plodin je castecny stin zadouci, plus prinasi benefity jako uspory vody v krajine.

A jednak tu mame eu energeticky trh. Nikdo nerika, ze musime byt v CR energeticky sobestacni a vetsina velkych energetickych firem na ceskem trhu neni lokalnich, ale regionalnich / globalnich.

Pak taky neni z fit for 55 ani vylouceny jadro, aby se cesi taky trochu nazrali a nefrfnali.

Abych neplkal, tady je treba temer 2 roky stary summary od McKinsey, kde uvadi, ze bez plynu bude bolet jen poslednich par procent, a to hlavne ve stavebnictvi, ne kvuli elektrine, nebo vytapeni.

Coz je uplne neco jinyho, nez 20ti lety flat kontrakt na plyn, nebo feeling z tveho nenaskalovatelneho prispevku.
