potential energy
We run out of means to convert it. Coal is stored potential energy, if we use it all and the resulting heat energy escapes into space, we've lost that energy. World's water evaporates, no hydro power.
Depends on how big it is (button cell, car battery?) and on its chemical type.
The load in a torch is tehb thin tungsten wire in the bottom of the torch. It converts electrical energy into light energy.

powers the torch to give it energy
Yes, Normally a battery converts its chemical energy into light energy, and when the light falls upon an object some of its energy forms heat energy with some of the light energy "bouncing" back to yourn eyes. If you use a modern wind-up torch you, rather than the chemicals in a battery, are providing the kinetic energy from your own muscular power, and this becomes stored in a battery inside the torch.
NopeNo, potential energy would be, for instance, a spring that is compressed. It could cause motion if released. It is stored energy. The light bulb uses electrical energy, which it converts to light and heat energy. potential energy is like when you wind up a torch or a radio
Energy that is stored is called kinetic energy.
