    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.

    Renewables are now cheaper than new coal power in India 🇮🇳

    New coal: ~USD 68/MWh
    Solar + storage: USD 33–41/MWh
    Firm and dispatchable RE: USD 49–67/MWh

    As renewables scale, India can meet its 2032 power needs without adding new coal.

    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.

    According to the Italian power transmission system operator (TSO) Terna, electricity consumption in Italy increased by 2.2% in 2024, surpassing 312 TWh, and renewable sources reached their highest share ever, covering 41% of power demand (compared to 37% in 2023)

    In 2024, the share of renewable energy in the Czech Republic's electricity generation was 15.9%. This is a relatively low share compared to the EU average of 46.9%.

    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.

    Renewables overtook coal

    A strong rise in solar, and to a lesser extent wind, led to renewables overtaking coal generation for the first time on record in the first half of 2025. Renewables grew by 363 TWh (+7.7%) to reach 5,072 TWh, while coal generation fell by 31 TWh to 4,896 TWh. As a result, renewables’ share of global electricity rose to 34.3% (from 32.7%), while coal’s share fell to 33.1% (from 34.2%).

    In the second quarter of 2025, 54.0% of net electricity generated in the EU came from renewable energy sources, an increase from the 52.7% registered in the same quarter of 2024. This increase was mostly due to solar energy, which generated a total of 122 317 gigawatt-hours (GWh) in the second quarter of 2025, representing 19.9% of the total electricity generation mix.

    June 2025 was the first month in history where solar energy (22.0%) was the main source of electricity generated in the EU, ahead of nuclear (21.6%), wind (15.8%), hydro (14.1%) and natural gas (13.8%).

    Among EU countries, in the second quarter of 2025, Denmark, with 94.7%, had the highest share of renewables in net electricity generated, followed by Latvia (93.4%), Austria (91.8%), Croatia (89.5%) and Portugal (85.6%). The lowest shares of renewables were recorded in Slovakia (19.9%), Malta (21.2%) and Czechia (22.1%).
