Years with an HN recommendation, 2007–2026

HN repeatedly recommends it as an up-to-date, fact-focused case for solar and batteries that readers can cite on land use and costs.

A long Technology Connections video arguing that public understanding of renewable energy is distorted. It covers solar economics, land use compared with ethanol corn, and battery myths such as cobalt.

“Alec Watson’s recent, and excellent, Technology Connections YouTube piece on renewable energy.” (HN, 2026)

> And no, there's no mention of batteries there; it's literally a straw man fight, showing their applicability to daily solar power generation cycles while almost completely ignoring their applicability to annual cycles. Why is it every single time someone in this thread speaks up they are just plain wrong? Here is a direct link to the part about batteries. He talks about them for about 15 minutes which is something like a quarter of the video. There is even a chapter mark to take you to that part. He also mentions them half a dozen more times throughout the video and warns in the beginning that people like you will chime in with misinformation without watching the video. You proved him right. [this video] > applicability to annual cycles. He talks about that too. I'm not going to bother linking. Actually watch the video or move on. > Just take a weekly chart of the actual energy output of the panels for the year, and calculate the price relative to the worst week I don't have to. The United States government did and even considering the cost of storage, it's still cheaper than all the alternatives. Has been for years now. See my earlier comments for links. Private investors have done the same math, and that's why almost all new electricity generation being built is solar. It's the basically free money. Nobody with a brain can legitimately think that digging goop out of the desert, doing expensive processing to it, shipping it to the other side of the earth, and literally lighting
Spends about 15 minutes on batteries and annual cycles.

on HN thread Solar and batteries can power the world
Yeah, the technology connections video on this was fantastic. If one was to cover that land in solar, you’d produce far more than the current energy demands of the US. Relying on an energy source which requires constant, continuous resource extraction is fucking stupid when we can spend resources up front and get reliable energy (solar + battery) for decades with minimal operating cost & maintenance. And then we’ll have a recycling loop to minimize future resource extraction. If you want to debate that, spend some time with this video first: [this video]
Fantastic video showing solar on corn land exceeds US demand.

> in effect you've basically hamstrung green sources of energy around the country by being very smart for your own state. > The question is, should you be allowed to this. "...you've basically hamstrung green sources of energy"? Well, after we stop growing corn to feed exclusively to cars and start using solar panels deployed on that land to harvest electricity for cars and houses and everything else that runs on electricity [0], if we're still short on power we can have the discussion you're itching to have. [0] The immediately relevant discussion starts here < [this video] > and runs through to about 38:29, but the entire video is very, very well worth watching.

on HN thread In a first, wind and solar generated more power than gas globally in April 2026
I recommend this video from YouTuber Technology Connections: [this video] I appreciate his ability to talk renewables for almost an hour and barely mention climate change. This video has a bit of a twist ending, but he gives you a solid out before he becomes political if you're showing it to someone who won't be receptive to that messaging.
Nearly hour-long renewables talk with little climate politics.

Highly recommend everyone watch this video [this video] Briefly, the most important reason an EV is better because it unlocks energy portability . You gain the flexibility to source your energy in many more ways than with a gas car. Oil energy is about as optimized as it's ever going to get. With electricity, we're just getting started.

on HN thread FERC: Renewables made up 88% of new US power generating capacity to Nov 2025
If you like (VERY) long form videos, you might enjoy the recent video about renewables from Technology Connections: [this video] Some of the interesting take ways for me, as someone who was already pretty hung ho about solar and batteries: * Solar has gotten so cheap that it's still profitable in the shady northlands * The amount of land it would take to run the US primarily on solar is "a lot" in absolute terms. But it pales in comparison to the amount of land we currently use to grow corn for feeding gas cars.
Long video on solar cost and land use versus corn.

This really illustrates how important it is to switch to renewable energy. I know it's not an easy task for impoverished communities to get the startup capital to install solar+batteries, especially one in such a politically tumultuous position, but that really is a path to stability for so many people around the world. A YouTuber known for talking about dishwashers and Christmas lights recently put out a long rant about how ridiculous it is that humanity still leans so much on single use fuels: [this video]

on HN thread Banning lead in gas worked. The proof is in our hair
It was, several years ago. That's so much not the case now that renewables + batteries were by far the largest source of new generation in the US (yes, the US, with Trump actively trying to destroy them) last year. Look up some of the new information coming out about them recently. Here, I'll give you a relevant video I watched recently to start with: [this video] (channel is Technology Connections)

on HN thread 3.4M Solar Panels
I was shocked (pun) to hear how my relatives were each reacting to solar energy. One was rural and was concerned about nearby land getting turned into a solar farm. Another was concerned about farmland being edged out in favor of solar. And a third spent some time in emergency response on a solar farm and was off-put by their vastness and the electrical danger while traversing through them. Coincidentally this video emerged within a day of my conversation with the three of them. I shared it; they probably didn't watch it but it sure was pertinent. [this video]

on HN thread Producing ammonia and fertiliser using wind power in Morris, Minnesota
Solar and wind energy have been more economical than fossil fuel on a cost per unit energy basis for quite some time. The reasons we're still so tied to fossil fuel are largely political, not economic. Technology Connections goes into this in exhaustive detail: [this video]

> There is also the need for real estate in areas with good sun exposure that also have sufficient fresh water supply for cleaning. Solar panels are 20x more efficient than growing corn for ethanol. Swap out some of those 30 million acres of ethanol corn fields (in the US) and you'll have more energy than you need. More details here: [this video]

I think the lament is the rise of the "facts are the enemy" stance is a step towards dystopia. I recently learned that if we converted all the land we use to grow corn for ethanol (not food) into solar farms the US would produce 84% more energy than it currently produces (from all sources) [1]. Of course that's a huge undertaking, but we're not even talking about it because pesky things like facts are swept aside in lieu of punchy counters like: panels are expensive (they're not), we don't have the land (we do), what about the batteries (solved problem with today's--let along tomorrow's tech), the corn best doesn't get enough sun (it does), etc. [1]: [this video]

on HN thread Total Surface Area Required to Fuel the World with Solar (2009)
Yes, and the corn-based ethanol here is used for "feeding cars" that have combustion engines, i.e. it's already used exactly for energy production. The most recent Technology Connections video[1] quoted some numbers on this. All this land dedicated to disposable energy production could be dedicated to renewable energy production instead.

on HN thread 3.4M Solar Panels
That's incorrect per the video. It wouldn't cover 80% of the current US grid it would cover 80% more! It would be 180% of total US grid usage. Timestamp of where he says that: [this video]

Haha, but you did that already: > How much CO2 is released producing, shipping, and installing the solar panels? Or maybe you wanted someone else list all the steps. I was simply helping you with the part you missed: > GP is right: you gotta consider all the variables The fact you seemingly missed the fact that growing and processing corn keeps emitting GHG (not only co2), and that producing, transporting and installing the solar panels costs *once*. I already mentioned the video that covers this specific relationship and details, the actual costs and benefits of growing corn for ethanol vs generating electricity: [this video]

Favoring emotion over facts while advocating for a cause is still a sugar high of advocacy, regardless of the cause's righteousness. A short burst quickly forgotten, with a chance of discrediting what you're trying to advocate if the facts aren't right. Even amongst YouTubers, you can favor facts over emotions (without discarding emotion!) and be a more effective advocate who arms others with both motivation and useful, effective knowledge.[1] 1: [this video]
Example of favoring facts over emotion in advocacy.
