Money and Energy (The Solar Shed Example)

The study of physics can be brought into the perspective of everyday life using the example of the solar shed. This certainly involves the concepts of energy and materials as well as space and time. A site survey is a necessity to decide how where to place the shed. There are ways to predict the amount of sunshine to expect from a site. The design of the shed, especially the roof lines can be a factor in the construction of the device. Will the shed be constructed to store energy or will it be used to supplement the energy needs of a household? Energy and money are similar in that one is the basic media for transactions in nature and the other the basic one for transactions in a society. If one begins a study of physics through the study of energy, one can learn quite a lot Sunlight is a form of electromagnetic energy. Electricity and heat are other forms of energy. Plants and trees as well as the lawn itself store the energy of sunlight. The shed can use a battery or fuel cell to store sunshine. The concept of conservation of energy has been an important one in the study of both classical and modern physics. One can proceed to determine the return on the investment of a solar shed.
