1. The location of lightning is not fixed, so it is difficult to collect it by technical means.
2. The energy of lightning is very unstable, sometimes large and sometimes small, which has great security risks.
Lightning has high voltage and current, so it needs special equipment to collect energy.
4. Lightning collection needs to store a lot of charge, and there is no equipment that can store enough charge at present.
5. At present, there are still technical problems in the utilization of lightning, which cannot be commercialized.
Generally speaking, for reasons of safety and efficiency, lightning can't be collected and used as energy at present.
