1. Dictionary Definition: Is a resource primary or secondary which allows for work or serve as alternative economic activities independent of energy production. ENERGY TYPES OF ENERGY Energy Basics Energy Calculator Energy Units Basics Forms of Energy Periodic Table Kilowatt-hours to mega joules, short tons to metric tons ,this handy calculator converts from one energy unit to another. The different rows of elements are called periods. The period number of an element signifies the highest energy level an electron in that element occupies. Is in everything. We use energy for everything we do, the food you eat contains chemical energy, There are two types of energy: Energy forms are either potential or kinetic. Potential energy comes in forms that are stored including — chemical, gravitational, mechanical, and nuclear. Physical units reflect measures of distances, areas, volumes, heights, weights, mass, force, and energy. Different types of energy are measured by different physical units:

2. UNITS: TYPES TYPES Barrels Stored (potential) energy Working (kinetic) energy KineticEnergy PotentialEnergy Cubic feet for natural gas IS IS Tons for coal Example Kilowatthours for electricity Is stored energy and the energy of position — gravitational energy. There are several forms of potential energy. Is motion — of waves, molecules, objects, substances, and objects. The food you eat contains chemical energy, and your body stores this energy until you use it when you work or play. To compare different fuels, we need to convert the measurements to the same units.

3. TYPES.. TYPES.. ENERGY SORURCES Chemical: Is energy stored in the bonds of atoms and molecules. Radiant: Is electromagnetic energy that travels in transverse waves Energy sources are divided into two groups. Mechanical: Is energy stored in objects by tension. Thermal: Or heat, is the vibration and movement of the atoms and molecules within substances Renewable Nonrenowable Nuclear: Is energy stored in the nucleus of an atom — the energy that holds the nucleus together. Coal Solar Motion Energy: Is energy stored in the movement of objects. Natural gas wind Gravitational: Is energy stored in an object's height. Oil Geothermal Sound: Is the movement of energy through substances in longitudinal waves Fossil fuels Biomass Electrical: Is what is stored in a battery, and can be used to power a cell phone or start a car.
