How do you keep up with news in a particular sector?

I'm interested in this as well. Also what kind of news outlets? I find that traditional news media is often behind a community of insiders if you can find them on Twitter or something like it.

What’s the sector?

> I considered using an RSS reader, but with advances in LLMs, I am wondering whether anyone uses an LLM for this reliably.

If RSS feeds are available then perhaps do that and get the LLM to read those if its too much info, rather than llm going to x number of websites.

Depends on the niche. For your niche of choice (energy, power generation and energy markets), I'd look for industry publications (both magazines and news sites), corporate press releases and news, academic papers on related topics, discussions on any energy industry specific forums or discussion sites, etc. Honestly, that's how I'd keep up with more traditional industries.

But that's an industry I imagine has an older audience and probably relies on more traditional sources of information. For something like a video game series (or game development project), musician/band, film series/TV show, book series, etc, my method of keeping up with the news would be more heavily centred around social media posts, subreddits, Discord servers, etc.
