How much electricity is in a lightning bolt?
There are many varying answers about the electricity in the average bolt of lightning. The typical answer is that the average is about 1 billion volts at 20-30,000 amps. However, for any individual strike, specific conditions can cause incredibly wide fluctuations.
An average bolt of lightning, striking from cloud to ground, contains roughly one billion (1,000,000,000) joules of energy. This is no small amount, enough to power a 60-watt lightbulb for six months plus a forgotten open door refrigerator for a day.
