You are being misled about renewable energy technology.

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.

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.

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.

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.

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

> 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.

> 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
