Following 35% growth, solar has passed hydro on US grid

The trump administration by refusing to admit the superior metrics of solar, they're just burying their heads in sand.
As admitting that solar is now a superior and cost effective means of energy means admitting that the US is no longer top dog.
As empires are built on mastering a source of energy.
the Portuguese | Dutch - mastered wind to power their ships.
the British mastered coal to power Industrial Revolution.
America mastered oil
now the Chinese have Solar.
even in places like Africa etc -- places were the grid was never available for $2k -- you can power your whole house with solar and lithium batteries. Panels are getting cheaper, same as batteries. Once the tipping point is reached for electric vehicles both personal and commercial - transition to fully electric mobility happens

I am reminded by the perhaps revisionist history but still applicable belief that slavery was really ended by industrialization making abolition economically advantageous and not actually a socially driven movement. (In reality it was certainly a convoluted mixture of the two I'm sure.)
I hope we are in a similar era with regards to climate change. Surely there's a lot of money to be made in harnessing effectively unlimited renewable energy that literally falls from the sky like manna. With a bit of social pressure we should be able to extinct the fossil fuel industry in my opinion.

Kind of a weird headline. It makes it sound like this just happened. But it happened almost 2 years ago. Reading the article is also a bit confusing. I finally figured out they are only referring to utility scale solar and not total solar (utility plus behind the meter)

Does anyone in these comments have any tips for would-be solar farmers or people who are generally interested in being part of building out the future of our grid? I'd like to get my hands dirty. I'm talking about getting into 5-10 MW projects, not solar on a roof.

I'm not disputing anything, but would it have killed arstechnica to include some primary source links to back up their assertions?

if this type of data is interesting to you, here’s a site I’ve built that tracks like grid data across the US and Canada: https://www.gridstatus.io/live
We have generation mix, load, and pricing data. Both real time and historical

I was curious to try a project: can I charge my car 100 miles per day for under $1000 all in?
I’m trying to source a battery power pack and cheap panels.

It's incredible to me that California's primary generation source is cyclical solar — which it primarily offloads to PNW [0], who offsets any missing California solar with its MASSIVE Columbia River Hydro.
Essentially co-dependant renewables, the entirety of West Coast through Colorado balancing primarily between solar and hydro (and natgas peakers). Nothing like Québec (¡hydro!), but still something.

If ERCOT ("Texas") would get over their independant grid "benefits" [i.e. not having to follow federal regulations], they could be sloshing their primarily wind-derived kWHs into an even more-beautiful grid of flowing renewables.
Instead, 10-year winter storms risk hundreds dead and billion$ lo$t.

TVA is in planning stages for its second massive pump-storage facility — but Texas is probably wiser in its nascent battery storage investment [1], instead. TVA's Racoon Mountain Pumphouse is definitely impressive, but with all the upcoming "depleted" car batteries being reconditioned into the stationary electric storage market... water power storage is probably the more environmentally-damaging method (definitely more expensive?).

My layperson recommendations to industry [I'm blue-collar, electrician]: reduce coal, increase nuclear; increase micro battery storage (e.g. see Chattanooga's EPB implementations); maintain but stop building dams/pumped storage.
Solar/wind/nuclear/nat.gas will be able to run everything once we have enough battery storage to handle daily peaks. In a few more years we will be entirely able to remove our dependance from toxic coal [2]

I wonder why existing hydro isn't utilized to it's potential. For instance, the Grand Coulee Dam has the highest capacity of any power station in the US of almost 7 MW but usually puts out about a third of that.

I have a goal of setting up solar on my property in the woods that goes directly to a wall of batteries, maybe Tesla, maybe something else. But definitely not going back into the grid. Does anybody have suggestions or advice on how to do this?
Who are the best companies doing this right now in New England? What products are folks using to store electricity? Are there any good resources for this kind of thing?

Happy to be a 5 year self generation participant contributing to these numbers. Given the very recent winter storms along the East Coast, that still has people without grid power at this very moment, such a residential generate and store system should be an eye opener to those impacted at times of greatest need. My own system was still generating during the storm as many erroneously believe the sun must be fully exposed to move electrons, nope.
I commented here in a recent HN energy post about my surrounding jurisdictions and the exploding utility costs per PJM that literally have governments suing each other. Just today one of those local jurisdictions announced a utility bill financial credit incentive for residents to attend a meeting to learn about what some already know intimately. Link is paywalled of course.

We are witnessing the accelerated adoption of local generation and storage driven by the economic costs of energy that has been directly and indirectly subsidized yet consumption is certainly not equal. As more and more move to self generate and store, per the meetings suggestion, the negative feedback loop is already in motion rising costs even more for those dependent on a centralized system.
For those that can see the light and where it is going; invest accordingly.

It's also been a great year for oil production which has reached new record highs in the US! [0]

> While the Trump administration has been hostile to renewable energy, there’s only so much it can do to fight the economics. A recent analysis of planned projects indicates that the US will see another 43 GW of solar capacity added in 2026—far more than the 27 GW added in 2025. That will be joined by 12 GW of wind power, with over 10 percent of that coming from two of the offshore wind projects that the administration has repeatedly failed to block. The largest wind farm yet built in the US, a 3.6 GW monster in New Mexico, is also expected to begin operations in 2026.
Hopecore. Onward. The horrors persist, but so do we.

Elon Musk mentioned that just a 100 square mile grid of Solar can power the entire USA. I did not believe it; a simple calculation later, I was convinced. The USA of yesteryear would have done this already and more. Sure other sources are required, but honestly we humans have to advance beyond burning dead things for fuel.

This isn't a good thing unless it's paired with storage and transmission upgrades. Every time this kind of story posts I make this same comment and am met with the same probably well-meaning but ignorant responses. Solar generation is easy and cheap and simple. Actually getting that power where it needs to be, when it needs to be there is complex and expensive. You either need to store it or you need to transmit it very long distances, neither of which we can do effectively right now. Most of California routinely goes into negative power pricing - this is not the mark of a healthy system, it represents a massive inefficiency and destabilizing factor.
We need to pressure politicians to subsidize pump storage powerplants and massive transmission system upgrades (which means being ok with permitting new transmission lines) it's simply impossible to continue increasing the solar on the grid otherwise, we are rapidly approaching instability.
