Pakistan has imported almost 45 gigawatts worth of solar panels over the last five or six years, which is equal to the total capacity of its electricity grid. Almost 34 gigawatts have come in only in the last couple of years.
It’s a very bottom-up revolution. This is not government deciding this is the route to take. And it’s not being driven by climate concerns, it’s all about the economics. Renewables are out-competing the traditional sources of energy.
Even in Gaza Strip you'll see sometimes solar panels next to the refugee camps, and broken ones on top of the ruins.
Further, environmental protection is not a luxury good, it's a long term investment. Ask me more in another 30-50 years when the larger impacts of climate change are happening. Or ask someone else about how much we've spent on superfund cleanup sites.
Environmental protection is a luxury good in economic terms. The Environmental Kuznets Curve is compelling to me. It's extremely difficult to assess the ROI on long term investments, particularly when your country has unstable rule of law or conflict.
I'm pro-solar, it's amazing technology that empowers individuals and communities. I just don't agree that everything I love I must force other people to pay for.
Rethink your position because it's completely upside down
Probably, but I also haven't been rich all my life, I've also been broke and borderline homeless, and my point of view of paying taxes so others get helped, hasn't changed since then. In fact, probably the reason my perspective is what it is, is because money like that has helped me when I was poor, and I'd like to ensure we continue doing that for others.
And I agree, poor countries can't afford to think about "luxury problems" like the pollution in the world, but since we're talking about people living in such countries where we can afford about these problems, lets do that, so the ones who can't, don't have to. Eventually they'll catch up, and maybe at that point we can make it really easy for them to transition to something else?

Tell that to places like Pakistan where solar is allowing people to have cheaper electricity without connecting to the grid
Solar is great. It can stand on its own without subsidies.
Maybe there is an argument to be made, but it sounds like a very poor one if poor countries are now putting up solar panels because it's the cheapest form of energy production. Sounds like subsidizing the same panels going up on houses is a bit silly now that the costs have shifted so much.
The argument can probably be made for direct subsidies of R&D for bleeding edge solar tech, and perhaps even battery installations to get volume up. Or maybe even subsidizing local production vs. buying everything from China.
The arguments for wealthy countries to subsidize their wealthiest citizens to install solar for personal gain seems rather weak at this point in the game. It certainly made sense 20 years ago, but in most areas where it makes economic sense to begin with solar penetration has hit a tipping point.
You don't know this, and to some degree likely cannot know this.
But at a national level the data is compelling. I'm convinced by the Environmental Kuznets Curve.
Which data do you find compelling?
For people who don't know the Environmental Kuznets Curve is basically the hypothesis that as economies grow past a certain they naturally start to cause less environmental damage.
As far as I can tell the main empirical evidence in favour of this is the fact that some western countries have managed to maintain economic growth whilst making reductions to their carbon emissions. This has, of course, partially been driven by offshoring especially polluting industries, but also as a result of technological developments like renewable energy, and BEVs.
On the other hand, taking a global sample it's still rather clear that there's a strong correlation between wealth and carbon emissions, both at the individual scale and at the level of countries.
It's also clear that a lot of the gains that have been made in, say, Europe have been low-hanging fruit that won't be easy to repeat. For example migrating off coal power has a huge impact, but going from there to a fully clean grid is a larger challenge.
We also know that there are a bunch of behaviours that come with wealth which have a disproportionately negative effect on the environment. For example, rich people (globally) consume more meat, and take more flights. Those are both problems without clear solutions.
(FWIW I agree that solar power is somewhat regressive, but just for the normal "Vimes Boots Theory" reasons that anyone who is able to install solar will save money in the medium term. That requires the capital for the equipment — which is rapidly getting cheaper — but also the ability to own land or a house to install the equipment on. The latter favours the already well off. There are similar problems with electric cars having higher upfront costs but lower running costs. The correct solution is not to discourage people from using things, but to take the cost of being poor into account in other areas of public policy).
Also, you keep ignoring that the environment is a public good. Poor people in Canada will also be disproportionately impacted by bigger temperature extremes (heat waves, extreme cold), worse air quality, etc.)
To be clear, I don't think rooftop solar subsidies are the best use of government money either. Governments should subsidize utility-scale solar, EVs, efficient buildings, and mass transit. They should focus on cheaper and more efficient permitting, and better grids.
It’s not that they’re paying more than rich people. It’s that even with progressive taxation, tax(everything the government currently spends money on) < tax(current spending + solar subsidies). That is to say… giving solar subsidies to rich people causes the tax paid by everyone to increase. Those making more money pay a larger fraction of the increase because of progressive taxation but everyone who is paying taxes pays incrementally more when the government spends more money.
Do you want to guess how cheap solar will be in 10-20 years, and how much power we could generate in the mean time.
This is not a discussion worth having.
The efficiency of solar does not matter in 2026. Panels are so cheap that just you don't have to think about it if you have abundant land. If solar is 4x less productive in the winter you just build 4x as many panels. Panels have to be angled more vertical the further north you go so the snow will just slide off. They are not "non-operative 3-4 months a year" - this is just Big Oil FUD.
So filling Canada with panels because they're cheap isn't likely the best environmental choice, on net. Though I admit I haven't done the math here, it's just an intuition that "just build 4x panels" isn't the solution.
As for
> those panels themselves take energy and rare earth minerals to create
You've swallowed Big Oil propaganda and are choosing to parrot it without thinking. The actual truth?
"Every year, [ICE vehicles] consume over 17 times more tons of oil (2,150 million tons per year) than the amount of battery minerals we’d need to extract just once to run transportation forever. Even when including the weight of other raw materials in ore and brine, one-off mineral demand would still end up over 30% lighter than annual oil extraction for road transport. And unlike minerals, oil products are promptly burned in internal combustion engines and must be replaced each year, forever
Admittedly this is about minerals for batteries. But solar panels are also recyclable.

This is one of the major design problems of SMRs (along with the abandonment of economies of scale).
Why can't they sell nuclear plants abroad? Sure Western countries won't buy them but the rest of the world probably would if the price were right.
this is not a matter of some fictional invisible hand. these are decisions made by real people who do not care about you, society, the health of the environment or the people who inhabit it. stop carrying their water.
I see this lie repeated in many places. Environmental protection is much, much cheaper than the alternative.
That's because you're rich like most people on HN.
Environmental protection is a luxury good. This has been proven time and time again.
A great reason to prioritize growth and wealth creation. Poor countries don't make those tradeoffs, they're worried about survival not what percentage of their energy usage is renewable.
