Most expensive electricity in the contiguous United States. By quite a margin.

By contrast, Georgia, which has to pay for the "disastrous" Vogtle 3/4 nuclear construction project, pays less than half that.

Remember: disastrous nuclear projects are significantly better than renewable successes.

Albania: 90% Hydropower, $12150 GDP/person

Bhutan: 99% Hydropower, $ 4700 GDP/person

Nepal: 23% Imported $ 1381 GDP/person

            rest Hydropower  (2/3 of energy: firewood etc.)

Paraguay: 100% Hydropower, $ 7990 GDP/person

Iceland: 99% Hydry/Geo, $90000 GDP/person

Ethiopia: 88% Hydropower, $ 1350 GDP/person

DR Kongo: 98% Hydropower, $ 760 GDP/person , 13% of country has electricity

Not sure how this is applicable (and in many cases: desirable) for countries that do not have significant hydropower potential or maybe want a GDP greater than $760 per person per year.

> whether push-pull as TFA understands it has much to do with Conal Elliott’s definition.

Virtually nothing that is getting sold/branded as "FRP" has anything to do with Conal Eliott's definition.

I once gave a long talk about this here in Berlin, but I don't remember if there was a video.

I've also explained it on twitter a bunch of times, including this memorable sequence:

Kinda like the Marshall McLuhan scene in Annie Hall ("if only real life were like this")

And before there was "reactive", there were (oneway) dataflow constraints.

And a lot of literature on the algorithms.

I wrote a bit about the connection here:

https://blog.metaobject.com/2014/03/the-siren-call-of-kvo-an...

(It starts in a slightly different place, but gets there)

Also about constraints as an architectural connector.
