In QGIS, using Python, how can I automate cutting off leftover arc parts?

I'm developing a potential heat network in QGIS, using an existing street map and existing building locations. I've drawn lines connecting the two and called this my house level 'heat network'. Then I've isolated the streets which connect to this house-level heat network and called it my street-level heat network.



However, I'm left with quite some orphan network (green lines on top going nowhere), as can be seen below.



Orphan heat network



My question: how can I remove those lines? I would need to do it in an automated way, since clicking takes too much time.



Thanks for your help!

          What visual should I use to simply compare current year value vs last year in Power BI desktop

          Image
          0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

          Trompette piccolo

          Ne doit pas être confondu avec trompette de poche. Trompette piccolo en si bémol, avec des branches d'embouchure différentes pour le si bémol (la plus courte) ou la (la plus longue) Trompette piccolo La trompette piccolo est la plus petite de la famille des trompettes. Elle joue une octave plus haut que la trompette standard en si bémol. La plupart des trompettes piccolo sont conçues pour jouer dans les deux tonalités de si bémol ou la, en utilisant une branche d'embouchure différente pour chaque tonalité. Le tube de la trompette piccolo en si bémol a une longueur moitié de celle de la trompette normale en si bémol. Des trompettes piccolo en sol, fa, ut sont également fabriquées, mais elles sont rares. La trompette soprano en ré, aussi connu comme la « trompette Bach », a été inventée vers 1890 par le facteur belge Victor-Charles Mahillon pour jouer les parties hautes de la trompette dans la musique de Bach et Haendel.
