Heat.
The motion of air in the troposphere is governed by heat from the surface of the Earth.
We all know that warm air rises. When the temperature profile of the troposphere is such that, when a parcel of air is displaced upwards, it continues to rise because it is less dense than the air around it, then you have an unstable atmosphere. This is what creates clouds and thunderstorms.

"Thunderstorm
From Wikipedia, the free encyclopedia
.A thunderstorm, also called an electrical storm, is a form of weather characterized by the presence of lightning and its attendant thunder produced from a cumulonimbus cloud.[1] Thunderstorms are usually accompanied by heavy rainfall and they can also be accompanied by strong winds, hail and tornadoes. In the winter months, snowfall can occasionally take place in a thunderstorm. Such is often termed thundersnow.
Thunderstorms form when significant condensation—resulting in the production of a wide range of water droplets and ice crystals—occurs in an atmosphere that is unstable and supports deep, rapid upward motion. This often occurs in the presence of three conditions: sufficient moisture accumulated in the lower atmosphere, reflected by high temperatures; a significant fall in air temperature with increasing height, known as a steep adiabatic lapse rate; and a force such as mechanical convergence along a cold front to focus the lift.[2] The process to initiate vertical lifting can be caused by (1) unequal warming of the surface of the Earth, (2) orographic lifting due to topographic obstruction of air flow, and (3) dynamic lifting because of the presence of a frontal zone.[3]
Thunderstorms have had a lasting and powerful influence on early civilizations. Romans thought them to be battles waged by Jupiter, who hurled lightning bolts forged by Vulcan. Thunderstorms were associated with the Thunderbirds, held by Native Americans to be a servant of the Great Spirit. [citation needed]
According to Encyclopedia Britannica, if the quantity of water that is condensed in and subsequently precipitated from a cloud is known, then the total energy of a thunderstorm can be calculated. In an average thunderstorm, the energy released amounts to about 10,000,000 kilowatt-hours (3.6 x 1013 Joule), which is equivalent to a 20-kiloton nuclear warhead. A large, severe thunderstorm might be 10 to 100 times more energetic."

when air get warm by sun light it get heated and due to low density becaue of heating, this air move upward and the cold air come down to fill the place of moving air.. this is couse for high speed wind blowing and then if the wind flow at very high speed, the particles of cloud strikes with each other and get over charged.. and these +vely charged partilcles get attracted towar earth as eart is -ve charged.. and high voltage fall on earth.. and all these causes creat thunderstom by combining each other

The main source of energy in a thunderstorm is latent heat relesed when water vapour condenses into water droplets and water droplets freeze into ice crystals.
