I agree it works both ways. I just wanted to remind that electric transportation is a small part of the overall electricity consumption (0.02 Quads https://en.wikipedia.org/wiki/Quad_(unit) ), while industry & comm

Lots of energy is consumed by the industry and some industries do not sleep at night. Blast furnaces for instance need a huge amount of energy ( https://www.energy.gov/eere/amo/articles/itp-steel-energy-us...

Last month I was traveling in Sri Lanka, and seeing all the tuk tuks zipping around, using those sub-optimal combustion engines, I thought that it would be little revolution when one would start selling EV rickshaws. Those vehicles are lig

Car dealership in US are in their own league. Coming from Europe it is difficult to appreciate at first. But when you see headlines like: "Roma was purchased last month by Texas car dealership magnate Dan Friedkin, who is worth $4.1

Are we blaming Waymo now for letting one car driving through a busy street ? It does not warrant to set the car on fire.

Indeed it looks like a low hanging fruit.

Do we know where officially Waymo is on the SAE J3016 scale ? I used Waymo in San Francisco, and to my not-expert eye, it did perform very well already.

Maybe we should not use so much water (for agriculture) in a desert area at the first place. Feels like we are putting fixes on top of fixes. "A Saudi Arabian company grows alfalfa on farmland in Arizona and California and sends it ov

It might not be voluntary decided, but it is more a less happening. renewable is used more and more, and nuclear is getting more interest lately. Lots of countries are putting incentives to electrify their economy, which is a necessary fir

The global economy is addict to fossil fuel. So fossil fuel like any powerful drugs that is in limited supply (limited resource), it is threatening the global economy, if we continue to use it OR if we stop to use it. We need a withdraw pl

As of now, fossil fuel is crucial for national security. The whole economy runs on fossil fuel. But fossil fuel has 2 main drawbacks: 1. Contribute to global warming 2. It takes millions of years to produce, and few days to consume (aka li

"no one wants nuclear" is not exactly the conclusion of the last COP. Several countries agreed to triple the electricity produced by nuclear. But you are correct, that some EU countries lost their source or natural gas (Nord strea

I agree this is armchair debate. The article is made by a business journalist on an Australian report, with a catchy title. It is a complex subject.

The question of the mix is interesting, and probably more complex than it looks as we might have to take the "electrification" of industries, transportation, heating, etc. over time into consideration. If EV become more popular, i

No one. We did not say that there is no wind at night, but it is possible to have no wind some nights. And since at night there is no sun, that is why the price of electricity would go up, if there were not nuclear (or gas/coal) to ru

Is comparing nuclear and renewable like apples and oranges ? One can run anytime, and the other depends on weather, time of day. If we only had renewable the price of electricity would go up at night, when there is no sun or wind. Unless t

As long as the piece is durable, it should be fine. I might be extreme, as I prefer fewer stuff of better quality, that last years. Like a pair of jeans that I can wear every day for years.

It might hit a wall, but it is supercharged right now. It does not look like a sustainable model for the planet for sure. Feels like they build items that are used few days, and then end up in landfill.

It would have been a 4D chess move for Microsoft to have instigated this, by making the board to make the first move. Allowing to break the status quo at OpenAI, and allowing to run the project at full speed.

Yes, but what about the same place, sitting on the tarmac in hot latitude airport (Singapore, Doha, Las Vegas, etc.) ? It is a bit puzzling to know that heat from lights could damage windows of an airplane.
