    VSOUKOLOHLOREnergetika a energie v politické a hospodářské perspektivě
    Vše o politickém a ekonomickém dění v energetickém sektoru. Klub usiluje o to diskutovat téma energetiky v širších, nikoliv jen úzce technologicky a vědecky zaměřených (jakkoliv ani ty nejsou zakázány), souvislostech. Témata a kauzy typu: energetická bezpečnost, státní energetická koncepce a surovinová politika ČR, ČEZ, MUS, OKD, Bakala, Komárek, Tykač, Gazprom, územní limity, německý odstup od jádra, kanadské roponosné písky, rizikový managment, negativní externality energetických zdrojů, ropné havárie, válečné konflikty ohrožující dodávky energie, vliv spekulantů na cenu surovin apod.

    "When Ivanpah opened in 2014, it was hailed as a breakthrough for clean energy. Using nearly **350,000 mirrors** to reflect sunlight onto boilers atop towering structures, the plant generated electricity by heating water into steam 6. But advancements in photovoltaic (PV) solar technology—like rooftop panels—have made Ivanpah’s approach obsolete."

    “If I do the maths, from 0.5 per cent to 5 per cent [of global power] takes about the same time as from 5 per cent to 80 per cent,” he explained.

    “So that’s the point. You don’t notice it until it gets to 5 per cent and then from 5 to 80 is actually quite quick.”

    At current rates, solar is on track to provide 12 per cent of global electricity in three years, 24 per cent in six years, and 48 per cent in less than a decade.

    The Cost of Power Outages

    Among the main causes of these power outages is an aging electricity grid that hasn’t kept up with a changing climate and evolving demands from utility customers. Energy economists are still trying to calculate the full business impact of these outages. One Stanford professor calculated that a single blackout, on October 7, 2019, likely cost small commercial and industrial businesses $2.4 billion. To further understand the scale, consider that the Department of Energy estimates yearly power outages cost the U.S. economy $150 billion annually.

    PES: ok, tak kalifornie neni asi nejlepsi priklad stability, pac tam radi neviditelna ruka trhu bez reguli :) na druhou stranu i pres tyhle blackouty maji HDP srovnani s Nemeckem a pristi rok Nemecko nejspis i prerostou.

    Popravde, radsi bych zil v Kalifornii...

    It is the largest sub-national economy in the world. If California were a nation it would rank in terms of nominal GDP as the world's fourth largest economy, behind Germany and ahead of Japan (4.070 trillion).

    Renewables z dubna 2024:

    EXCEEDING DEMAND WITH 100% CLEAN ELECTRICITY: During 31 of the past 43 days, clean energy exceeded grid demand consumed at a point during the day; that's compared to only seven days all of last year. And, it was only two years ago in May that California first even momentarily met demand with 100% clean energy.

    In 2022, the average residential electricity price was $0.1504 per kilowatt-hour (kWh), while the average industrial electricity price was $0.0832 per kWh. In May 2024, the industrial electricity price was $0.0795 per kWh.

    Germany
    Industrial electricity prices including electricity tax reached 16.65 cents per kilowatt-hour in Germany, as of July 2024. Households in Germany on average paid 40.07 cents per kilowatt hour (kWh) in the second half of 2022,

    The EU got 52% of its electricity from renewables in second quarter of 2024 | The Progress Playbook

    Nuclear generation was up slightly and comprised 24% of the mix, meaning clean sources made up 76% of the region’s total electrical output.

    Offshore wind output surged 37% year on year, hydropower generation grew 21%, solar was up 20%, and onshore wind 6%. On the other hand, coal-fired generation fell 7% and gas output dropped 24%

    Čili přes léto chybí jen 24% a máme čistou elektřinu.

    BUMBAR: to je nakej divnej zdroj. V textu si protireci. A neni jasny, jestli zapocitavaj dotace, nebo ne.

    Not far behind Denmark, Germany has the second-highest electricity cost in the world according to most sources. On average, Germans pay approximately 53 cents (USD) per kilowatt-hour for electricity. As in Denmark, about half of Germany's per-kilowatt-hour rate can be attributed to high taxes on electricity production.

    trochu jsem si pročetl o čem je ten humbuk s jádrem a Googlem
    Amazon and Google have plans for fueling their data centers: Nuclear power - CBS News
    https://www.cbsnews.com/news/amazon-nuclear-reactor-investment-google-kairos-power/
    With Kairos, Google said it expects to bring the first small modular reactor online by 2030, with more to come through 2035. The deal is projected to bring 500 megawatts of power to the grid. For context, Google consumed more than 24 terawatt hours of electricity last year
    Amazon:
    Combined, the three announcements could account for more than 5,000 megawatts of power by the late 2030s with the possibility of more. All of that is still likely only a small fraction of the company's total energy consumption, a figure that Amazon does not report publicly.

    Three Mile Island nuclear plant to reopen, sell power to Microsoft - CBS News
    https://www.cbsnews.com/news/three-mile-island-microsoft-nuclear-power/
    The firm announced the 20-year deal would involve the restart of the Unit 1 reactor, "which operated at industry-leading levels of safety and reliability for decades before being shut down for economic reasons exactly five years ago today."

    Microsoft will buy energy from the plant as part of its goal to help match the power its data centers use with carbon-free technology, according to a news release announcing the deal. The reactor is expected to be online in 2028, pending approval from the U.S. Nuclear Regulatory Commission.

    Rabot Charge noted that 57% of grid electricity came from renewable sources in August, slightly below the annual average of 62%. This reduction in renewable energy share contributed to the higher average electricity price in August compared to July.
