It was (very probably) mostly the electric energy, which was during the "electromagnetic explosion" induced inside plants, in their tissues. Another part of the energy may be supplied with electrostatic induction, and other by direct conducting of electrical current through highly ionized gas in the immediate vicinity of any high voltage discharge - photo, drawing - here a few tenths of mm, lightning several meters or even many tens of meters (as well as the corona discharge, drawing).
Ito ay (napaka-malamang) karamihan sa electric enerhiya, Nitong Aling ay ang "pagsabog ng electromagnetic" sa loob-sapilitan na halaman, sa kanilang tisyu. Nabigyan na ang isa pang bahagi ng enerhiya ay maaaring may electrostatic induction, at ang iba pang mga ng pagsasagawa direktang electrical kasalukuyang sa pamamagitan ng mataas ionized gas sa agarang paligid ng anumang mataas na boltahe naglalabas - photo, drawing - Narito ang ilang mga tenths ng mm, kidlat ng Maraming mga metro o kahit maraming sampu-sampung ng mga metro (pati na rin ang korona naglalabas, drawing).
