    We are currently undergoing the greatest transformation in energy infrastructure since the start of the industrial revolution. Solar power and batteries are not only growing, but absolutely exploding.

    Solar has become so cheap so fast that it’s going to fundamentally change the very way we use power and energy as a civilization. Seriously, look at new power generation by source. It’s almost all solar and wind, with a bit of nuclear and natural gas as a rounding error. And really, new power generation is majority solar.

    The key thing is that solar is a technology that can be mass produced in absurd quantities. And the more we produce, the cheaper we can produce it. It appears now that solar is this epochal leviathan, a glacier sweeping across the energy landscape that will grind everything else to powder before it.

    We have a very clear path to a grid that is almost entirely solar and wind. There’s nothing wrong with nuclear, but it cannot even begin to compete economically against the tsunami that is the solar revolution. Hell, I expect the grid to be almost entirely solar in the future.

    Obviously the Sun doesn’t shine all the time, but panels have gotten so cheap, so fast, that a lot of these problems are just being carried away by the solar tsunami. For swings over the course of a day, batteries are getting so stupid cheap that we’re going to have no problem making enough power during the day to meet our needs at night. But the bigger concern was always seasonal variation. How can we possibly store enough energy to last through a winter? In years prior, this was seen as the Achilles’ heel of a largely solar grid. To store that much energy in batteries would seem completely impossible.

    But it seems the seasonal problem is going to solve itself. You see, if solar power gets cheap enough, you can start doing really wild things with it. Even on a snowy day in winter, solar panels still generate some electricity. They may only generate 10-20% of what they do on a clear summer day, but they still generate power. And if solar is cheap enough, you can simply size your system so stupidly large that you can meet even your winter’s need without any seasonal energy storage. If you spam enough solar panels, you can meet your needs in the winter and then have dirt cheap, essentially free power the rest of the year. And it really looks like this is where we’re headed.

    I foresee that many of our most energy-intensive industries will adopt a seasonal or semi-seasonal schedule to take advantage of the dirt cheap power in the warmer months of the year. We have a crop growing season, why not an aluminum smelting season or an AI-model training season? Or that free summertime power could be used to desalinate vast quantities of seawater affordably. Or, such a low-cost energy source is exactly what we need to make bulk atmospheric carbon removal a real possibility.

    We used to live in tune with the cycle of the seasons. We lived according to the cycle of the Sun. So important was the Sun to our ancestors that we named our greatest deities after it. Amun. Aten. Ra. Huītzilōpōchtli. Ba’al. Aryaman. Mithra. Apollo. Helios. Sol Invictus. These were but a handful of the thousand names we gave to the mighty Sun upon which we so depended. We rose to its light and slept in its absence. We worked when it shone brightest and in the winter, invented elaborate holidays and rituals to encourage its return. We built our entire calendars and organized our entire civilizations around its cycles.

    With the Industrial Revolution, we abandoned this close relationship with the Sun. We learned to draw upon bottled remnants of old rotted sunlight, and for a time learned to live apart from the mighty Sun. And those energies in fossil fuels improved our lives so greatly; they raised us up from the mud. We improved our standard of living so much, that we would rather burn the world to ashes than give up the lifestyle we have grown accustomed to. And so, the great challenge of our age is to find a way to keep our lives and comforts going, without destroying the Earth in the process. Millions of people have dedicated their lives to this one central challenge of our age. All our efforts. All our sciences. All of our industry. Our brightest minds and every tool of finance and government at our disposal. All of it searching, seeking, trying to desperately to find a way out of this horrible trap that we have built for ourselves.

    And now, after all this yearning. After all this wondering. After all this wandering. The solution was in front of us this entire time. A ray of Sunlight has been cast down into the cave that we are so lost in. And it is leading us back to the light. We will cast off these shackles and leave the fossil fuels in the dust where we found them. We will once organize our entire civilization around the infinite bounty that the Sun freely gives in such abundance. And we will continue to enjoy the fruits that science has given us, but in a way that not only does not damage the Earth, but allows it to heal. That is the future ahead of us. That is the light in the darkness. As our ancestors did from time immemorial, we will once again live in the endless generosity of the star that birthed us. And we will rejoice. And we will sing.

    Sol Invictus. We are coming home.

      Whilst it’s true solar is growing, it is not likely to be the silver bullet you make out.

      Another way to look at the source you linked is that despite the ongoing climate catastrophe the US is still planning to add 4% more fossil fuel sources to their grid next year.

      It also leaves out the fact that 84% of the current US power is generated by fossil fuels and that figure is not being reduced.

      The source is also very US-centric. If we take the IEA’s projections, only 25% of the world’s new energy will be from renewable sources in 2024.

      Then there’s the weird choice of counting battery storage as energy generation. At the end of 2022 half of the battery storage was being powered by fossil fuels so should probably be left out of any statistics.

