What is Electrical Energy?
Electrical energy is the energy that is caused by moving electric charges. It is a form of kinetic energy that is generated when electrons move through a conductor, such as a wire. This movement of electrons can be harnessed to power various devices and systems.
How is Electrical Energy Generated?
Electrical energy can be generated through several methods, including:
- Chemical reactions, such as in batteries
- Mechanical energy, such as in hydroelectric power plants or wind turbines
- Thermal energy, such as in coal, natural gas, or nuclear power plants
- Solar energy, through photovoltaic cells
How is Electrical Energy Used?
Electrical energy is used in a wide variety of applications, including:
- Powering homes and buildings
- Operating electronic devices, such as computers, smartphones, and televisions
- Running appliances, like refrigerators, washing machines, and microwaves
- Powering transportation, such as electric cars and trains
- Operating industrial machinery and equipment

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
