A windmill’s blades move from the blowing wind. The movement of the blades represents KINETIC energy.

The visible light that allows people to see where they are going describes RADIANT energy.

a) Energy can be categorised into two types: Kinetic and potential

Kinetic energy is the energy associated with motion or movement of any system

Potential energy is the energy stored in a system

Thus, a windmills blades move form the blowing wind, the movement of the blades represent Kinetic energy

b) Visible light falls in the electromagnetic spectrum and is composed of photons or particles of light that have a characteristic wavelength and frequency. Thus, visible light that allows people to see where they are going describes electromagnetic energy (kinetic energy).
