Thing is, coal is expensive. Solar is cheap. If the US goes all in on coal, oil, gas, etc. - she'll lose.

China has built out massive amount of solar and wind, and hunkering down on batteries. That means they get massive amounts of essentially free electricity.

If the US hunkers down on labour intensive, expensive, polluting stuff - then all the worse for her.

Comment I'm quite certain we've already solved this. (Score 4, Interesting) 165

First off: I'm not a climate change denier. Secondly: I do worry about the current US administration that seems to be entirely unhinged.

However, I think climate change is a solved problem, it's just the implementation that takes a bit of time. Thing is, solar panels have gotten dirt cheap. Battery prices are also plummeting. The cheapest electricity you can get at the moment is .. solar. It pays itself back within a relatively short time period. It's an upfront investment - but the return on investment is so massive that it just makes sense to build it out.

Which is why China has been doing exactly that for some years now. Which is why India is investing massively. Which is why Chile is building out in the Atacama desert. Which is why southern europe has built out quite a bit. Which is why Australia has built out massively. .. and which is why we're now seeing Africa importing quite massive amount of solar panels.

Of course, the objections about "what to do when the sun don't shine?" is entierly valid. The answer to that question, however, is batteries. Those prices are also plummeting. I expect to replace the batteries I bought in 2020 in about 2030 - and pay the same price for twice the capacity. They'll be cheaper in reality - due to inflation.

China is currently generating about 20% of their needs from wind+solar. We only need to go 5 years back for that to be less than 5%. In another 5 years, I'll be very surprised if they haven't reached 35-40%.

There's of course the problem of grid inertia. Grid-following is nowhere near as good as grid forming. We do, however, have the technology to fix that too. From flywheels to grid-forming inverters.

Give it 2-3 more years and "everyone" will see that it's solved. Give it 5-6 years and we'll be "on schedule". Give it 10 years and we'll all be surprised that we're ahead of schedule.

And we won't even need government incentives. It'll just be everyone doing what makes economic sense. Unless actively sabotaged through tariffs.

Oh gods no. Drip coffee beats americano any day of the week. Yech. I avoid americano like the plague.

We finally got a drip coffee machine in addition to the espresso machine at work. If I want espresso - I'll have that. If I want a nice "regular black coffee" - drip coffee any day.

Hi there; Norwegian here. Not an EV pimp, but rather a guy that bought a used Tesla Model S 2014 back in 2018.

In my "price range", I've never had a nicer car to drive. It's fast, it's fun. Charging has never been a problem for me, but I can imagine it being troublesome for folks who drive long distances often. I charge during the night. If I go on a lengthy trip, I just stop for a bit at superchargers. They're "everywhere" in Norway, so whenever I need a break - I just pop by the closest supercharger and go to the loo, walk around a bit, and 20 minutes later I keep driving.

Of course, a 20 minute break every time you want to refuel might sound extremely annoying to folks that drive long distances often enough that this causes several long breaks a day for them. For me, it means I have to take a break to recharge maybe 5 times a year. I don't drive long distances often enough to need anything but home charging.

That adds another advantage (for me) compared to gasoline cars. The number of times needed to refuel. I don't need to stop at the gas station to refill very often, as the regular 'refueling' (or recharging in my case) is simply done at home, during the night.

Comment Re:Solar is the future. (Score 1) 131

I think I see what happened here; With "people" I didn't think of individuals adding it as rooftop solar, although that's nice too. I meant people who make financial decisions for power plant buildouts. People who make financial decisions for where their business is going to get power, etc.

I'm mostly thinking of grid scale projects. Which are already happening in both Texas and Arizona in the US from what I gather from articles in The Economist.

I'm also thinking of places like the Atacama desert between Chile and Peru. Various areas of Mexico. South East Asia. The middle east. Northern Africa. Southern Africa (Namibia, South Africa, etc).

The Economist (www.economist.com) convinced me with their June 22nd 2024 issue ( https://www.economist.com/week... ). Specifically, see the article: https://www.economist.com/inte... among others in that issue.

Solar is cheap, abundant, and will come out on top due to economic reasons alone. No subidies required.

Batteries are also needed, of course, but they're also dropping in price as China ramps up production.

The entire thing will be a slam dunk. It'll be entirely obvious 5 years from now, but we're still in the phase where a lot of people haven't caught on and realized that this is the cheapest option.

Comment Re: Python is scripting, not a programming languag (Score 4, Insightful) 85

I'm not OP, but I can give you my answer to what you're asking:

A script mainly executes *external commands*.

Most languages can be used to write scripts. They can also be used as a "real" language. Some with more difficulty than others. Bash being an extreme example. You can do a heck of a lot in "pure bash" w/o relying on unix commands. Most people don't bother though. Thus, they write scripts.

When I started using perl some ~27 years ago, a lot of my initial stuff was scripts. I used backticks throughout my code, executing unix commands to get what I needed. Thus, I created perl scripts. More and more, I replaced my `ls` with readdir(), and so forth. They became programs.

Same for python. If you rely on python internals (which most folks do) - it's programs. If you shell out for most of your logic, it's scripts.

At least that's my take.

This used to be true, but is no longer true - and will be even less true year over year.

Battery prices are continuing to decline. China has been manufacturing solar planels like crazy, and are now manufacturing batteries like crazy.

I'd highly recommend that you read the June 22nd 2024 edition of The Economist (https://www.economist.com/weeklyedition/2024-06-22 ). Their main feature is not their front page, but rather their "Dawn of the Solar Age" feature.

I was extremely surprised. Up until June last year I was "yeah, yeah, Solar is still for specially interested people". Now I'm in the "OK. Solar will happen no matter what, given the economics" camp.

Not american; don't know the exacting details - but my understanding is that no new projects will be approved on "productive farmland".

Furthermore; given that solar is the cheapest alternative there is per kwh - economic conditions alone will ensure that lots and lots of solar capacity will be added by enterprising individuals, and companies.

The trick is that now that battery prices are plummeting in addition, battery capacity is needed for when the sun doesn't shine, and flywheels are needed for inertia.

Even with that, it's cheaper than any other power plant solutions.

The "to poor to rapidly invest themselves" is simply false.

Egypt has a GDP of $396B . Morocco has a GDP of $144B.

To buy 1GW of Solar panels clocks in at $100M . A 10GW solar farm could be had for about $1B. ROI for such an investment is in low single digit number of years. Of course, there would be extra infrastructure investments in addition.

You're entirely right that Desertec et.al smelled of green imperialism, but implemented from the African side there's an incredible export profit to be made, and later on developed into more and larger solar farms to export even more - and also provide power for more local industry and infrastructure.

If we have a look at solar influx maps, or just have general geography knowledge, it's pretty obvious that Northern Africa has enormous available areas that can be used for large scale solar plants. And lots of them at that. They can use solar towers for nighttime generation, and large areas filled with solar panels for daytime peak generation.

North Africa can, by investing on their own, become entirely energy independent. If they buy up some of the Chinese panel overproduction, and then generate their own expertise in installing large solar parks, they can easily supply domestic needs - and with cables, they can sell a heck of a lot of energy to an energy hungry Europe.

This again can be supplemented in both Europe and Northern Africa with grid scale battery storage, for nighttime usage. Northern Africa should of course invest in solar towers too - to ensure nighttime generation is also existent.

There's more than enough available space. The enormous untapped solar energy resources can be used for both export and for large domstic benefits such as water desalination etc.
