noun.
The capacity of a system to do work. It can exist in various forms such as heat, light, electricity, chemical, and nuclear, and can participate in different processes.
Origin
The word "energy" is derived from the French word énergie. This word comes from the Latin energia and the Greek energeia (the power of doing work, activity). The concept of energy has been addressed in various scientific fields since Ancient Greece, and it became a major concept, particularly in the fields of physics and engineering, during the 17th and 18th centuries.
Areas of Use
• Historical Use: The concept of energy gained significant momentum in the 19th century, particularly with the invention of the steam engine by James Watt. Afterward, energy sources began to play a major role in production processes and industry.
• Modern Use: Today, energy is a vital resource for electricity generation, transportation, industry, and domestic use. Additionally, investments in renewable energy sources have become a growing priority for developing environmentally friendly solutions.
Use in Different Fields
• Physics: Energy is a concept related to the various states and movements of matter. Different types of energy, such as potential, kinetic, thermal, electrical, and nuclear energy, form the foundation of physical processes.
• Industry and Manufacturing: Energy plays a critical role in manufacturing processes, machine operation, and heating-cooling systems in factories. Furthermore, energy efficiency has become an important goal for sustainable production processes.
• Transportation: Vehicles, airplanes, ships, and other modes of transport rely on energy sources to operate. Different types of energy, such as fossil fuels, electricity, and hybrid systems, are used to improve efficiency in transportation.
