An example each of the following energy transformations is as follows:
- Light energy into chemical energy: When light falls plants and trees, its energy is converted directly to chemical energy.
- Chemical energy into heat: combustion including fire, oxygen reacts with a fuel creating products of lower chemical energy with the difference going into heat.
- Chemical energy into electrical energy: Batteries and cells can change chemical energy to electrical energy.
- Mechanical energy into electrical energy: Hydroelectric power plants use the flow of the water and generate electricity with it.
- Thermal energy into electrical energy: Thermal power stations use thermal energy by heating coals and converting them into electricity.
- Light energy into electrical energy: Bulbs convert the light energy to electrical energy.
