energy
'die Energie' and 'die Lebendigkeit' are close in meaning when it comes to activity and strength. 'Energie' refers more to the strength a person has in order to do something. You can have a lot or a little energy. 'Lebendigkeit' describes more the impression that someone or something seems full of life, movement, and dynamism. This can apply to a person, a conversation, a city, or music. The words can be confused because something lively often also seems energetic. In practical terms: 'Energie' describes inner strength, while 'Lebendigkeit' describes the lively effect something has outwardly.
