“Humans aren’t very efficient movers—until you put us on a bicycle, when we become some of the most energy-efficient land travelers in the animal kingdom.”
The most efficient travellers are us on bikes.

Housing the homeless. Not sheltering the homeless & certainly not forcibly relocating them.
Construct low cost, energy efficient housing, near reliable resources, not in some food desert. Additionally, prodvide the housed with trained medical assistance & counselors. Not the cops. Never the cops.

1) PBS becomes a free prestige streaming network like HBO or Apple.
2) Each state gets its own federally funded newspaper (and the government cannot control the contents). Stipend determined by population.

🚨 BLADES ON THE MOVE 🚨
At one of our Octopus Energy Generation sites in rural France, we’re “repowering” old turbines by replacing them with more efficient, modern and bigger turbines. And huge blades = HUGE LOGISTICS to get these bad boys up and running.

This summer I’ll have adequate cooling (I do need to get a pedestal fan to blow the cool air into the bedroom) all my neighbours were given cooling too, but I’m also very aware so many people in poverty don’t have access to safe secure energy efficient housing. Climate change means more extreme

Yes, creating one with opt in policies for contributors to training data, that is energy efficient, and open source, and credits where it is getting information from reliably. I would be OK with that existing for things like maths literature search.
Very interested in doing anything I can to make AI work for mathematicians in the way that THEY need it to work, though very unclear on how to do this. It's a moral/ethical minefield, but we're in it, and I want to help.

This is a very important point. Immutable thermodynamic laws mean that burning stuff to make heat energy and then turn that into something useful is unavoidably inefficient.
But an electric motor can be 97% efficient...

“We don’t need to replace waste,” as I told the FT today.
Electrifying doesn’t just change the fuel, it shrinks the amount of energy you need.
Our forthcoming paper finds the same useful energy with roughly half the primary energy.
I call it Electrofficiency.

as much as I reskeeted most of this thread, I want to emphasize: even if the power consumption & GHG emissions of one query are as trivial as this article wants you to believe, training the models to respond to those queries is *extremely* energy intensive

The Democrats from Carter to Biden gave us a path forward. Carbon-free and fuel-free energy generation. Transmission, distribution and storage has become safer and more efficient. We could replace a car culture with a safer better car culture. With each car as a storage device.

This is what really gets me. I design building HVAC systems for a living (though I've never done a data center), I personally work hard to design buildings with nice efficient conditioning... only for the AI craze to come along and undo all our work, gobble up energy and not even do anything useful.
