Understanding the Context

It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or various other forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. Learn more about energy in this article. Scientists define energy as the ability to do work.

Key Insights

Modern civilization is possible because people have learned how to change energy from one form to another and then use it to do work. Energy is one of those words everyone uses and almost nobody can define precisely. Ask someone what energy is and you'll hear "the ability to do work" — which is circular, because work is defined in terms of energy. Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the capacity to do work and in the form of heat and light.

Final Thoughts

DOE published the Fusion Science and Technology Roadmap to Accelerate Commercial Fusion Power. DOE is investing $350 Million to strengthen coal-based generation, grid reliability, and strategic energy infrastructure. The value of energy trade between the United States and Canada fell by 11% in 2025 to an estimated $137 billion, according to data from the U.S. Census Bureau. Energy trade value is the total value of energy imports and exports between two countries and is driven by commodity volumes and prices.
