    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.

    You cannot make this up: Even Saudi Arabia is doubling down on solar power to meet the needs of the A.I. data centers it wants to recruit from the West, while Trump’s “big, beautiful bill” actually does just the opposite. It quickly phases out tax credits enjoyed by utility-scale solar and wind — as well as electric vehicle tax credits. This virtually guarantees that China will own the future of solar energy, wind power and electric cars and trucks, as well as autonomous vehicles.
    ...
    Consider this snapshot: In 2000 China produced just over 1,300 terawatt hours of electricity while the U.S. produced nearly 3,800 (a terawatt is equal to a million megawatts). Fast forward to today, China produces over 10,000 terawatt hours while the U.S., since 2000, has added only 500 — an increase of only 13 percent in two and a half decades. Much of China’s electricity growth originally came from expanded coal-fired generation, but in recent years it has been driven by expanding hydro, solar, wind and battery sources, which are easier, cheaper and quicker to build and also help the climate.
    ...
    Let’s say you want to generate additional electricity for more data centers just through natural gas today. Even if you have an abundance of gas, as America does, you need more giant turbines to convert the gas to electricity. If you ask the major manufacturers of those turbines — GE Vernova, Siemens Energy and Mitsubishi Power — they will likely tell you that they will be very happy to deliver you one, but you will be lucky to have it installed by 2030. That is how long their backlogs are. And there is no telling what that turbine will cost with all of Trump’s new steel and aluminum tariffs.

    By contrast, you can build and put online a new solar farm with battery storage in Texas in just 18 months.
    ...
    The result for Americans? The research firm Energy Innovation, whose peer-reviewed energy modeling is widely respected, projects that Trump’s effort to diminish America’s renewable energy industry will cause wholesale electric power prices to increase roughly 50 percent by 2035, and that cumulative annual consumer energy costs will increase more than $16 billion by 2030. It also projects that some 830,000 renewable energy jobs will be lost or not created by 2030.

    For all of these reasons, I am certain there are only two political parties in the world today cheering the passage of this bill: Trump’s Republican Party and the Chinese Communist Party — because nothing is more destined to make China great again than Trump’s “big, beautiful, America surrenders the future of electricity to Beijing” bill.

    Batteries are so cheap now, solar power doesn’t sleep | Electrek
    https://electrek.co/2025/06/20/batteries-are-so-cheap-now-solar-power-doesnt-sleep-ember/

    A new report from global energy think tank Ember says batteries have officially hit the price point that lets solar power deliver affordable electricity almost every hour of the year in the sunniest parts of the world.

    The study looked at hourly solar data from 12 cities and found that in sun-soaked places like Las Vegas, you could pair 6 gigawatts (GW) of solar panels with 17 gigawatt-hours (GWh) of batteries and get a steady 1 GW of power nearly 24/7. The cost? Just $104 per megawatt-hour (MWh) based on average global prices for solar and batteries in 2024. That’s a 22% drop in a year and cheaper than new coal ($118/MWh) and nuclear ($182/MWh) in many regions.

    Ember calls it “24/365 solar generation,” and it’s not just a theoretical model. Cities like Muscat, Oman, and Las Vegas can hit that steady power mark for up to 99% of the hours in a year. Hyderabad, Madrid, and Buenos Aires can reach 80–95% of the way there using that same solar-plus-storage setup with some cloud cover. And even cloudier cities like Birmingham in the UK can cover about 62% of hours annually.

    A record 32.4% jump in solar generation during January to April from the year before has helped utilities to lift overall electricity supplies while keeping coal-fired generation flat and cutting natural gas-fired output by 27%, Ember data shows.

    At 7:45 p.m. (PDT) on May 20, battery systems connected to the California Independent System Operator (CAISO) grid hit a new peak instantaneous electricity output of 10,030 MW, becoming the single largest source of electricity on the grid at that moment and the second-highest peak output of the day, behind solar power generation.

    Meta and Microsoft are working to fire up new nuclear power plants. OpenAI and President Donald Trump announced the Stargate initiative, which aims to spend $500 billion—more than the Apollo space program—to build as many as 10 data centers (each of which could require five gigawatts, more than the total power demand from the state of New Hampshire). Apple announced plans to spend $500 billion on manufacturing and data centers in the US over the next four years. Google expects to spend $75 billion on AI infrastructure alone in 2025.

    The carbon intensity of electricity used by data centers was 48% higher than the US average.

    China has hit a major renewables milestone, with wind and solar generating 26% of the country’s electricity in April.

    That’s the first month on record where the two technologies have together supplied more than a quarter of demand.

    The record-breaking month, revealed by global energy think tank Ember, beats the previous high of 23.7% set just weeks earlier in March.

    Solar output alone hit 96TWh – a new monthly record – while wind contributed 13.6% and solar 12.4% of total generation.

    In the first three months of 2025 alone, 72GW of new solar capacity was installed, up 18% on the same period last year.

    Britain hit by unusual power activity hours before Spain blackout
    https://www.yahoo.com/news/britain-grid-operator-investigates-unusual-105021635.html
    Britain’s electricity grid operator is investigating unexplained power plant failures that hit the UK’s system hours before Spain and Portugal were plunged into blackouts.
    ...
    The first event began at around 2am with a power failure at the Keadby 2 gas-fired power plant in Lincolnshire, followed by the unexplained failure of the Viking Link interconnector between the UK and Denmark.

    At around 6pm, the frequency shifted unexpectedly again – with the cause currently unknown.

    Less national control, more integration needed in EU's 'grim' energy market - Euractiv

    Failed electricity policy, not climate policy, is to blame for high energy prices - and European politicians need to get serious about working together to get them down, says energy researcher Conall Heussaff.

    The global power system will be dominated by two mega-trends over the rest of the decade:
    solar’s share in the electricity mix rising rapidly as it continues its exponential growth, and
    robust electricity demand growth as electricity replaces other forms of energy powering the
    global economy.
    Signs of this are already here: solar has been the largest source of new electricity for the last
    three years, and new drivers of demand such as EVs, heat pumps and data centres are
    contributing 0.7% to annual demand growth, more than twice as much as they did five years
    ago

    "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."
