The most dangerous element of this is that he said in his manifesto that he is trained in demolitions.
A long time ago I knew some Army Explosive Ordnance Demolition (bomb disposal) types. They had an ongoing contest, in which they picked a random major city in the world, and as a thought problem, figured out how it could be paralyzed, for under $500. That is, cut off its water, electricity, sewage, communications, transportation, etc.
For under $500.
They did this contest on speculation that if some other *trained* individual(s) tried to do this, they would pick many of the same vulnerabilities. And if they did, the EOD would know where to look to neutralize their bombs.
Importantly, bombing is by far the most effective terrorist attack, because it picks all the criteria of the attack, and by the time the bomb goes off, optimally the bomber is many miles away.
The best example of this was New York’s “Mad Bomber”, who blew up bombs for 16 years before being caught.

I’d say the Norway shooter was quite effective too. He lit off the bomb in Oslo, had the police from the entire southern half of Norway at the site (they have very few police in that part of the world, which is going to be a HUGE problem when it comes to even holding on to the government...but that’s another discussion), and then went to that Socialist Training Camp and shot them up - unmolested for like an hour, before anyone could get there.
