At once, all around the world, there are 2,000 thunderstorms occurrence, producing over a 100 lightning strikes a second. That's in excess of 8 million lightning bolts each day unleashing the power of 2 million tons of TNT. Other than how do clouds come by all this energy, and couldn't we put it to good use?
Scientists started to suppose that lightning must be a form of electricity as shortly as the 1700s because it looked close to the sparks you could produce by rubbing certain materials jointly. Scottish scientist Robert Symmer had this off to a very well art and earned the dubious title of "the barefoot philosopher" since he was always removing his silk socks and rubbing them on things to generate sparks.

But it was a bold experiment by Benjamin Franklin in 1752, and one which he was blessed to survive, that bearded out it one time and for all. Franklin flew a kite into a thundercloud and was returned with a stream of sparks curving from the bottom of the kite string.

So how much energy is waiting up there?
Every lightning flash is as regards 3 miles long but only with reference to a centimeter broad. It discharges about 1-10 billion joules of energy and generates a current of some 30,000 - 50,000 amps, which heats the surrounding air to over 20,000 degrees Celsius, three times hotter than the surface of the sun (6000 degrees Celsius). Actually a single lightning bolt unleashes as greatly energy as blowing up a ton of TNT. And even though it might appear a single flash, a strike is in fact made up of between three and twelve individual lightning 'strokes', every lasting only a few thousandths of a second. This is what makes lightning show to flicker.
About thunder
The intense heat of the lightning discharge superheats the nearby air causing it to expand volatility. This makes a compression or 'shock' wave - the thunder - which extensive through the air in all directions, travelling at about a fifth of a mile per second. The flash and the thunder clap are formed simultaneously - as anyone unlucky sufficient to have ever got very close to a lightning hit can tell you - but the light from the flash travels a lot more quickly (186,000 miles per second) than sound (0.2 miles per second approximately). The light consequently reaches you first, then a short while later (depending upon how far away the storm is), the thunder rolls in.
