It could be used in a context where you are categorizing a group of energetic individuals or entities, but it needs additional information to be meaningful.
Example: "In our study, we identified a class of energetic particles that exhibit unique properties."
Alternatives: "a category of energetic" or "a group of energetic".
Volker Bromm, a theoretical astrophysicist at the University of Texas, Austin, says rapid rotation "could also lead to a special class of energetic supernova explosions called hypernovae, with unusual chemical abundance patterns".
A self-desensitization effect caused by the reversible thermal trans cis isomerization process was firstly proposed to explain that the azofurazan and azoxyfurazan compounds are class of energetic materials with lower sensitivity.

Triazoles are a class of typical nitrogen-rich compounds, which have been widely used in novel energetic materials, medicine, catalysis, and other fields [1 4].
These energetic cores, which emit copious quantities of X-rays and gamma rays, are termed active galactic nuclei and include the object Cygnus A and the nuclei of a class of galaxies called Seyfert galaxies.
When I was teaching a class of 8th graders in Charlotte, NC, there was a student -- I'll call him Robert here -- that had a very energetic, attention-seeking personality.
The scaling behavior of different classes of energetic particles in dipolar and quadrupolar paleomagnetospheres was investigated by Vogt et al. (2007).
