why woods do not radiate electricity?

Answer 1

Radiate?

Woods are insulators, and do not conduct electricity, so if you place an electrical charge on some wood, it does not move.

I frankly am uncertain what you mean by radiate electricity.

Answer 2

Trees can, however, reflect radio and TV waves, and are a major cause of annoying "ghost reflections" and bad TV reception in heavily forested rural areas.
