What is the electric drill useful and non-useful energy?

An electric drill is primarily useful for converting electrical energy into mechanical energy to perform tasks like drilling holes and driving screws. This conversion allows for efficient operation, making tasks quicker and easier. However, non-useful energy may manifest as heat generated during operation, which can lead to energy loss and potential overheating if not managed properly. Additionally, noise produced during drilling can also be considered a non-useful byproduct.
