Energy Essay

Over the past decades, geologists and scientists alike have determined that the Earth is running out of non-renewable resources, particularly those resources that provide us with energy that fuels our world’s economies, jobs, and most importantly our daily lives. Without this energy, whole countries can collapse, and the human race would struggle to survive. Therefore, it is safe to assume that we as a nation are entirely dependent on energy, or the ability to do work (Gale Science in Context). Consequently, we are now actively searching for more cost efficient and useful forms of energy to replace those we currently use. By doing this we will be helping the earth by reducing carbon emissions and cutting down on air and water pollutants. This may ultimately prolong the life of our planet, and save money and resources while doing so.
While the quest to find the best sources of energy may not necessarily be an easy one, there are many forms of energy to consider when determining the type that would make the most sense to make use of based on our goals and parameters (such as finding a cost effective source that will be beneficial to the environment). As briefly mentioned above, energy is the ability to do work, and it can be observed in many forms throughout the universe. Each form of energy has unique characteristics, as well as a certain impact on our lives. Various forms of energy include chemical energy, electrical energy, light energy, nuclear energy, sound energy, and thermal energy. Though each of these forms of energy has unique properties, properties, and uses and therefore work together to help to power the world we live in. Chemical energy can be described as the energy released when substances undergo chemical reactions, and it is often used in important energy conversions, such as changing the chemical energy in coal in to thermal energy (which can be described as energy that is the result of the random free movement of particles), which then transforms in to electrical energy (the energy found in active electrons) that powers our homes, schools, and workplaces. Due to the result of chemical reactions that take place when substances and objects undergo chemical change ,and considering that the production of light and thermal energy (the energy of a substance relating to its temperature, or the energy of moving and vibrating particles of matter) is often a sign of chemical change, light energy, which is simply defined as the physical manifestation of the energy exhibited and produced by electromagnetic particles, can be considered related to chemical energy (which is defined above). A fair amount of our light energy comes from the sun, and this energy travels in waves, much like sound energy which is produced by the rapid vibrations of particles. Another form of energy that is very useful, especially since we as a nation are currently running out of natural resources is nuclear energy which is cultivated as a result of the energy...
