Electricity is generally defined as the ability to do work. It comes in various forms and types used in daily life, with electric energy being one of the most notable due to its ease of use and convertibility into other forms of energy. However, storing electric energy in large quantities remains challenging.
Electricity is utilized across a wide spectrum of applications: powering electrical appliances, heating homes, facilitating transportation, driving industrial processes, and serving numerous household and complex applications. Electric energy constitutes approximately 18% of the total energy types used globally.
Electricity originates from charged particles within atoms, creating electric fields that interact with other charged particles within that field. These interactions generate electrical forces that move the charged particles, resulting in work measured in energy units.
Electric energy is classified as a secondary source, not directly extracted from natural resources like coal but derived from primary sources such as coal, natural gas, nuclear energy, solar energy, wind energy, and others.

Storage of Electric Energy :
Electric energy storage involves several technologies aimed at retaining electricity for later use. These include rechargeable batteries, advanced energy storage systems like thermal storage, chemical storage such as hydrogen storage, hydroelectric dams, and mechanical storage systems like flywheels.
Storage of electric energy is critical for developing sustainable and stable energy infrastructure. It enhances sustainability in renewable energy systems like solar and wind by storing excess energy for use during high-demand periods or low-production times. Technologies used include large batteries, thermal storage systems, and hydrogen storage, contributing to energy sustainability and improving grid stability.
Applications of Electric Energy :
Electricity finds diverse and widespread applications, such as powering everyday electrical devices, personal electronics, and complex industrial systems like manufacturing machines and heavy equipment. This enhances productivity and improves production quality.
Moreover, electricity powers electric transport modes such as trains, electric buses, and electric vehicles, reducing greenhouse gas emissions and environmental pollution. It is also used for energy provision in workplaces and homes through electric heating, cooling, and lighting systems, thereby enhancing energy efficiency and reducing natural resource consumption.
Boiling Unit :
The boiling unit is a crucial process in chemistry and physics used to convert liquids into vapor. This process involves heating the liquid substance until it reaches its boiling point, where vapor continuously forms and escapes from the liquid surface. The boiling temperature is measured at standard pressure, with each liquid having a specific boiling point.
For instance, water boils at approximately 100 degrees Celsius under standard atmospheric pressure, making the boiling unit essential for various operations such as distillation, sterilization, preparing hot beverages, and cooking.
Electric Generators and Turbines :
Electric Generators:
An electric generator is a device that converts mechanical energy into electrical energy. It operates by rotating turbines or other moving parts powered by energy sources like water, air, or steam. The electric generator consists of magnetic coils and conductive coils that move synchronously to produce alternating current electricity.
Turbines:
Turbines are essential components in electricity generation, used in power stations to convert kinetic energy into rotational energy that drives electric generators. Types of turbines vary depending on the energy source used, such as steam turbines powered by steam produced from heat, water turbines utilizing flowing water for propulsion, and wind turbines used in wind power stations to convert wind energy into mechanical energy.
Use in Electricity Generation:
The use of turbines in electricity generation is a fundamental part of the global energy infrastructure, contributing to efficiently and sustainably generating large quantities of electricity. The technology used in turbines continues to evolve to enhance efficiency and reduce environmental impacts, thereby promoting the sustainability of energy sources and improving global energy systems.
