No, per capita electricity usage dropped slightly over the last 25 years, driven in part by LED adoption.

Jevon's Paradox says nothing about the size of the incremental demand though. Lighting is a great example. The US went from spending 15% of our electricity on lighting to ~4%. LEDs are maybe 5x as efficient, so that would be 3% without

It will likely be on the enterprise side if it happens. Hard to control supply, but if demand is concentrated to a few hundred entities, that's easy to do.

Both can be true simultaneously. American companies were comfortable with a high cost structure because it padded their revenue numbers. The government tried to block out competitors through import/export controls, and it ended up back

Very nice work. Training these from scratch is a big undertaking. - Did you train the encoder & decoder together or separately? It would be nice to have the encoder representation be compatible with the existing whisper implementation s

EPA range tends to be pessimistic for EVs as it assumes you are always traveling at highway speeds. Even small reductions in speeds can make EVs much more efficient since drag is quadratic. A quick google search shows Prius prime owners rep

You can buy stock in a solar "yieldco", which is exactly this. It holds the assets of solar farms and pays out the cashflows. There were a lot circa 2018, I believe Brookfield bought up a bunch, so there may be fewer options now.

It's a very simple change in a vanilla python implementation. The encoder is a set of attention blocks, and the length of the attention can be changed without changing the calculation at all. Here( https://github.com/ope

If you are hosting whisper yourself, you can do something slightly more elegant, but with the same effect. You can downsample/pool the context 2:1 (or potentially more) a few layers into the encoder. That allows you to do the equivalen

Most of this decline isn't driven by a change in current fertility rates, but instead by a persistent trend downward in number of reproductive-aged adults. That was locked in by the fertility rates 20-40 years ago. These things move in

Your measuring wall time, not CPU time. It may be that they are similar, but I'd suspect you aren't loading the worker nodes well. If the savings are from the reduced shuffles & serde, it's probably something you can meas

When you talk between remote machines, you have to translate to a format that can transmitted and distributed between machines(serialization). You then have to undo at the other end(deserialization). If what you are sending along is just a

The difference in throughput for local versus distributed orchestration would mainly come from serdes, networking, switching. Serdes can be substantial. Networking and switching has been aggressively offloaded from CPU through better hardwa

Longshoreman is not a typical blue collar job. You cannot just go out and become one today. It is a nepotistic profession where positions are passed within families and closely guarded from external competition. Go read The Box. It outlines

It seems like the program has some issues to iron out, but the general concept is really compelling. Being able to group both the supply and demand side of delivery systems could make it really efficient. When you increase driver productivi

Norway's vehicle fleet is now 25% EVs and their per capita electricity usage is the same it was a decade ago[1]. Oil infrastructure uses a ton of electricity, and California refines most of the oil it consumes because of its geography

This feels like a convenient excuse for cost cutting. Experienced people are expensive. If you need to make cuts, it's an easy place to start. Ironically, it's felt like US tech companies have been moving in the opposite direction

I think that's the real loss here. Rental vehicles are a big source of cheap used cars. Having a steady flow of EVs from there would have brought down used prices and made them more financially accessible. Shame we won't see that

They just laid off 6,000 people. Sounds more like it was an attempt to get people to quit so they don't have to pay as much severance. https://www.firstpost.com/tech/tech-layoffs-2024-dell-fires-...

The article you linked is from 2017. 80% of Australia's solar was installed after that came out. Hard to argue that it's somehow responsible. Seems like your knowledge is a bit outdated.
21.
by conjecTech 2y ago
Australia is transitioning >3% of their electricity supply to solar per year and still accelerating. Rooftop solar is near 50% uptake. Combined with wind, they are on track to almost fully in the next 10 years. So there will be soon.

The grid was much nearer to collapse seven years ago when there were actually brownouts, and renewables have been entirely responsible for its improvement. Moving toward renewables and keeping the lights on in Australia are the same thing.

You make it sound like they have no alternative. A literal majority of the city uses the trains regularly. The person you're describing can just live within walking distance of a station. The $20k they arent paying for the car and toll

I do not think we should plan the city around the needs of doctors living in Westchester.

Smelting recycled aluminum uses only about 3% of the energy as creating it from raw ore. So yes, recycling allows us to do that more efficiently.

I worked at Reddit in the not so distant past. The entire recommendation system lived in 3 repos. I'm pretty sure there are just 2000 repos because the onboarding tutorials have you create one, and that number is probably around the nu

There is a good Volts[1] episode[2] on it. TL;DR the thing that limits how much power a line can carry is heat dissipation, which depends on weather. We used simple heuristic models to back out what we considered safe operating currents his

Noone wants to cut during the holidays. I'm guessing most of these were decided months ago. You're just seeing them happen as people get back into the office.

The benefit of building it into an appliance is that the device itself is certified, and you don't need an electrical inspection for just plugging it in. They mentioned adding a built-in outlet so that you could then have something els
