1/ New research @lut.fi @kit.edu @uahes.bsky.social presents new insights on the cost projections of sodium-ion & lithium-ion batteries & impact on the global energy transition doi.org/10.1016/j.es.... A novel bottom-up cost projection is combined with global energy-industry transition modelling.

12/ The six most used energy system models are HOMER, EnergyPLAN, LUT-ESTM, Balmorel, PyPSA, and TIMES. Thereof the by far most citations receive EnergyPLAN, HOMER, and LUT-ESTM.

1/ New research @lut.fi reviews the #100RE systems literature doi.org/10.1016/j.rs... for the full range of technologies and trends for a sustainable energy transition based on 1067 articles from 1975 to 2023.

So long, coal

1/ New research @lut.fi presents the first global analysis of inter-annual storage for #100RE systems in 145 regions doi.org/10.1016/j.ap.... Strategic generation overcapacity is a significantly more cost-effective solution than building massive storage.

NEW | Surging wind and solar power helped make electricity in Spain CHEAPER than in most European countries.

📈 As wind and solar grows…
📉 …The influence of costly fossil fuels on the electricity price shrinks

Climate tech is moving from “nice to have” to “smart capital allocation.”

BCG found:

55% of low‑carbon tech is already cost‑competitive (or soon), + another 10% is only marginally pricier.

Companies pursuing green growth (2016–2024) earned higher revenue valuations.

1/ New @lut.fi study in collaboration with European partners finds prioritising nuclear power expansion over renewable energy (RE) leads to 71–84% higher annual system costs in Finland by 2050 compared to a cost-optimised RE system. doi.org/10.1016/j.en...

Just look at what happened with solar investment - it’s astonishing.

Solar has seen the most rapid investment growth, soaring from $142 billion in 2015 to a projected $441 billion this year.

NEW ANALYSIS: A potential game changer for global emissions: China is on track for fall in emissions in 2025.

Clean-energy growth helped China’s carbon emissions fall by 1% year-on-year in H1 2025.

4/ We simulated the hourly offshore wind power production globally in 0.25° resolution using the ERA5 wind speed data, with the power curves of a contemporary Siemens turbine and a new GE turbine on the Haliade-X platform for future assessments.

3/ The capex of offshore wind is coming down and it is expected to decline precipitously over the coming decades, esp. floating foundations. Energy system modellers & energy policymakers need an assessment of offshore wind in the future.

Trumponomics 2.0 will erode the foundations of America’s prosperity The Big Beautiful Bill is symptomatic of a wider malaise

The Big Beautiful Bill’s neglect of the long term is part of a wider malaise in American politics.

It illustrates the long-term damage Donald Trump is doing to the foundations of the economy

The flood of German transshipments to Russia continues unabated. It's been over three years of this now and this stuff is just deeply shameful. The new government needs to make a decisive break from the past and shut these transshipments down. Not tomorrow. Not next week. Today. No more excuses...

🇲🇽 To reach 45% renewable power by 2030, #Mexico needs to TRIPLE renewable generation in FIVE years 📈

Such a rate of increase is fully ACHIEVABLE – examples from Latin American peers and Mexico itself prove this is possible ✅

Critics Slam Cost of Ontario SMR Plan, Question Dependence on U.S. Uranium Critics are taking a hard line on Ontario’s announcement that it will build four 300-megawatt small modular nuclear reactors (SMRs) at the existing Darlington nuclear plant near Bowmanville, with most...

Unsubsidized costs per megawatt-hour in 2030:
$33 to $51 for onshore #wind; $54 for utility-scale #solar; $105 to $113 for offshore wind; $214 to $319 for different SMR designs; $279 to $307 for conventional #nuclear plants.

China added 278 GW of solar and nearly 80 GW of wind in 2024.

Clean power met >80% of new demand.

As coal is now on track to peak before 2030, what should China do next? 🧵

Negative prices are opportunity for demand response.

Ukraine ‘one step away from nuclear meltdown’ Interview: German Galushchenko on why Russian missiles are putting the whole world in peril

Ukraine has been left “one step away” from catastrophic nuclear meltdowns because of Russian bombardments of its atomic power stations, the nation’s energy minister has warned.

The EU has a target to maintain land use, land-use change, and forestry (LULUCF) at -310MtCO2/yr by 2030.

Currently, LULUCF is moving in the wrong direction, due to climate impacts and increased harvest.

NEW DATA: 46.9% of EU electricity in 2024 came from renewables says @eu-eurostat.extwitter.link

🏆 Top performers:
🇩🇰 Denmark – 88.4% (mostly wind)
🇵🇹 Portugal – 87.5% (wind + hydro)
🇭🇷 Croatia – 73.7% (mostly hydro)

⬇ Lowest shares:
🇱🇺 Luxembourg – 5.1%
🇲🇹 Malta – 15.1%
🇨🇿 Czechia – 15.9%

40% of global shipping moves fossil fuels ⛽🚢

Double trouble:

1. Profits from hauling coal, oil and fossil gas 🛢️🔥

2. Ships run on bunker fuel—the sludge of oil refining 🏭

No security without energy security!
