Daytime energy is soon going to be free in much of the world. The advances in green tech, especially solar and batteries, are real. Much faster progress than even the optimists were predicting a decade ago. The revolution is reaching a tipping point where it becomes self-sustaining and requires no state subsidies. I am not a tech utopian, and this alone will not save us. But there’s no denying it’s good news. It’s all happening far too late but it does look like humans are going to kick their fossil habit after all.
Inconvenient footnote: thank China.
It’s gotten so good that China might be restricting output to keep the prices high…
(their onshore wind, and pumped hydro storage, are also great success stories, as is the EV industry there)
Indeed. China is such a paradox. An absolute anathema in terms of culture and politics. It’s almost impossible for us Westerners to grasp how a people could accept that level of authoritarianism, how they could value their personal freedom so little. And yet, and yet. Without China we would be royally screwed. They are pulling the weight of the green transition basically alone. So personally I’ve decided to hold off on China-bashing for now.

This assumes that they have an alternative to authoritarianism that they could enact if they wanted. For some reason, the authorities don’t allow that. And the authorities also don’t like when people talk about it, so it’s difficult to discuss and convince others that authoritarianism is bad.
Tiananmen Square was not that long ago. There are lots of living people who would have seen their fellow students get crushed by tanks and rinsed down a drain.
That will keep a generation and their children quiet. Their children have also now seen how risings are punished via Hong Kong.
I don’t think it’s even possible to imagine what you would do having seen your government enact that kind of violence on your peers. So I certainly don’t judge.

Optimistic of you to assume pricing is cost-plus not willingness-to-pay. US utilities (and their foreign counterparts) will only too gladly keep charging you
Agreed. In theory that problem can be dealt with by properly regulated competition.
Yes, but, we depend on fossil fuels for far more than just energy. We still get most of our plastics from them, and most of our fertilizer, without which we can’t feed most of the developed countries. And while renewables are great for stationary use, we still don’t have anything with the energy density of fossil fuels for cars, shipping, air travel, and cargo. And, whether anyone thinks it’s a good use or not, war is entirely, inefficiently, and intensely run on oil.
There are a lot of other issues entirely unrelated to power grid energy production we have to solve first, the most challenging being our own aggressive human nature. We’re a long way from kicking the oil habit.
The energy density of batteries just keeps increasing, for cars at least it’s now good enough. I agree completely about the rest but this was meant to be a happy thread! I agree with OP that we need to talk about good news too sometimes.
Fair point about positive things; I just think it’s important to not delude ourselves.
Is there a good place to ask about independent (non-grid-connected) solar for an otherwise grid-connected structure? I’d love to set something like this up, but can’t find any systems which don’t require wiring into the gird.
Why would you pass up on the free money of selling the power? You’re probably looking for a hybrid system if you just want to keep the lights on during a service outage. Or I guess you can just build an off grid system and wire it to a generator transfer switch if you want to power your house circuits but only during an outage.
Most half decent solar installers can help either way.
Mostly because I am not in a place, financially or home-wise, to install a full grid-connected system. I’m just looking for something that I can use to charge enough battery to run a lamp, fan, charge devices, or other such similar light loads on a daily basis. It won’t bring my power bill to zero, but it will chip away at it.
I’ve set up an off grid solar system out of necessity. Used to be an electrician so I know a good bit (but not everything by any means). What are your questions I can maybe point you in the right direction.
Based on your initial question, it depends on local zoning. You can likely legally grid tie a set up and have a battery backup. I think if you want to be legal I’d go that route.
If you want I think you could set up a completely separate system in a more sneaky fashion that is completely isolated from the grid / your existing house circuitry. But when grid tying (including into your house circuitry) you have to be pretty safe because that power can go upstream and feed the grid or the house when workers think the power is off, which is obviously very dangerous and could get you in a lot of trouble if it went wrong.
Engineer here, so I’m aware of the fundamentals of “how not to kill yourself with electricity”. Anything tying into the grid I’m definitely calling a professional for.
But no, I’m not in a financial or property situation to install a grid-connected system, so I was imagining a “balcony solar” kit that’d just charge a small battery bank I could run some lights, a fan, or some similar low-load devices off of. I don’t know if such a thing exists (or if it’s a smart idea), but I’d like to look into it and find out.
You wish, if we keep going towards everything has a battery power demand is only going to go up
