What type of energy is at work when mini-blinds are being raised or lowered

The type of energy that is ar work when blinds are being raised or lowered is potential energy. because potential energy is the energy stored in an object due to its vertical position, the main cause of the potential energy is the acceleration due to gravity. so that is why its formual is PE = mgh

where m is the mass, g is the acceleration due to gravity and h is the height
