    PALEONTOLOG: Ovsem na rizeni gridu je treba uplne jinych modelu, nez tech generativnich. U generativni AI bych spis doufal, ze bude uzitecna pro vedu/progres jako takovy - ale k tomu je jeste kus. Zatim se LLM neda moc verit, dost bullshiti. Myslim si ale, ze tento problem budeme schopni resit (jde v zasade o to najit zpusob, jak kvantifikovat neurcitost nejakeho tvrzeni generovaneho LLM). Usetrime tim nejake CO2? To dost pochybuju. Spis se najdou zpusoby, jak pripadnou usporu offsetnout nejakym nesmyslem, treba inteligentnejsim tamagochi:-)

    ale zase buďme fér, není AI jako AI

    “Just like mining for Bitcoin, servers and processors are guzzling up energy with our everyday digital needs, but AI will 100% improve our transition to clean energy. By using algorithms to predict our energy usage patterns and forecast the availability of renewable energy, AI can efficiently manage the charge and discharge of batteries and perform load-shifting to optimise our energy use. The real question is, is the extra energy required for AI processing less than the energy it will save? Absolutely yes.”

    Is private capital the missing piece in $125 trillion energy-transition puzzle?
    https://pitchbook.com/news/articles/is-private-capital-the-missing-piece-in-125-trillion-energy-transition-puzzle

    The UK is almost a microcosm of a worldwide energy transition quandary—where the amount of investment needed, globally, is closer to $125 trillion. While each market faces its unique set of circumstances and advantages, the same structural trends and questions remain: Where do we get the money?

    That dilemma can be seen in two ways. First, there’s the question of how to fund new sources of renewable energy and build the accompanying storage infrastructure to support those new sources. Second, the world must modernize power grids to handle more demand stemming from things like the proliferation of electric vehicle charging networks and power-hungry data centers fueling digitalization and AI adoption.

    ...

    Private capital has already honed in on the world’s growing energy need, with several of the largest managers launching strategies targeting energy infrastructure. For example, KKR is currently in the market with a $7 billion fund targeting energy transition investments. As of April, Blackstone had raised $1 billion for its latest energy transition vehicle.

    While fundraising activity has dipped in the past year, infrastructure investors are sitting on about $334 billion of dry powder. PitchBook data shows that the total capital raised by infrastructure funds reached a peak in 2022 with about $138.5 billion raised across 122 globally. The previous year, 2021, saw a peak in the total number of fund closes, with 146 closing on $132.7 billion.

    ...

    Two of the largest fundraising hauls came at the end of the 2023, with Brookfield Asset Management gathering $28 billion for its fifth infrastructure fund in December. Around the same time, the United Arab Emirates announced $30 billion vehicle with the backing of BlackRock, TPG and Brookfield.

    ...

    “Society depends on a digital economy and it wants very clearly an economy where energy is abundant and cleaner, and this creates great investment opportunities,” he said. “The private capital sector is extremely well positioned to meet those demands and the government’s role is not to fund it, but to put the right playing field in place.”

    I když toho spoustu víme, přesně predikovat jak kde bude na nedovedeme.
    Pro Evropu může jít o změny v AMOC, pro Austrálii a Jižní Ameriku zase Jižní oscilace,..

    Pokud bychom toto nebrali v potaz, tak se Česko, nebo Skandinávie, jeví jako fajn místa.
    To samé se dá říct o Kanadě, a mně osobně se v této souvislosti dost zalíbila Jižní Amerika.
    Nicméně být kdekoliv cizincem je už dnes do nějaké míry nevýhoda a myslím, že bude ještě větší v době kdy lze očekávat více konfliktů, extrémního počasí, migrace,..

    Severní polokoule na tom není tak hrozně jako loni a Arktida se dokonce vrátila blíž k dlouhodobému průměru.

    YMLADRIS: nemas tu studii? bych se koukl.
    to je sle 3,3 globalni teploty ne? evropa se otepluje cca 2x vic (je bliz polu, kde je otepleni vyraznejsi, plus je to pevnina, ktera se otepluje rychleji nez ocean).

    btw plus to bude asi prumer modelu, ktery maj docela rozptyl, takze to muze v praxi znamenat jeste o stupen vic. zalezi, jaky budem mit stesti…

    ZAHRADKAR: naucila jsem decko anglicky a masivne ho socializuju (online) s detma ruzne po svete v nadeji ze treba jednou se mu bude hodit kamos ze Singapuru. nevim co se da delat dalsiho, kdyz je to bezprecedentni ... jako ze doufam ze bude schopen se spakovat a nekam vypadnout az jednoho dne pujde do tuhyho. ale chapu ze tou dobou uz muzou byt vyprodana obcanstvi. tak se snazim mu poskytnout vzdelani aby byl platnym migrantem jednou nekde, kde o nej budou stat...

    ZAHRADNIK s tim 4-6 stupnu otepleni teda nevim, dnes jsem zrovna koukala na novou studii z postupimi (Rockstrom) o tipping pointech a tam operuji worst scenario 3.3. samozrejme mozna se jim to jen dal nechtelo pocitat
