Tak to jsem zvedav:]

Vláda se po letech jednání rozhodla vyjít vstříc požadavkům energetické firmy ČEZ. Na nový jaderný blok jí poskytne garantované výkupní ceny. Ochrání ji tak před rizikem, že by elektřina v budoucnu byla příliš levná a reaktor se neměl jak zaplatit.

"Státem zřízená společnost bude odebírat veškerou produkci z nového jaderného bloku, a stát tak nad ní bude mít plnou kontrolu," popisuje způsob, jakým by měl nový reaktor prodávat elektřinu, mluvčí ČEZ Ladislav Kříž.

Tím, kdo ponese většinu rizik, nicméně bude stát, respektive daňoví poplatníci. V současné době stojí jedna megawatthodina mezi 40 a 50 eury. Za tyto ceny by se nový zdroj nikdy nezaplatil. A pokud tedy elektřina významně nepodraží, bude vláda ČEZ doplácet miliardami ročně.

Podle Míla ale levná elektřina kolem roku 2038, kdy se plánuje plné spuštění bloku, nehrozí. Vládní jaderný výbor má prý analýzy, podle kterých cena elektřiny poroste. Odůvodňuje to například plánovaným zavíráním uhelných elektráren a nedostatkem výkonu v evropské síti.

Podle Michala Šnobra, který zastupuje asi jedno procento minoritních akcionářů, je ale i současné nastavení pro ČEZ rizikové, protože se firma zaváže zároveň dostavět blok včas a podle dohodnutého rozpočtu. To ale nikdy jiný v Evropě nezvládá, prakticky všechny bloky, které se dnes v EU staví, bojují s násobným růstem nákladů a mnohaletým zpožděním.

Elektřina z nových reaktorů bude zřejmě příliš drahá, riziko má nést za ČEZ stát. Plán může narazit v Bruselu | Hospodářské noviny (iHNed.cz)

TUHO: zrovna vcera jsem zabredl do podobneho problemu a nasel co s tim delaj napr v USA nebo ve Francii. nejsem lesnik, stacilo par kliku na netu a dve odborne stranky:

Nokuse Plantation is a 53,000-acre private nature preserve located around 100 miles east of Pensacola, Florida. The preserve was established by M.C. Davis, a wealthy philanthropist who made his fortune buying and selling land and mineral rights, and who has spent $90 million purchasing land for the preserve, primarily from timber companies. One of its main goals is the restoration of longleaf pine forest, to which end he has had 8 million longleaf pine seedlings planted on the land.

A 2009 study by the National Wildlife Federation says that longleaf pine forests will be particularly well adapted to environmental changes caused by climate disruption.

As well as divesting its endowment from fossil fuel companies, the University has also asked its endowment office, Oxford University Endowment Management (OUem) to engage with fund managers to request evidence of net zero carbon business plans across their portfolios. There will also be a new member of the Investment Committee, with experience of both endowment management, but with an additional focus on climate-conscious investment.

Further cost reductions in both large scale solar PV and onshore wind projects mean that these two technologies are now the cheapest form of new build energy generation in areas that count for two thirds of the world’s population, and 85 per cent of the globe’s electricity generation.
The latest benchmark report from research company BloombergNEF show that in just the last six months the levellised cost of electricity (LCOE) for onshore wind has fallen a further nine per cent, its most significant drop in five year.

Great Britain has run for a new record of 18 days, six hours and 15 minutes without burning coal to generate electricity – and counting – as the coronavirus lockdown cuts demand by nearly 20%.
This combination means CO2 emissions from the country’s electricity system have been cut by a third during the coal-free stretch relative to the same period last year, Carbon Brief analysis shows.
During the record-breaking period, demand has been 18% lower than last year, as businesses around the country are closed due to the coronavirus response.
Renewables have been the largest source of electricity, supplying 37%, with another 32% from gas and 22% from nuclear. The remaining 9% has been imported from France, Belgium and the Netherlands.
The figures are in stark contrast to 2012 – the earliest available detailed data – when coal supplied some 43% of the total for Great Britain, another 26% was from gas and just 7% was from renewables.

Yet policymakers and investors have not fully absorbed the ramifications. The COVID-19 pandemic will probably keep demand very low for at least 18 months — the time needed to develop and roll out a vaccine — and most likely several years. That’s too long for the global oil industry as we know it to survive.
Prior to the pandemic, the oil industry was already on the brink. Although there is plenty of oil left, it is “increasingly expensive to access,” as the Geological Survey of Finland — a Finnish government agency overseeing the EU’s mineral resource modelling — noted in February. Since 2005, when production of conventional crude oil began to plateau, 71 percent of the growth in the global oil supply has come from US shale deposits, which are accessed by hydrofracturing, or fracking. Ramping up that production became so costly that most shale oil companies had negative cash flow. They compensated for it by drawing down debt that was rapidly becoming impossible to repay.

Myslím, že v situaci, kdy se mohou projektu účastnit média jako Al Jazeera, agentury jako Reuters nebo AFP, deníky jako Gazeta Wyborcza, Libération nebo El País, měla by být účast českých médií, která se pokládají za solidní, úplnou samozřejmostí. Klima patří k tématům, v nichž je česká debata zoufale zaostalá. A média, včetně těch lepších, za to nesou bohužel lví díl odpovědnosti,“ komentoval osamocenou účast Deníku Referendum šéfredaktor Jakub Patočka.

I am collecting materials for a post on effects of COVID-19 on renewables. This is one of the sources. The EU has seen a 20% drop in CO2 emissions and an increase in the power from renewables by 8% from 35% to 43% of the power generation across the whole of the EU + the UK (while Coal-based power generation has fallen by 25.5%). They didn't expect this to happen until the end of this decade. Of course it is not a permanent chnge, but it lets them test drive our power grids with a much higher mix of renewables and it is working fine.

The extreme oldness of this documentary stands out. In one instance, he tours a solar farm in Lansing, Michigan, in which a bemused official states that a large farm can only power ten homes in a year.
It is the Cedar Street Solar Array, a 150 kilowatt 824 (that’s small) panel farm in downtown Lansing. Guess when that bad boy was built? 2008. Twelve years ago – an absolute eternity, in solar development years.
As PV Magazine writes, “The film reports on a solar installation in Michigan with PV panels rated at “just under 8 percent” conversion efficiency. It’s difficult to identify the brand of panel in the film (Abound?) — but that efficiency is from another solar era”. Efficiency gains in solar have been so rapid that by leaving the dates off his footage he is very actively deceiving the audience. The site generates 64-64 MWh a year, according to the owner – a more recent installation in the same area generates around 436. The footage really is from another era. It’s like doing a documentary on the uselessness of mobile phones but only examining the Motorola Ultrasleek.
Later, they visit the Solar Energy Generating System (SEGS) solar farm, only to feign sadness and shock when they discover it’s been removed, leaving a dusty field of sand. In the desert. “Then Ozzie and I discovered that the giant solar arrays had been razed to the ground”, he moans. “It suddenly dawned on me what we were looking at. A solar dead zone”.
Which is a weird one, because the latest 2020 satellite imagery shows a site full of solar arrays, and a total absence of any “dead zones”. The damn thing is generating electricity.

"“I think the main issue is that people focus way, way too much on people’s personal footprints, and whether they fly or not, without really dealing with the structural things that really cause carbon dioxide levels to go up,” said Gavin Schmidt, a climatologist and the director of the NASA Goddard Institute for Space Studies in New York City."
