    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.

    Financial times

    Spain's renewables build-out has structurally decoupled its electricity prices from gas markets.

    Gas now sets the price in only 15% of hours, compared to 90% in Italy.

    Countries that invested early in clean power are far less exposed to fossil fuel price shocks.

    Still think renewables can't power a modern economy? Portugal just hit 80.7% renewable electricity for the entire month of January. In the middle of winter

    2017: 41.8% ("ceiling" skeptics said we couldn't break)
    2023: 61.0% (Coal plants? GONE. Last one closed 2021)
    2026: 80.7% (new record, #2 in Europe: Only Norway is ahead because they’re basically one giant battery)

    They told us the grid would collapse. It didn't. They told us the 2025 blackout was the "end of renewables". Wrong again

    Portugal saved €703m in gas costs in a single month while the fossil fuel dinosaurs are still crying about "baseload". The transition isn't just happening; it’s accelerating

    USA 2025, Final EIA-860 is out, and 2025 really did it: 54 GW of new U.S. electric capacity, 96% clean. Solar again carries the offense, and we built more storage in 2025 than the cumulative total through 2023. More and more and more additions... but also record low retirements.

    --

    This is incredible. Like the previous few years, near all of the electricity capacity added to the grid was clean energy. The Inflation Reduction Act helped this - it made solar & wind cheaper but it also for the first time had a standalone incentive for grid storage. Look at the growth in storage!

    Accelerating energy transition towards renewables is central to net-zero
    emissions. However, building a global power system dominated by solar and
    wind energy presents immense challenges. Here, we demonstrate the poten-
    tial of a globally interconnected solar-wind system to meet future electricity
    demands. We estimate that such a system could generate ~3.1 times the pro-
    jected 2050 global electricity demand. By optimizing solar-wind deployment,
    storage capacity, and trans-regional transmission, the solar-wind penetration
    could be achieved using only 29.4% of the highest potential, with a 15.6%
    reduction in initial investment compared to a strategy without interconnec-
    tion. Global interconnection improves energy efficiency, mitigates the varia-
    bility of renewable energy, promotes energy availability, and eases the
    economic burden of decarbonization. Importantly, this interconnected system
    shows remarkable resilience to climate extremes, generation outages, trans-
    mission disruptions, and geopolitical conflicts. Our findings underscore the
    potential of global interconnection in enabling high renewable penetration
    and guiding sustainable energy transitions.

    Solar and wind growth meets all new electricity demand in the first three quarters of 2025 | Ember
    https://ember-energy.org/latest-updates/solar-and-wind-growth-meets-all-new-electricity-demand-in-the-first-three-quarters-of-2025/

    Solar and wind have grown fast enough to meet all new electricity demand in the first three quarters of 2025, according to a new analysis from energy think tank Ember. Ember forecasts that fossil power will not rise in 2025, marking the first year without fossil generation growth since the Covid-19 pandemic.

    The analysis shows that solar and wind are not just expanding, they are now growing faster than demand itself.

    In the first three quarters of 2025, solar generation rose by 498 TWh (+31%) and already surpassed the total solar output in all of 2024. Wind generation grew by 137 TWh (+7.6%). Together, they added 635 TWh, outpacing the rise in global electricity demand of 603 TWh (+2.7%).

    Solar energy is now the world’s cheapest source of power, says new study | Envirotec
    https://envirotecmagazine.com/2025/10/07/solar-energy-is-now-the-worlds-cheapest-source-of-power-says-new-study/

    Solar energy is now so cost-effective that, in the sunniest countries, it costs as little as £0.02 to produce one unit of power, making it cheaper than electricity generated from coal, gas or wind, according to a new study from the University of Surrey.

    Access to electricity stagnates, leaving globally 730 million in the dark – Analysis - IEA
    https://www.iea.org/commentaries/access-to-electricity-stagnates-leaving-globally-730-million-in-the-dark

    Early 2025 estimates suggest a modest acceleration, supported by record solar PV imports from China and new electrification policies in key countries.
    ...
    The expansion of electrification in rural areas – where affordability is often very limited – helps to explain this trend. In addition, the lack of infrastructure and the declining cost of solar panels and batteries have prompted many households to adopt solar home systems. These systems are typically smaller in size, restricting the amount of electricity that newly connected households can use.

    We often forget how far we have come: Today almost 3/4 of EU electricity generation is from non-fossil energy sources.

    It is not long ago that fossil fuels dominated the EU's electricity mix.

    This year their share is approaching 1/4 of EU electricity generation.

    Abu Dhabi is building the world's largest battery storage facility with a capacity of 19 GWh.

    The project by Masdar and the Emirates Water and Electricity Company (EWEC) is the world's first large-scale 24/7 renewable energy project in the gigawatt range. It combines a 5.2 GW solar park with a 19 GWh battery storage facility (19,000 MWh) and demonstrates that a continuous supply of renewable energy around the clock is possible. The project is intended to serve as a blueprint for other countries.

    china building a lot of nuclear is complete nonsense nukebro fiction

    Electricity Data Explorer | Ember
    https://ember-energy.org/data/electricity-data-explorer/?entity=China&tab=change&chart=change_by_source

    It's 3% of new generation over the past 5 years and decreasing share over the long term with renewables being 50% over the past 5 years and 98% of new generation this year (likely over 100% for the year as a whole meaning it's eating into coal's share).

    They've added more wind and solar in the last 12 months (in generation terms not just capacity) than their entire nuclear fleet. Next year they'll add more than their entire historic construction and the entire planned nuclear construction pipeline (plans which are consistently optimistic).

    Or to put it another way, the december solar output is now increasing by more each year than the all-time peak monthly output of their whole nuclear nuclear fleet which took 30 years to build. The August wind output (when wind is at its lowest) has increased by more than the peak output of the whole nuclear fleet in the last 7 years.

    They've also consistently failed to meet nuclear construction targets (by as much as 70%) whilst consistently hitting 200-300% of their renewable targets.
