How Energy Is Produced

Energy, in basic physics, is the capacity for performing work or achieving work through motion. In common usage, energy is usually used to describe a product or material that is not defined as an element by another science, such as chemistry. In physics, energy can be defined as the power that forces do in motion. It can exist in different forms, depending upon the subject or application.


One example is sound energy, which is energy that is created through sound vibrations. A cricket struck in the upper chamber of a car will generate a whirling sound, while a plane flying eastward will create a jet stream with sound and energy. The source of this kinetic energy paves the way for a chemical reaction between the two molecules. Energy can also be converted from one form to another. Thus, we have converted from a substance (in this case, water) to a gas (in the case of gaseous fuels).

A second example of energy is light energy, which is the potential energy transferred between objects due to their position and time. Heat energy is the only form of energy that is not caused by any kind of chemical reaction. It is similar to light, except that it is not emitted because of some chemical reaction. Potential energy is measured by wattage, which is a unit of power measured by kilograms per hour. If a tennis ball hits a wall, the amount of energy it contains is the square root of the velocity it was going to when it hit the wall, times the square root of the time it took to go from point A to point B. While kinetic energy is simply the ability to move something, potential energy is the ability to add that thing to the force that acts upon it.

Energy System

The third example of energy is the international system of energy, which is defined as the totality of the force of the planets and stars behind the earth. This force is so great that if the sun is exploded, all the other elements in the solar system will still continue to move with it. Because of this huge amount of energy, we can determine that the sun holds more energy than all the planet’s neutrons, protons, and electrons combined.

All three types of energy have their own characteristics. Kinetic energy cannot be destroyed, so it is a great source of renewable energy. Chemical energy is one of the forces that cannot be destroyed, which makes it a great form of energy as well. And the last type of energy, which is the total of the different forms of heat energy, is what determines the temperature of the Earth. The Earth’s temperature is controlled by variations in the sun’s radiation, which are also a form of inherent potential energy.


Each one of these forms of energy has their own characteristics, and their uses. Kinetic energy, for example, can be converted into mechanical energy, which can be used to turn a turbine. In chemical energy, things like electricity can be produced from heat or converted into kinetic energy. And, of course, thermal energy can be produced from the heat of the sun or from the heat of a person walking across the surface of the ocean. These five different forms of energy have an overall effect on how we use our energy, and how the planet uses it.
