Well the technology is in its infancy, but we have fusion technology now, technically. It's doing it on a commercial scale that's given us trouble. We're getting close though. Here's a guy named Steven Cowley, explaining it a bit. In the video, he estimates in the 2030s around 9:10: https://www.youtube.com/watch?v=S6BLFdBfgfU You'll also note that around 8:24 he mentions "switching it on again in 2013 and breaking all the records." Truth is they didn't switch it on, they just started construction on it in 2013. Here's an article on that: https://www.independent.co.uk/news/science/one-giant-leap-for-mankind-13bn-iter-project-makes-breakthrough-in-the-quest-for-nuclear-fusion-a-8590480.html You'll note in that article that it explains that this 2030 estimate is actually for the first demonstration power plant. It's estimated that beyond that, we won't see nuclear fusion operating on the same scale as say, coal right now, until the 2050s. If this is all still on schedule, we'll see what's known as "first plasma", the first successful demonstration of the experiment, in the mid 2020s, so pretty soon. Maybe even during Bernie's administration, and if it does, you can bet he'll jump on board the fusion train. Oh, and that's just the public sector. Here's an article on the private sector, which claims it'll have energy on the grid by 2030: https://www.bbc.com/news/business-46219656 I don't really believe them, because they're just hyping things up to please investors. I don't believe the Chinese saying they're close either, because they're known to lie to boost their ego. Edit: The editor isn't loading for me and the formatting is getting all fucked up.

While I do agree we need to decarbonize asap and that renewable energy should make up for a lot of that, if not all, nuclear can help us out a lot with our ever increasing demand of energy moving forward. We should at least consider it, not explicitly state in the plan not to and be anti-nuclear. How far are we along to making fusion energy viable because I really don't know?
That's actually pretty exciting that it can be a really excellent source of carbon-free energy in the future. It seems fusion is a lot more efficient, safe and better for the environment than fission. I had some vague idea of it but I didn't know nuclear fusion energy was a thing we were actively pursuing until this exchange. You learn something knew everyday.
