Energy is a fundamental concept in science, representing the capacity to do work or produce change. It exists in many forms—including kinetic, potential, thermal, chemical, and nuclear—and powers everything from the tiniest atomic interactions to the largest cosmic events. In physics and engineering, energy is conserved and transformed, while in fields like biology and environmental science, it’s essential for sustaining life and driving ecological systems. This page features the latest research on how energy is generated, transferred, stored, and harnessed—spanning innovations in renewable energy, cutting-edge materials, and the physics that underlie it all.
