100 days to go !!!! 🏃‍♂️ With a group of 60 people, we'll attempt a record-breaking marathon, 1,120m below sea level in Boliden's Garpenberg mine in Sweden. This is done to raise money for 2 charities and change discussions around mining (critical for energy...) Consider donating

My family is against electric cars… Have been listening to all the usual misinformation arguments for 90 minutes and people wonder why I am quiet…

The doctor’s waiting room has some great reading 😎 @newscientist.com

A bit of a plug, but quite proud of that interview in @newscientist.com about the work we do at the Foundation. You'll also find how I deal with optimism/pessimism ;-) Thanks @tinymaddie.bsky.social for the great work www.newscientist.com/article/2482...

People often wonder how climate activists stay positive. I feel like I can get behind this method from @gregdt.bsky.social

In 2023, the world produced 4.5 billion tons of oil, 9 billion tons of coal, and 2.5 billion tons of fossil gas (lnkd.in/eUUxhqc5). The combustion of which released about 37 billion tons of CO2 into the atmosphere (lnkd.in/e5t6bdhR) www.circularity-gap.world

Red cap Proud to have contributed to the launch panel of the Make Science Great Again panel by @wedonthavetime.bsky.social Knowledge is power. Defending science is critical for well functioning societies

Great Sankey diagram about the global material flows of plastics in 2022. About 400 million tons produced. 98% of the feedstock were fossil- coal accounts for 44% and oil for 40% www.nature.com/articles/s43...

L’energie c’est simple et complexe J’ai eu le plaisir de discuter énergie avec Vinz Kanté sur sa chaîne Limit. On part des bases pour discuter de nombreux aspects de la decarbonation. Bonne écoute www.youtube.com/watch?v=Ts_g...

Il est sorti!!!! Une vision complete de la decarbonation des transports passant par l'énergie, l'aménagement des territoires, les politiques publiques et l'économie. Fier d'avoir pu contribuer a ce travail ! www.fnac.com/a21105661/Je...

Last year the share of low carbon electricity in the global mix reached 40% thanks for data deployment of renewables. But fossil production also increased albeit slower. Source ember-energy.org/latest-insig...

Energy security will become the highest priority for the transformation of the energy system- climate will come second at best. This graph shows how the US, EU, China fare on that metric. The US went from a major oil importer to a next exporter (it still imports a lot).

Geothermal is having a moment. Glad to support with QCF a study on the Future of Geothermal in the UK led by Project Innerspace. Listen to that episode of Cleaning Up to know more about what’s new in that field m.youtube.com/watch?v=n3I2...

Given that the energy transition seems to be entering a bumpy phase I have decided to get back to the basics and invest in a coal steam engine 😅

What is happening to the US science system is dramatic. De-funding science, taking references to climate change off federal websites etc, won’t change the reality of facts. And cutting your main innovation engine is just sabotage… www.scientificamerican.com/article/top-...

Fossil fuels represent 40% of the mass of global trade by sea (lnkd.in/ePs-G-pN). Some numbers for shipped fuels: - 1.3 billion tons of coal (lnkd.in/exipiBEx.) - 2 billion tons of oil (lnkd.in/eyW3EAXN) - around 550 million tons of LNG (lnkd.in/eKPmmmzR.) iea.blob.core.windows.net/assets/34511...

Time to impact Technologies can deploy fast. Recent examples are mobile phones, internet, vaccines, shale oil/gas, etc. But it can take decades between concept and commercialisation- as illustrated in the graph below for different energy-related technologies Source: www.iea.org/reports/net-...

Always a special moment when one receives the first hard copies!!! Release in France on April 11 !!

The EU has an electricity price problem- in large part because expensive gas sets the price of electricity most of the time. Customers currently do not get the benefits of installing low cost renewables…

Many countries are starting to see their oil demand be affected by the deployment of EVs. Below is the example of Norway where 96% of new cars sold are electric/hybrid. China oil demand seems to plateau too. This is how transitions start... www.bloomberg.com/news/newslet...

When will sodium ion batteries become economically competitive with Li batteries? A recent study looks at it in details by considering learning rates for both technologies- they see the 2030s as when it can happen depending on ambition and variations in the Li market.

Great article in the NY times about the deployment of renewables and how it is visible from space. The installed capacity of wind and PV is now over 1000 and 1400 GW, respectively www.nytimes.com/interactive/...

50 It is the number of metals one can find in a standard Seat Leon. In terms of mass, iron (for steel) accounts for about 80%, then follows aluminium (10%). One can find a few grams of gold and milligrams of things like indium All data here: www.sciencedirect.com/science/arti...

Countries in Africa have very different energy situations. Shown here is the Levelised Cost of Electricity, rate of electrification, the state of gas reserves (indicated if the country has over 5 tn cubic ft of reserves) and the share of electricity from fossil fuels. www.nature.com/articles/s41...

