**Energy Transformations in a Fossil Fuels Power Plant**

In a typical fossil fuel power plant, several energy transformations occur to convert the stored energy in fuels into electricity. These transformations are as follows:

1. **Chemical Energy to Thermal Energy**
   - Fossil fuels such as coal, oil, or natural gas contain stored chemical energy. When these fuels are burned in the power plant, the chemical energy is transformed into thermal energy, producing heat.

2. **Thermal Energy to Mechanical Energy**
   - The heat generated from burning fuels is used to boil water, producing steam. The thermal energy in the steam is then converted into mechanical energy as it expands and turns the blades of a turbine.

3. **Mechanical Energy to Electricity**
   - The spinning turbine is connected to a generator. As the turbine blades turn, the mechanical energy is transformed into electrical energy through electromagnetic induction in the generator. This process generates electricity, which is then transmitted through power lines for various uses.

These steps highlight the energy transformation process, from chemical energy in fossil fuels to the electrical energy we use in our daily lives. The options provided in the diagram are: chemical energy, electricity, mechanical energy, light energy, thermal energy, and kinetic energy.