      We need people to understand the true scale of the problem rather than generating more hopium. The energy companies have teams of people for that.

          As of 2023, solar energy accounted for about 4.5% of China’s total energy consumption.

          In 2024 solar energy could account for around 5-6% of China’s total energy consumption.

          If they add another 170GW in 2025, the percentage could rise to approximately 6-7%.

          They hope by 2026 solar will make up 8-9% of the total energy consumption.

          If solar is the future then we are screwed because that isn’t fast enough growth… and that is without factoring in the rest of the world who will hit nowhere near those numbers.

            And they are adding, fast. Far faster than we are. That goal of nearly ten percent solar in less than two years?

            That’s not only fucking amazing, that’s achievable, and they’re on target for it.

            As cheap as panels and controllers and batteries have gotten? It’s only getting better.

              Yes they are the leaders in solar which is they are a good example… If the rest of the world was going at thier pace (it’s not) it still wouldn’t be fast enough.

              Then we’ve got the degradation to worry about so the panels will all need regularly replacing whilst silver, gold and rare earth metals run out.

              Rolling out that infrastructure is not likely to be smooth whilst most countries will be busy footing bills for the ongoing extreme weather. Not to mention the other potential blockers like wars, pandemics and lack of political will.

              That last line sounds boundlessly optimistic and condescending in equal measures. Magic is real lol please. Of course I know sunlight comes from the sky and electricity can be used to play games consoles.

                Ah, typical human problems that disrupt regular power generation is somehow specific to solar?

                Nah, wars and climate change fuck with the grid already, just ask texas. Or north carolina. Or palestine.

                And panel degradation is wildly over exaggerated.

                My old as fuck mono crystalline panels (I have owned for ten years, and they were outdated when I got them) still kick literally 99% of their sticker rated juice. Even when dirty. They’re dirty right now. I’m not bothering to clean them, cuz they still kick every volt they say they will.

                They also literally produce all of the electricity my entire household needs.

                SOLAR IS BETTER THAN YOU ARE WILLING TO ADMIT

                And yeah, I probably pwned your ass at fortnite or rocket league or something

                On solar power

                  Oh dear someone has had a tantrum and resorted to shouting and ad hominiums.

                  I know solar is good and sounds like it works well for you in your part of the world. My only point is that it’s not going to solve climate change like you make out.

                  I don’t play Fortnite or Rocket League lmao.

      I’ve actually been shocked by how little production drops during winter. For example, we Feb & March, our coldest months this year, we produced 1.75 MWh/month, which actually beats every summer month before it, and is only beaten by this August, which was our highest producing month ever at 2.04MWh. Most summer months before that were closer to 1.5. Only thing I need to do is clear the panels after it snows.

        What is likely the cause of this is one thing that people miss about solar panels. Their efficiency is a function of temperature. In the summer, you get more sunlight, but the panels themselves are hotter and thus lose efficiency. In the winter there is less light, but the panels make the most of every photon.

          Well sonofabitch.

          That explains why my setup starts cranking early in the morning, but is kinda piddly in the afternoon, when, by my eyes, there’s even more direct light on them.

          Had honestly never heard temp mattered at all

      It’s true today that you can easily drive your entire home on solar power, but only if you live in a sunny country. If I was, I would install them immediately. They will pay back in like 5 years and after that, energy costs are zero.

      I look forward to them becoming smaller and more efficient. In the future, we may be able to have glass that is made of solar panels, which means entire skyscraper buildings can charge their power continuously from the sun.

        Americans in Massachusetts are able to install solar panels and run their house.

          Shit, my panels were still kicking at 95% when covered in a layer of dirt so thick I had to hose them, and wash em twice.

          Now they’re back up to 99%, and they’re about ten years old

        Yeah, I am lucky to live in such a country and it’s amazing. The state and municipality each subsidised part of the purchase, so I ended up paying 300 something euros to install 3.5 kW of panels. My electricity bills are almost non existant during summer and also cheaper during winter. To make it even better, anytime I’m not using the produced electricity, it gets sold to the grid, even if pretty cheap, rebating on my next billing cycle.

        @1984@lemmy.today: It’s true today that you can easily drive your entire home on solar power, but only if you live in a sunny country.

        The truth of that statement is entirely a function of the price of solar panels. Again, if they are cheap enough, even on a cloudy winter day, you can power a city with them. My point is that solar is becoming so stupidly cheap that “spam solar panels” is becoming a viable option for our power production needs. Unless you live in such a high latitude that you’re near the Arctic circle, you will be able to power things off solar. Solar panels will produce power literally in the middle of a snow storm. It may only be 10% or their peak output. But if you have enough of the damn things, it doesn’t matter. And solar is getting cheap enough that this is a viable path forward. And that’s before we even talk about other energy storage methods like green hydrogen production or long distance power transport.
