NEW PAPER: Why the 'Fabric First' dogma is out of date and needs a radical rethink. With our paper we want to provoke and start a discussion rather than provide all the answers. More in this 🧵 Paper with @ecioxford @UCL_Energy @NTUadbe in @BuildingsCities

"One of the best strategies [to move forward] is to lower the stakes." ~ Rick Rubin Very recognizable quote that explains some of the inaction that we sometimes observe.

Land-use (including mining) for various electricity generation technologies from @OurWorldInData: midpoints between 1 and 25 m2/MWh.yr Further benchmarks: * residential electricity use in EU: ~3.5 MWh/yr * in an all-electric home: ~10 MWh/yr https://t.co/AcU94P1ZJI

Are Electric Cars Sustainable? A nice review of a complex question, identifying the environmental hotspots for improvement, and how various BEV OEMs perform on them.

When it comes to sustainability in the automotive industry, low or zero-emission cars such as electric vehicles do make a difference in regards to reducing greenhouse-gas emissions. When looking at...

Green hydrogen for domestic heating!? It would need 4-5 more renewable electricity than a heat pump. How can this be ever justified? Excellent work from the University of Aberdeen’s Professor Tom Baxter @aberdeenuni

A few thoughts: * ESG claims need to be able to withstand scrutiny, but so do greenwash claims. * There are no inherently green products. * ESG is about alignment, data, disclosure, education, transparency, and it's a long-term effort.
While the intention of ESG investing should be applauded, investors are right to wonder: what is the ESG scam level? The question is: what really qualifies a stock for inclusion in an ESG fund? See @forbes

Good checklist for credible claims: 1) use standards or good practices 2) measure & bring data 3) verify by a third party 4) set a target & improve 5) define & expand scope https://t.co/qzCZtcxwpc

Speed is not very sustainable. At 40 Gb/s, this cable is fast and smart, but most the 40+ materials in its electronics at unlikely to be recoverable. https://t.co/kp719DvRio

Considering that an average car is driven 35 km per day, three to four hours of (Australian) sunshine suffice to keep this car unplugged. @dgcarvajal

Do solar-powered cars make sense? Here are a couple of numbers to help you make up your mind: * 5 sqm of solar panels * one hour of charging provides 12 km range (at 100 km/h) https://t.co/sz2hZGC5JB

How far do you need to drive an electric vehicle until it reduces carbon emissions compared to a petrol or diesel car? With the current electricity mix in Germany it is 40,000km. Great graphic by @martindopp @KITKarlsruhe.

Major new German hydrogen study by @oekoinstitut for @StiftungKlima. Key role seen in industry, electricity system balancing, aviation & shipping. Very limited role for hydrogen in transport and buildings. https://t.co/NGLNKUCrPE THREAD 1/6

By 2050, we will be hunting grams and kilograms of CO2, instead of today's tons.
@BengtHojer @thinkcopper @CC_Yale @GWECGlobalWind Thanks for raising the bar! I like this perspective 👍😀. Without fossil fuels, we are now talking about a difference between 2.5, 4 or 12 g CO2e/kg instead of today's 300 - 700 g. The @VattenfallGroup article covers the right angles.

"Electrify what can be electrified", says @TimmermansEU at the @Eurogas_Eu annual conference. I will talk about the options in heating later today. In short: #heatpump technologies are ready for all applications. Today.

A decisive focussed industrial strategy provides much stronger signals than market fundamentalism, but in the end, the energy transition is about collaborative change. https://t.co/NoD0qbhoOI
