The three energies involved are: spring, or elastic potential energy (EPE); gravitational potential energy (or GPE), and kinetic energy (KE). The energies are all changing in differnet ways depending on how much the spring is stretched and how high the object attached to the spring is. Note, however, that energy is conserved, the total energy stays the same (the bar on the right).

Alternate Energy Inc. Hawaii - Photovoltaic Solar Electric Solar Water Heating Honolulu Hawaii. The Energy Story - Chapter 1: Energy - What Is It? Energy causes things to happen around us. Look out the window. During the day, the sun gives out light and heat energy. At night, street lamps use electrical energy to light our way. When a car drives by, it is being powered by gasoline, a type of stored energy.
The food we eat contains energy. We learned the definition of energy in the introduction: "Energy Is the Ability to Do Work. " Energy can be found in a number of different forms. Stored and Moving Energy Energy makes everything happen and can be divided into two types: Stored energy is called potential energy. With a pencil, try this example to know the two types of energy. Put the pencil at the edge of the desk and push it off to the floor. Now, pick up the pencil and put it back on the desk.
How Do We Measure Energy? Energy is measured in many ways. One of the basic measuring blocks is called a Btu. Btu is the amount of heat energy it takes to raise the temperature of one pound of water by one degree Fahrenheit, at sea level. 1. Renewable & Non-Renewable Energy Sources. Alternative Energy - Wind, Solar, Hydro and other alt energy sources for home power.
