Conservation of energy

Energy is defined as the capacity to do work. The English physicist Thomas Young (1773-1829) used the term energy (Ross, 2011). It is found in many forms like light, heat, atomic and subatomic behavior, etc. Energy can be converted from one form to another and the total energy in any closed system remains constant. In classical physics, this principle was known as conservation of energy; in modern physics, it is termed the conservation of mass and energy. Conservation of energy also has another meaning and that is to ‘save’ energy. As the natural energy sources become scarcer it is important to learn how to save energy. One way of doing this is to create an energy efficient home. To create an energy efficient home there are many measures that can be taken to save energy, they include: solar energy, as the sun is a constant natural energy resource we can store that energy and use it to heat out water. ‘Sleep mode’ on computers, computers are definitely becoming more and more popular in homes, if and only if the computer needs to be on at all times you should use the sleep mode which lets the computer run on the minimum amount if energy needed (Ross, 2011). Last but not least, energy can be conserved by doing the simple things around the home to lessen the usage of the machines that do work: example, turning applications off at the power point instead of just at the switch on the appliance and shutting all windows and doors and closing all curtains to keep the heat in the house instead of relying on the heater to do all the work, and vise-versa in the summer, to open all the windows and doors to let the cool air in instead of relying on the air conditioner. It is important for all people to realize the need for conserving energy. It is impossible for all the natural resources to keep up with our forever advancing civilization, and supply us with the energy that we need.
