They build up.
Lightning is a sudden discharge of electrons from clouds to the ground. When storm clouds gather up lots of electrons, which are negative, the electrons are attracted to the ground's positive charge (opposites attract). The cloud's electrons build up so much that they leap to the ground in one stream, causing visible lightning.

A positive or negative electric charge can build up on a material's surface through the gain or loss of electrons. This can occur through processes such as friction, induction, or conduction, where electrons are transferred between materials, resulting in an accumulation of charge.
Usually static electricity is caused by a build up of electrons on the surface of an object

Static electricity is a build up of electrons. Static means still or stationary. Electrons on metal can not be stationary as the metal is such a good conductor of electricity. To remove static electricity after dragging your feet on a nylon carpet just touch a metal appliance or pipe eg a tap. Wood is generally porous so electrons again do not build up but ebony will build a static charge as it is a very dense wood. Electrons build up on plastic as it is a poor conductor. The electrons are static and a charge builds. Static electricity is caused by electrons being knocked off or building up on objects that are not normally good conductors.
Static electricity can build up on an object when there is an imbalance of positive and negative charges on its surface. This can be caused by friction between two objects, where one object gains electrons and becomes negatively charged while the other loses electrons and becomes positively charged. When the two objects separate, one object retains the excess electrons, creating the build-up of static electricity.
Electrons build up electrical discharge. They carry negative charge.
The electricity caused by friction is known as static electricity. It occurs when two objects rub against each other and transfer electrons, creating a build-up of electric charge on their surfaces.
In a capacitor it is a build up of electrons on a plate.
A conductor can build up a static charge by gaining or losing electrons through friction with another material. This excess or deficit of electrons creates an imbalance in charge, leading to a build-up of static electricity on the surface of the conductor.
Voltage is a build up of electrons at one location relative to another location. To form a voltage gradient (difference), you need to somehow build up electrons at one location, or remove electrons from one location. Shuffling your feet on a thick carpet can do this!
Sparks! And when the distance is large enough, lightning!
Coronary Heart disease caused by atherosclerosis or the build-up of plaque on the inner walls of the arteries.
Electricity is created by the movement of electrons in a particular direction. A large jump of electrons results in sparks, or even lightning.
