You have to remember that power is energy per unit time.  A watt is a joulle
per second.  Even though a lightning strike may be gigawatts of power, it
lasts a small fraction of a second.  Millions of joulles of energy.  One
kilowatt-hour (perhaps 10 cents worth of electricity) is 3.6 million joulles
of energy.  So I'm going to state that $100 worth of energy can do thousands
of dollars of damage at times.  It's all in how concentrated the energy is
in space and time.

An article I read recently in Science News stated that some experimenters
believed that ball lightning was a concentrated plasma of mostly metal ions.
Someone was able to create something that acted like it in the lab.
