>The cost of solar panels is plummeting, and this will flood the power grid with cheap electricity. But that’s just Act 1. We won’t stop building solar at the limits of the grid – we’ll build a lot more.
Yes. Eventually more and more households will be energy self-sufficient (or better). And not just from solar. There’s other sorts of alternative energy generation tech coming, too, which will surprise many folks not keeping abreast of the developments.
With the way Russia keeps destroying centralized energy production sources in Ukraine, if the war lasts another year or two, we may see Ukraine adopting the new smaller scale energy production sources faster than anyone else. That could make Ukraine an ideal test bed for this sort of R&D on the behalf of western tech companies wanting to profit from the coming new paradigm.
unless we develop good and relatively cheap energy storage
Iron rust batteries are coming that will cost three hundred dollars. They will last as long as your house. You will just store electricity and won’t really think about it. Just the washing of solar panels once a year.
I’ve been waiting for years for this to happen. Not sure why development stalled so hard.
I think our major problem relies on the efficency of solar panels itself.
With our tech, solar panels only capture 15% of energy.
In theory, the max we could boost this number is around 33% we are only at half our potential. Got a feeling once we figure out how to tap into that potential more adoption would come.
This is anti consumer bullshit. I understand these power companies have to make money but electricity is also a given right. The cities or states need to take over at that point and distribute it so everyone has access instead of disallowing it because it’s “too cheap” what the fuck is that. These dinosaur electric companies are grasping onto old business models when the world is changing so instead they stifle innovation and fuck everyone over instead.
That lump will be spread out for longer time, as we get more vertical double sided PV.
it could be therefore more than 6 hours
If the cost of solar is plummeting why havent solar panels gotten cheaper for personal use in the last 12 months?
Good the answer to the energy capacity crisis I keep hearing about.
I’m all for renewable energy, but one I’ve learned watching some electrical engineers is that is more complicated than you think. The grid is a delicate balance of many factors including generation capacity and frequency, demand, types of power generation, inertia in the system, and more.

I say if there is excess energy do some hydrolysis and collect hydrogen. Convert a generator to run off hydrogen power then you could get a decent backup plan for when there are low power days.
Good. Power is a utility, not a for-profit business.
Very interesting read. This passage struck me a bit
>The question “can we build processes that use free energy one quarter of the time” is one of the most important and unexplored questions in the future of energy.
I think the easier way would probably use infrastructure we already have on max output. I can see AC trying to freeze water after the room temperature is low enough, so the block of ice will help cooldown after the sun has set.
I think residential thermal storage is the perfect energy sink.
If it becomes too cheap, wouldn’t that deter further investment in solar? One of the major incentives for people to get solar panels is that they can get a good return on investment compared to getting their energy from elsewhere.
We are seeing this on a micro scale. We have been completely offgrid for power for 15 years with a 24v system of 2 kW of solar and 10KW of storage, plus 8kW diesel generator for inclement weather. We recently upgraded to a 48v system of 8.5 kw of solar and 40kW of lfp storage, the generator has not come on since the upgrade, even during rainy weather. Sooo, we added 2 Mitsubishi heat pumps and minisplits, so long swamp cooler and propane heater. On top of that, we now have a PHEV car and I fire my pottery kiln 100% with solar electricity. On a normal daily basis we still generate far more than we can use.
Good it becomes too cheap we all have them
On our roofs. Sod the electricity companies.
Energy becomes as free as air.
Oh look, is that a post scarcity civilisation?
Some company somewhere will find a way to monetize it even if it ever gets to the point of being too cheap to meter
When is this gonna happen? An install on my house to give me 75% of my power needs is 40k CAD.
the power grid and infrastructure should never be attached to profits anyways. energy should be entirely free and environmentally friendly. that’s what an advance civilization represents.
if energy has a cost to it and needs to generate a profit to operate, then we’re very primitive as far as civilization goes.
