Energy is defined as the ability to do work, such as propel the body forward by taking a step (motion). Energy and its ability to do work are measured in joules: power (watts) x time (seconds) and work joules = force (newtons) x distance (Trefil et al, 2010). Energy exists in many forms; kinetic (motion or movement), potential (stored), thermal/heat (atoms and molecules), wave and mass (Trefil et al, 2010) to name a few. Energy is interchangeable, thus it can be changed from one form to another. Where might all of this energy come from? All living systems and/or organisms are sustained through a process call photosynthesis which harnesses energy from the Sun for the purpose of providing dietary sustenance to the inhabitants of the Earth. Conversely, the Sun supplies the radiation necessary to heat and light the Earth, which is beneficial to all living systems and/or organisms. Hence, the Sun is the origin of energy. The focus of my essay will be to explore the current ways in which we use the Sun’s energy to supply heat and light on Earth, the advantages and disadvantages of our current energy methods and/or sources, and ways in which we can utilize renewable energy sources and reduce and conserve our current energy consumption.…
