The rock type that is associated with a high-energy environment is sedimentary. High-energy environments usually produce sedimentary rocks with larger grain sizes.

a high energy depositional environment is one in which enough energy was present to transport large materials such as rocks and boulders. a low energy depositional environment like a stream is only able to transport materials such as fine sands.

so no energy, no environment

Not only does it waste electricity, but it makes your energy bill go sky high.