The use of coal is falling fast in the EU- it now accounts for less than 10% of electricity production. Interestingly, 2 countries (Germany and Poland) account for 75% of coal use for electricity production…

Has anybody tried to reboot 2025?? I think there has been a bug and we loaded the wrong version

Thanks again to everyone who joined our Climate Research Showcase! Watch our special lecture w/@joerirogelj.bsky.social, @gregdt.bsky.social, Larissa Kunstel-Tabet & Alyssa Gilbert, on: 📈 Current climate targets 🔋 The energy transition 🎓 Harnessing academia for climate innovation buff.ly/42CBWKp

While there has been progress in the last 10 years- we’re still on a path where current policies lead a level of warming of 2.5-2.9 degrees by the end of the century. And it is hard to imagine what a 2.9 degrees warmer world is…

Now our special lecture on the changing trends of climate research, with Professor @joerirogelj.bsky.social, Dr @gregdt.bsky.social, Larissa Kunstel-Tabet and Alyssa Gilbert @undaunted-hq.bsky.social, begins! 📺The lecture will also be recorded if you can't make it in-person!

It's on. So pleased that my TED is now online. The energy transition will be hard and messy, and will require to face a lot of tradeoffs and compromises. We should be prepared for that. www.ted.com/talks/greg_d...

📅Join us on tomorrow for our Climate Research Showcase! Sign-up to meet our research community, alongside a special lecture with @joerirogelj.bsky.social, @gregdt.bsky.social, Larissa Kunstel-Tabet & Alyssa Gilbert 🖱️https://buff.ly/4hiYhRq

2024 is the warmest year on record. But what is amazing is how 2023 and 2024 are off the chart compared to previous years berkeleyearth.org/global-tempe...

According to analysis from Copernicus just released, 2024 was the hottest year on record and the first to be 1.5 degrees warmer than pre industrial référence- note that global warming is taken as a 20-year average climate.copernicus.eu/copernicus-2...

Let’s not kid ourselves: Europe still buys a lot of Russian gas. Russian LNG accounted for 20 per cent of the EU’s overall imports in 2024. The only way to sustainably drive out Russian gas is to accelerate renewable energy buildout, electrification and energy efficiency.

Pretty impressive trajectory for the UK emissions from electricity production (In large part due to renewables…) Oh, and the grid is doing fine.

When in France, do like the French 😇 #snails #escargots

Lithium Battery prices have declined by 20% this year. Largest price drop since 2017. This drop is explained by cell manufacturing overcapacity, economies of scale, low metal and component prices, adoption of lower-cost lithium-iron-phosphate (LFP) batteries about.bnef.com/blog/lithium...

Coal use to reach a record this year (8.7 billion tons) and forecasts are for demand to go up until 2027 (knowing that last year the same forecasts were that peak use was for 2023…) www.bloomberg.com/opinion/arti...

The higher the GDP per capita of a country, the more its inhabitants travel for tourism. Tourism is estimated to have accounted for 9% of global emissions in 2019 (accounts for travel and activities) www.nature.com/articles/s41...

So: @CleaningUpPod has just racked up its half-millionth view. It's all about the guests. Don't miss this week's episode with @worthingtonbry.bsky.social and @gregdt.bsky.social: plasma physicist, Deputy CEO of Quadrature Climate Foundation and billion dollar man. www.youtube.com/watch?v=OsNd...

I had the chance to talk about climate philanthropy, fusion, the energy transition and climate tech in the CleaningUp podcast. Wide ranging and interesting discussion. And now you know what my job is 😅 www.cleaningup.live/how-climate-...

This week's episode of @CleaningUpPod is with @gregdt.bsky.social, Deputy CEO at Quadrature Climate Foundation. A plasma physicist by background, Greg has a beautifully nuanced view of how to address the climate problem - and $ billions in funding to distribute! www.cleaningup.live/how-climate-...

Where is oil extracted, traded and consumed each year? Here's a rather complex map that features data from the Energy Institute - Statistical Review of World Energy showing global consumption and production of oil in 2023. Oil still makes up a1/3 of world's primary energy mix.

Fossil fuel production is still not decreasing. Worse, it is increasing. The latest analysis from BloombergNEF (see graph below) shows that global production in 2023 was about 1.9% higher than in 2022. The US is the country which increased production (oil and gas) the most…

The food system as a whole represents more than a quarter of global emissions- see the image below. Livestock emissions (methane from cattle...), land use and crop production represent more than 80% of the total. Transport for example is a much smaller contributor than what one could initially think

I can live with that type of description. 🤩 The tool can be found here: blueskyroast.com/roast

in 2023 80% of new electricity demand was covered by renewables. This is short of what is needed (more than 100% if one wants to see emissions decrease) but has been steadily increasing- it was about 50% in 2015-17. Needs to be over 100% for emissions to go down speedandscale.com/wp-content/u...

The US is the second largest emitter but also the country whose exported emissions have increased the most over the last 10 years (raising questions about their overall climate impact). And there is no real discussions about decreasing fossil fuels production climateactiontracker.org/blog/highlig...

In 2024, total material extraction is estimated at 106.6 billion tons- a strong increase from 30 billions in 1970. per capita, the number increased from 8.4 to 13.2 tons/capita over the same timeframe. The most used materials are non-metallic (rocks, sand, etc) used for construction
