The main energy conversion is from chemical energy stored in the battery to electrical energy. The electrical energy powers the light bulb to produce light and heat energy.
When a match is lit, chemical energy stored in the match head is converted to thermal energy through combustion. The thermal energy then ignites the wood in the match, producing light energy and more thermal energy due to the flame.
In a torch, electrical energy from the battery is transformed into light energy and heat energy by the bulb and may also produce a small amount of sound energy.
A clothes dryer converts electrical energy into heat energy to dry wet clothes. The heat energy evaporates the moisture in the clothes, which is then expelled from the dryer as steam.
When you light a candle, the chemical energy stored in the wax is converted into heat and light energy through a combustion process. The heat generated melts the wax, which is then drawn up the wick where it vaporizes and burns, producing both light and more heat.
The electrical potential energy of an electron leaving the negative terminal of a 1.5V battery would be 1.5 electronvolts (eV). This energy is gained by the electron as it moves through the circuit towards the positive terminal.
The energy in a battery is stored as chemical energy. When taking the energy out of the battery, it is of course converted to electrical energy.
When a match is lit, chemical energy stored in the match head is converted to thermal energy through combustion. The thermal energy then ignites the wood in the match, producing light energy and more thermal energy due to the flame.
Taking energy out of it, i.e. using it to run stuff.

That will vary widely from one country to another; it also varies with time. In some countries, a lot of energy is used for heating. Where heating isn't used, both lighting (light bulbs) and taking showers uses a lot of energy. In houses with solar homes, there is no recurring cost for taking showers (technically it still uses energy, but it doesn't get on the power company's bill), so in that case, lighting is probably the biggest consumer.
The battery charger in a computer works by taking the electrical current in the socket and using that energy while the computer isn't plugged into the socket.

In most cases, chemical energy stored in the battery produces the electric current. Rechargeable batteries are capable of taking electric currents and using them to reverse the chemical reactions, thus gaining more chemical energy that can be used readily.
Photoflex Lighting School, is a division of Photoflex Lighting in Watsonville, California, on the Monterey Bay. At the Photoflex Lighting School, one can learn the art of lighting for photography

You put the battery back in and you charge it
