Energy is the ability to do work. Scientists define energy as the ability to do work. Modern civilization is possible because people have learned how to change energy from one form to another and then use it to do work. People use energy for a variety of things, such as to walk and bicycle, to move cars along roads and boats through water, to ...

Why Is Energy Important? Energy is essential for all life and all processes that occur across the entire universe. On Earth, the sun is the ultimate source of all energy that is available and used by people, animals, plants, and microorganisms.
Energy, in physics, the capacity for doing work. 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.

Clean energy is important because it has the power to enhance economic growth, support energy independence, and improve the health and well-being of the American people. The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) is committed to leading the nation’s transition to a clean energy economy for these ...
Nov 27, 2017 · In science, energy is the ability to do work or heat objects. It is a scalar physical quantity, which means it has magnitude, but no direction. Energy is conserved, which means it can change from one form to another, but isn’t created or destroyed.
Why is Clean Energy Important? Our world runs on the energy we produce. Clean energy production allows us to generate the energy we need without the greenhouse gas emissions and negative environmental effects that come with fossil fuels, in turn helping to reduce climate change.
