Energy conservation holds in quantum mechanics Yes, in Nature NO.

Some phenomena like Ball Lightning and comets seem to tap energy out of nothing

Sprites: Interference Micro String Black Holes 2x seem to produce free electric vacuum energy.

The Interference origin of Sprites with Ice shells : is also reason to understand the Vajra vacuum dual BH Birkeland electric energy production around the sun,  according to Q-FFF Theory.

Hollow channels formed by decaying nano interference black holes like Sprites..

Sprites: Ice Shell forming and falling down by Interference Micro Black Holes.

The origin of Ice shells or Cryo Meteors falling on Earth: Micro Interference black holes..
Mega cryo meteors fallen on earth as the remnants of micro comets nuclei, created by Sprite based interference black holes according to Q-FFF Theory.
