Ideas for 10th European openmod workshop in autumn 2019

openmod will celebrate its 5th birthday and hold its 10th European workshop in autumn 2019.

Time to start thinking how we could celebrate with an extra special event!


  • An extra-big workshop with 200+ people
  • Showcase the big open energy successes (OPSD,, SciGrid, etc.)
  • Big effort to get people outside Europe to participate
  • More institutional guests, data providers, etc.

Location-wise, the first workshop was in Berlin, so there’s a nice symmetry in holding it in Berlin again. Everybody loves Berlin.


Well, in the spirit of what I guess many of us are “really” working on (decarbonisation), how about going for broke with a nearly carbon-neutral (NCN) conference? Also speaks to the most general ideal of “openness” of course… (For more background link goodness, maybe check: “We need to talk about aviation…”…)


I really like the idea! Are there any good open-source cross-platform tools for self-made recordings, or guides how to do it? Slides with an audio recording guiding you through them would be sufficient. I love these lectures on optimal power flow:

The nearly carbon‑neutral conference (NCNC) concept outlined by Ken Hiltner (2018) offers several clear advantages: outreach and inclusion, no need to ration attendance, and less carbon. I would suggest one modification to the arrangements Ken described: the Q&A might be best conducted using online chat rather than shuttle email and limited to say two days rather than extended over several days or weeks.

In which case, this community should consider establishing a private Mattermost server (MIT license server‑side and analogous to Slack) and a private Nextcloud server (AGPL‑3.0 license), the latter for persistent presentations, associated documents, and any online collaborative editing. Both services run client‑side using current web‑browsers (including Firefox) so the local admin overhead is zero. Mattermost also offers dedicated clients (Apache‑2.0 license) for those who prefer instead to run local apps on mobile devices and laptops (Linux included).

On air travel more generally, Marks (2019), despite the upbeat title of the article, makes very similar points to @bmcm in his November 2018 blog. The airline industry (through CORSIA) has finally opted for voluntary financial offsetting for post‑2020 emissions growth as its flagship response to our climate emergency. Such measures are totally inadequate under current carbon pricing and derelict in terms of burden sharing. Better also would be a moratorium on new public-financed climate damaging infrastructure like airports until comprehensive, realistic, and fair solutions can be determined and agreed.

“Are there any good open-source cross-platform tools for self-made recordings…”?

For what it’s worth, I use SimpleScreenRecorder as my cheap (free!) and cheerful (GNU General Public License) screencast recording tool. Here’s an example talk I recorded last year (shameless plug): Where is the low carbon [sic] energy vision Ireland needs to mitigate climate change? But it is linux only - not cross-platform. So other tool suggestions would be more than welcome!

Great suggestions from @robbie.morrison: very innovative and exciting. This sounds like it really could be something worth trying in earnest!


Following up on robbie’s comment, I wonder whether the format could be further adapted, e.g. by combining an “online conference” with voice recording (for people like me, that appreciate an a bit more personal and direct interaction), an online chat or “votes” (to allow simultaneous feedback without line overload), and subsequent chat-forum (for those in different time-zones)? … To increase personal interaction, researchers from the same city could also gather in the same place and dial in together (at least for the keynote sessions)… exchange on learnings from the talks over lunch etc…
During the last calls regarding the COST Grant application, I used, which worked quite well, and also allows screen sharing, conference recording and up to 1k participants. But recommendations on other tools are also welcome :-).


The Danish Energy Agency (DEA) modeling section has offered to present their efforts to encourage greater openness in energy modeling and analysis at an upcoming openmod workshop. Please message me off‑forum for details because I am reluctant to place staff contact information on this forum.

that’s a nice idea. That will be great.
