immagini dal futuro

la vista dalla mia finestra in una bella giornata di inverno, il 31 dicembre 2020, un anno che se ne va, quanti anni dovranno andare e venire finchè non si vedrà più alcun pennacchio di riscaldamento contro il cielo di Milano?

Immaginiamo che tra 10 anni si successo, la domanda di energia dell’inverno boreale è l’ostacolo più arduo per il passaggio completo alle rinnovabili. Se lo effettuiamo, come sarà diversa la città? Solare uvunque, cambiano i tetti, ma anche tutte le facciate cambieranno, incappottate e ricoperte di pannelli. Nelle strade ci saranno solo auto elettriche, magari meno e in sharing, più marciapiedi e più locali, più vita all’aperto se l’energia ritorna abbondante come ai primi tempi del petrolio e si possono sperimentare nuovi modelli. io mi immagino sempre i nuovi giostrai cone maga camion di realtà virtuale, più potenza di calcolo di una datacenter di google oggi. un grande bocchettono per l’energia

un amico si immagina nel sottosuolo, sotto ogni palazzo, la serra aeroponica condominiale per molti piani all’ingiù, che sfama i condomini.

Per ora però in città sui tetti non so vedono pannelli solari se non sui palazzi più nuovi, sapete che è dovuto tutto a una legge? Se installi i pannelli su un condminio possono alimentare solo le parti condominiali, nei vecchi palazzi solo androne e scale, nei nuovi anche le caldaie elettriche per cui lì ci sono. Per vederli ovunque c’è da aspettare che la legge permetta le reti private ance per i clienti di consumo.

Cheap inputs and tech epochs

from Carlota Perez “Technological Revolutions and Financial Capital”Screenshot 2020-06-17 at 11.23.56

4th epoch is cheap oil, 5th is cheap bits. 6th?

If it has to be Green then it has to be renewables energies, cheap renewables?

cheap and abundant, the two things are tied in learning curves. Ramez Naam is working the Pareto curves himself.

Solar Future in Insanely Cheap

But a planet on renewables would require a lot of solar and wind, for example this report on reaching 90% renewables in the US calls for doubling new installation every year in the 20s and trebling in the thirtiesScreenshot 2020-06-17 at 11.55.17

Covid and global warming

“What Covid-19 teaches is that it is not just the big picture that matters. So tightly knit is our global system that small failures of governance in a few crucial nodes can affect everyone on the planet.”

“On the one hand are the huge medical risks; on the other is a disastrous economic crisis. How can we make the trade-off? It is tempting to reject the choice as impossible or false. Not only is that not true, it also denies the fact that, under normal circumstances, we routinely engage in life and death trade-offs. Even in the most affluent societies, financially motivated decisions are made every day that decide the chances of death due to workplace accidents, pollution, car crashes, hospital funding, drug procurement and health insurance.”

technologists for the environment

“without models, there are no data. I’m not talking about the difference between “raw” and “cooked” data. I mean this literally. Today, no collection of signals or observations—even from satellites, which can “see” the whole planet—becomes global in time and space without first passing through a series of data models.”

“Paul N. Edwards – A Vast Machine_ Computer Models, Climate Data, and the Politics of Global Warming”

” A reanalysis project involves reprocessing observational data spanning an extended historical period using a consistent modern analysis system, to produce a dataset that can be used for meteorological and climatological studies.”


Philosophers should talk more about climate change. Yes, philosophers.

“You have probably heard the common deniers’ complaint that climate scientists adapt models when new data comes in. That is supposedly unscientific because, here it comes (..) But the deniers’ argument merely demonstrates they know even less about scientific methodology than particle physicists. Revising a hypothesis when new data comes in is perfectly fine. In fact, it is what you expect good scientists to do.”


ESG – Evironment Social Governance

Acronym to remember

but WSJ reports that 8 of 10 have investemnts in things like Exxon Mobil, as sustainable as it gets fi you want, as Blackrock does, offer same risk and return that in the broad market.

Money is surely not where the mouth is, as some point the giration might be more violent than expected
