The correct type of energy that includes hydraulic and electrical sources is potential energy. Potential energy refers to energy that is stored in an object due to its position or state. For example, hydraulic energy is stored energy in pressurized fluids, and electrical energy can also be seen as stored energy in the form of electric potential due to voltage differences.
Hydraulic energy relies on the potential energy of water or other fluids that are elevated or pressurized. Similarly, electrical energy has a form of potential energy where electrons are positioned in a way that allows them to do work when released from their potential state.
In contrast to other options, stored energy and hazardous energy do not specifically refer to the forms of energy mentioned in this context. Stored energy is a broad term, while hazardous energy typically relates to energy that poses a safety risk, such as the energy in the moving parts of machinery. Static energy refers to the energy related to electric charges that are not in motion, which does not accurately encompass the dynamic nature of hydraulic and electrical sources.
