I wholeheartedly agree!
When I previously applied Haskell to cleantech, I also relied heavily on dimensional. This is one of the gems on Hackage!
I am intrigued by this line:
who I hack on Haskell clean tech with in our free time
What are you working on?
Haskell also has green threads! 
We haven’t published anything yet (we will, eventually). The examples in my post are loosely based on what we’re working on (simplified, of course).
In case it takes longer than expected, I don’t want to disclose too much publicly, yet 
What sort of projects have you applied it to?
I co-founded a startup (shut down about a year ago 
) that ran a local electricity market on smart electricity meters in the US.
The platform’s back-end was entirely Haskell: Cloud Haskell as the base platform coordinating smart meters in a peer-to-peer topology. We used javelin and beam for time-series analytics. We started implementing a Haskell client library for Enode as well, but we never finished.
We also wrote a Haskell interface to the HiGHS linear programming engine to optimize the electrical networks. I should really find some time to open-source that last part; the Haskell DSL we came up with was very nice.
Edit: We also usedalgebraic-graphs a lot to manipulate the topology of electrical networks! Damn we had a lot of fun
That’s so cool! Sad to hear it shut down.
Hey, we should have a seminar!
I have quite a Haskell codebase in our small renewable energy company, the most general parts are open source. E.g. closed-intervals to match (mostly) time intervals in timeseries, provenience to document financial calculations and a client for talking to wind farm SCADA servers.
When I needed to write a well-documented, composable simulation for Power-To-X applications, I reached for literate Haskell with just a RWST monad as the main driver. We threw lots of linear algebra at a stupid electricity tax problem. Haskell is feeding our time-series databases. All our invoices are generated through a Haskell system.

I’m curious 
Which one?
Hey, we should have a seminar!
Definitely!

A good place for functional programmers in Germany is the BOB conference. See announcement.
7 posts were split to a new topic: Energy efficiency of Haskell
This was definitely a cool blog post, thanks for sharing. I’m very much in favor of Haskell being used outside of the Blockchain and DoD lol.
