Energy

Energy is the ability to do work. There are many different types of energy including kinetic, potential, thermal, electromagnetic, chemical, nuclear, and mass. All natural phenomena have been defined by these different types of energy. The basic scientific principle of energy is that it can neither be created, nor destroyed, only converted from one form to another.

Energy in this day in age is a very important topic. Managing and controlling energy is essential to an industrialized world. It is needed for agriculture, communication, technology, and transportation. Toady energy and energy resources are used synonymously. Energy resources include fuels, petroleum, and electricity.

Today, however, the world's increase in the use of energy has some negative effects. These effects could potentially have serious effects on our world. Such problems include global warming.
