Electricity Generation Concepts

Electricity is generated by converting other forms of energy. Chemical energy from burning fuel is transformed into thermal energy, which heats water to create kinetic energy. This kinetic energy turns a turbine connected to a generator, converting it into electrical energy. The generator's wire, surrounded by magnets, causes electrons to move, creating an alternating current similar to what is used in homes and schools.

What type of energy is created when coal is burned to generate electricity?

• Nuclear energy
