Energy is a crucial necessity and with the ever increasing need for it and the high and fluctuating prices of oil, researchers are constantly coming up with newer and more sophisticated alternative sources of energy. However, energy comes at a cost, as it is either expensive or it possesses high health risks. This essay presents the concept of energy by discussing the two major types of energy, the various forms it could take, including renewable sources of energy, energy conservation and above all it talks about the safest and cleanest alternatives.
Gottfried Leibniz first coined the term energy from the concept vis viva to refer to the square totality of an object’s mass and its speed, where total vis viva is stored. Energy is commonly defined as the capacity of a physical object or system to act on other objects or systems (Dean 8). The mass of an object determines its energy, which can be changed from one form to another. Since there is no universally stipulated determinant of energy, energy is expressed in comparative units for instance ergs and calories. The contemporary measurement of energy is the joule, which is its SI unit. Similarly, there are other acceptable, though larger units of expressing energy such as kilowatt hour and the British thermal unit.
There are two main types of energy: kinetic energy and potential energy. Kinetic energy is an object’s or system’s energy of motion, which is a product of its movement (Nardo, Shropshire and Young). It is the effort required to accelerate an object to a given speed and it is maintained by power fields and particles that have been subjected into a new physical setting in the field as a result of being acted on by another system. On the other hand, potential energy is a function of the position of an object. It is the work performed against a certain power during the transition of an object’s location with regard to a certain point of reference (Broyles 5). Other types of energy lie between kinetic and potential energy or are an amalgamation of both types.
There are no definite forms of energy since possibilities of new forms of energy are limitless. However, the various forms of energy in physical science include thermal, chemical, electric, radiant, nuclear, magnetic, elastic, sound, mechanical, and luminous energies (Foland 13). Thermal energy or heat is the energy in random motion of particles. Chemical energy refers to the energy from the aggregate of positioning of electrons and protons. Radiant energy is the energy of electromagnetic radiation while nuclear energy and electric potential energy is energy emanating from nuclear fission and electrical processes respectively. Sound is a form of mechanical vibration, which propagates through any mechanical medium. It is closely related to the ability of the human ear to perceive noise.
Clean sources of energy basically refer to those that do not encompass the burning of coal, petroleum or its products and the...
