I guess somewhat of a fun fact: Albania has rented(!) two floating(!) oil-powered power plants near the city of Vlöre that are there in case of emergency. The last time they were really needed was in 2022 (if I remember correctly), but these days they're not turned on any more than they need to be to make sure they're operating properly. That very expensive backup system is basically the only non-renewable source in the whole country, and most of the time it's just sitting there doing nothing.

Being powered almost entirely by hydro means that the system is highly susceptible to droughts, so then they either have to spin up those oil plants from time to time or import electricity from abroad. I think it's also worth pointing out that nothing really changed because of climate change, the decision to rely on hydro was made in the 90s. The country used to have its own oil power plant that it heavily relied on before that decision, which slowly produced less and less until it was shut down for good in 2007. Some images of it from 2019: https://www.oneman-onemap.com/en/2019/06/26/the-abandoned-po...

fun fact for Paraguay: the Itaipu Dam is one of the largest in the world located between Brazil and Paraguay, where each country gets 50% of the production. But 50% of that production for Paraguay, a country of 7 millions inhabitants, means that it cannot consume that much, so it's essentially reselling that energy to Brazil, a country with 30x more inhabitants. Paraguay only uses about 1/3 of its share (and thus resells 2/3 to Brazil).

>So, the lessons for all other countries in the world is pretty clear: grow yourselves some mountains, dig yourselves a big river, and dam, baby, dam !!

It is a relief that Environmentalists have decided that hydro counts as "renewable" energy! When I was in school, hydro was considered really bad for the environment, and projects like the Hoover dam and Yangzie River dam were "not helping"

And have either a small population or a very low per-person energy budget.

But: 7 isn't the number that matters, what matters is that next year it will be 8 or 9. That would be worth documenting.

Well hydropower is the "easy" level of the decarbonization game. So it's not really surprising first countries to leave fossil fuels behind are also countries with mountains and rivers.

Or, more charitably: use the Strangler Fig method to modernize your systems, and start with low-hanging fruit.

> 22,67% of electricity consumed by Albania is imported from Greece, which generates 22% of its electricity from gas. Interestingly, Albania exports about as much to Montenegro as it imports from Greece.

There is solar on my roof. It makes about 125% what we use, but we import power from the grid every day, usually early am before the sun is up, or most days in winter.

In summer we are fully charged and exporting from about 1pm-6pm, with the line out maxed (at a pitiful 5kW, screw you Vector. New Zealand).

I’d guess Albania has the same issue when it isn’t sunny.

You're forgetting corruption. Many countries can easily go 100% renewable, but there is no profit for dictators/politicians to do so. Most of africa, or the middle east, yet you still have many regions without electricity or water, so that people worry about food for tomorrow instead of better governance in the future.

I'm wondering how this picture holds up if we include cooking and water heating.

I guess if you're not allowed to use solar in the form of chemical potentials frozen long ago into carbon-y molecules buried underground, the second best thing is to use solar in the form of gravitational potential stored in water molecules that's constantly getting replenished because the planet just happens to work like that.

Also half of these countries have frequent outages. Not sure it is much of an example for anyone else (though I frequently hear experts advocating for outages in western countries, i.e. you won't be able to run your washing machine when you need it, it will be up to how much electricity there in the grid - they call that progress).

wasnt New Zealand also already far up beyond 90% renewable electricity a couple of years ago?

Hydro electricity is also one of the most dangerous forms of energy production:

(This is the worst disaster, but could put Chernobyl to shame?)

Iceland has been selling credits aggressively so my electric bill will include nuclear and coal power

They worked within the constraints of their own topography - good and bad - to make it work. That is too hard for everyone else?

Came to say that, every time you'll see a country running on 100% renewables for an extended period, it's going to be hydro, because it's the only controllable supply among renewables (with geothermal as well, but it's been so niche so far I put it aside, but I hope it will change).

Unfortunately most of the hype and investments go to solar and wind power, which fundamentally don't offer the same capabilities. (Solar is fine as long as you're in q sunny place that is not in Europe though because it can be predictable enough to be relied on, but Solar in above 40° North and wind are borderline scams at this point).

I think they missed Uruguay which is a similar case. They have also traditionally benefitted from a hydro able to cover 80-90% most of their needs but they made a concerted effort to fill the entire remaining gap with wind and solar.

Makes me wonder why solar is not on the list.. I thought all gore said that was gonna solve all energy problems. (Of course not, he's a politician, but I'd have expected to at least see it with some relevant percentage in the African countries) Or could it be that solar is distributed enough to not appear because it's set up directly by/with the consumer rather than the grid producer?

For some it's an eye-opening experience when they compare the states which are the most vocal about going solar and have a look onto the solar map of the world.

Or then they talk about how some countries have miraculous levels of an energy independence and social services and then look at their total population.

Ultragrav (YC S27). We plan on generating the geographic tyranny of who has rivers and mountains and who doesn't by seeking to use ultrasonic audio to disrupt gravity so you don't have to hear it. We're hiring in Kansas city, KS.

In all seriousness, thereis of course a list on Wikipedia of countries by renewable electricity production [1]. China leads here but also has 1.4B people and still has significant coal usage and oil and gas imports. But they're working really hard to wean themselves off of fossil fuels while still rapidly industrializing.

China does have mountains and has built the Three Gorges Dam, which is just massive and produces ~22GW. They're building a dam that'll produce almost three times as much power, the Medog Hydropower Station [2], which is planned for ~60GW.

The part that annoys me about a lot of developed nations is that they engage in greenwashing by simply exporting their emissions to poorer countries eg [3]. Let's at least be honest about what fossil fuels we continue to use and the emissions we indirectly create.
