    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.

    The EU got 52% of its electricity from renewables in second quarter of 2024 | The Progress Playbook
    https://theprogressplaybook.com/2024/10/29/the-eu-got-52-of-its-electricity-from-renewables-in-second-quarter-of-2024/

    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.

    German energy market caps turbulent August with 68 hours of negative prices – pv magazine International
    https://www.pv-magazine.com/2024/09/04/german-energy-market-caps-turbulent-august-with-68-hours-of-negative-prices/

    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.

    SHEFIK: Aha:

    Prices for public charging or battery swapping are regulated, typically using the industrial electricity price plus a maximum service fee with time-of-use price differentials. Each province sets its own public charging price. Prices range from RMB 0.4/kWh to RMB 2/kWh, with RMB 1.5/kWh ($0.23/kWh) as a typical mid-price. Home charging in China generally employs the residential electricity price

    Renewables, grid flexibility could lead to electricity price drop of 25% by 2030 – pv magazine International
    https://www.pv-magazine.com/2024/06/25/renewables-and-grid-flexibility-could-lead-to-electricity-price-drop-of-25-by-2030/

    Modelling shows that electrification and flexibility can slash average day-ahead energy prices by 25% by 2030, and by 33% by 2040, compared to 2023. At the same time, the solar capture prices will be 71% greater in 2030 compared to the baseline, and 54% higher by 2040, supporting the sustainable growth of solar project developers, SolarPower Europe notes.

    Analysis shows large-scale PV still cheapest electricity tech in Australia – pv magazine International
    https://www.pv-magazine.com/2024/05/22/analysis-shows-large-scale-pv-still-cheapest-electricity-tech-in-australia/

    And for the first time, the report has included large-scale nuclear technology, which has been identified as the most expensive technology.
    ...
    The report shows firmed renewables, including transmission and storage costs, provide Australians with the cheapest power, at between AUD 83 ($55.25)/MWh and AUD 120/MWh in 2030. Were small modular nuclear reactors able to be up and running in Australia by 2030 the cost of their power would be up to AUD 382/MWh.

    To escape the trap, Vázquez needed rapid solutions. He turned to an unlikely source: Ramón Méndez Galain, a physicist who would transform the country’s energy grid into one of the cleanest in the world.

    Today, the country has almost phased out fossil fuels in electricity production. Depending on the weather, anything between 90% and 95% of its power comes from renewables. In some years, that number has crept as high as 98%.

    hehe, kdyz si tak vzpomenu na ty plamenny diskuzni vylevy par let nazpet, ze “max moznost oze v energetickem mixu bez blackoutu je 30procent”…

    “Renewable energies will have covered almost 52 percent of gross electricity consumption in 2023,” the organisations said in a press release. “This means that the share has risen by five percentage points compared to the same period last year and is above the 50 percent mark for the first time for a full year.” Germany’s renewables share was 46 percent in 2022. Both a decrease of overall electricity consumption and an increase in absolute renewables production – which rose six percent to an all-time high of 267 TWh - pushed up the share of renewable electricity.
