speaking of yarn ive been meaning to ask since ive heard of it elsewhere, is the general quality of yarn you can get going down? ive been looking into fibercraft but ive been told its getting harder and harder to find actual good thread without some sort of plastic in it, especially for a good price. so ive been wondering is this true or was it made out to be a much larger problem than it really is (in your experience)?
i've only been into crochet for a couple of years, so i'm not a Fiber Arts Veteran who can tell you the difference between shopping for supplies now vs 30 years ago! i don't really have anything to compare Current Yarns to.
in my experience, the only thing i can speak on is cost, and it seems like the cost for yarn has probably been going up. animal fibers are certainly more expensive, acrylic yarns are budget-friendly but are synthetic, if that's something you're worried abt.
so i don't think that stuff is Untrue, but i also don't think it's any reason at all to avoid getting into fiber arts, and you can absolutely find yarns made from cotton / wool / bamboo fiber and stuff like that for good prices! it would probably be harder in-person, like in the aisles of a hobby lobby. but i think lion brand and lovecrafts are good sites to browse for yarn/supplies.
it's really not a small-scale problem, someone like moi who's recently gotten into crochet and does it for funsies based on my whims/needs isn't going to really notice, i don't think.
as an aside, if we're talking about crochet specifically, you can really crochet with anything at all- i've been making a tote bag out of plastic grocery bags, lmao. reduce reuse recycle or whatever. people will also use strips of fabric instead of yarn, and that's good for stuff like rugs / bags / baskets, chunkier projects. (though ig you could probably make some clothing if you cut the strips of fabric thin enough.) so as far as accessibility to the craft, there is that!

How a simple fix could double the size of the U.S. electricity grid. (Washington Post)
There is one big thing holding the United States back from a pollution-free electricity grid running on wind, solar and battery power: not enough power lines.
As developers rush to install wind farms and solar plants to power data centers, artificial intelligence systems and electric vehicles, the nation’s sagging, out-of-date power lines are being overwhelmed — slowing the transition to clean energy and the fight against climate change.
But experts say that there is a remarkably simple fix: installing new wires on the high-voltage lines that alreadycarry power hundreds of miles across the United States. Just upgrading those wires, new reports show, could double the amount of power that can flow through America’s electricity grid.
“This is something that could be a triple win,” said Brian Deese, an innovation fellow at the Massachusetts Institute of Technology who headed the White House National Economic Council under President Biden until early last year. “A win for the electricity system, a win for utilities and a win for consumers.”
Since Biden signed the Inflation Reduction Act in August 2022 — pouring hundreds of billions of dollars toward the build-out of clean energy — experts have warned that without a dramatic increase in the size of the electricity grid, most of those new wind and solar farms won’t be able to plug in.

Many renewables are stuck in the “interconnection queue,” a long line of projects waiting to get connected to the grid. According to Lawrence Berkeley National Laboratory, more than 1,500 gigawatts of power, mostly renewables, are waiting for approval to connect. (That’s more than one-third of all the power produced in the United States.)
One of the main reasons for that long wait is that the nation builds transmission lines — those giant, high-voltage wires that carry power across large distances — extremely slowly. The average transmission line takes about 10 years to complete, and the country has been building even fewer lines recently than it did a decade ago.
Without enough power lines, there is nowhere for new solar, wind and battery power to go.
“We have to be able to integrate all this low-cost, renewable energy fast,” said Amol Phadke, a scientist at the University of California at Berkeley and Lawrence Berkeley National Laboratory.
That’s where replacing the country’s power lines — or “reconductoring,” as engineers call it — comes in.
Most of America’s lines are wired with a technology that has been around since the early 1900s — a core steel wire surrounded by strands of aluminum. When those old wires heat up — whether from power passing through them or warm outdoor temperatures — they sag. Too much sag in a transmission line can be dangerous, causing fires or outages. As a result, grid operators have to be careful not to allow too much power through the lines.
But a couple of decades ago, engineers designed a new type of wire: a core made of carbon fiber, surrounded by trapezoidal pieces of aluminum. Those new, carbon-fiber wires don’t sag as much in the heat. That means that they can take up to double the amount of power as the old lines.
According to the recent study from researchers at UC-Berkeley and GridLab, replacing these older steel wires could provide up to 80 percent of the new transmission needed on the electricity grid — without building anything new. It could also cost half as much as building an entirely new line and avoid the headaches of trying to get every state, city and even landowner along the route to agree to a new project.
“You’re not acquiring a new right of way; you’re not building new towers,” Phadke said. “So it can be done much faster.”
