No, AI Queries & Images Aren’t Carbon Bombs, So Stop Hyperventilating

Regular readers will either appreciate or hate that for roughly 20 months I’ve been decorating my articles and presentations with images generated by artificial intelligence algorithms. I’m not going to address the full range of reasons, but will just do some basic math on the electricity use to get a … [continued]

Decarbonizing Cement & Concrete Is Noble, But Why Will Developers Pay For It?

During what has become concrete month, I’ve explored the full range of actual and purported solutions to the climate problem that is the cement, steel, and concrete used in construction. The industry’s emissions are high, with every ton of reinforced concrete having a carbon debt of 0.3-0.4 tons of carbon … [continued]

Steel Reinforcement Is The Invisible Miracle Of Concrete Construction, But Comes With A Carbon Price

Reinforced concrete was invented in the mid-19th century, a game-changer in the construction world. French gardener Joseph Monier is often credited with its creation. While experimenting with materials to build stronger garden pots and tubs, he had the idea to combine concrete with iron mesh in 1849. Monier patented his … [continued]

Gravity Storage 101, Or Why Pumped Hydro Is The Only Remotely Real Gravity Storage

In my recent article celebrating the great month that pumped hydro had, between the Loch Ness Red John facility selling to Statkraft, the UK finally settling on cap and floor for the technology and China having 365 GW of power and 4 to 8 TWh of energy storage under construction, … [continued]

Concrete Is A Geography, Minerals, & Waste Game Played With Billions Of Tons Of Chips

As cement day turns into concrete week turns into concrete month, it’s worth considering how the absurd tonnages of concrete manufactured changes, often radically, depending on where specifically in the world the concrete is needed. That’s all because those absurd tonnages means that we move the stuff that goes into … [continued]

Publishing On Cement Decarbonization Brings Challenges, Corrections, & More Approaches

A few days ago I went deep on cement again, using an assessment of the processes of American clean cement startups to define the scope and magnitude of the problem, the chemistry and energy requirements of cement, why fixing it is critically important, and incidentally evaluate a couple of companies’ … [continued]
