    Turning on a light switch

    Explanation:

    According to the first law of thermodynamics, the energy can neither be created nor be destroyed. Hence, it can only be transferred from one to another.

    Thus, in the option solar panels at work, the solar energy is transformed into the electrical energy and in the option formation of static electricity the process of transformation of the mechanical or chemical energy into electrical energy is taking place.

    While turning on switch is just an task that does not involve transformation of energy. It just completes the circuit to allow the flow of current.

    Hence, the answer is option "Turning on a light switch"
