The Earth s Journey With Energy - 1448 Words

It has been said, that the only constant pursuit of humanity since the dawn of man is the continuous accumulation of knowledge. For thousands of years humans, as engineers, have been harnessing and manipulating many forms of energy. As humanity gained knowledge, they became better able to manipulate energy into a productive force. The harnessing of fire, steam, oil and nuclear power have all greatly influenced humanity. The first monumental leap in mankind’s journey with energy, was when early hominids mastered fire around 350 000 years ago.[1] The knowledge of fire making largely attributed to the evolution of humans. This is in result of cooking meat with fire. This simple practice had a enormous impact on how some early hominid species evolved into humans. When meat is cooked, it becomes significantly easier to consume, as well as digest. Observations of chimpanzees today, show a common practice among the species in the method in which they consume raw meat. When eating raw meat, chimpanzees will combine portions of meat and tree leaves in their mouths to facilitate chewing and swallowing. The leaves provide traction for the slippery and rubbery raw muscle while chewing. This helps the chimpanzees spend less energy consuming the food, and increases their net caloric intake for the meal. When eating cooked meat, this net caloric intake is much higher than chimpanzees, since chewing the cooked meat alone is even easier than combining it with tree leaves [2].

The core, the convection zone, and the photosphere are four main layers of the sun. The core makes energy from hydrogen for the world’s sight (Elvis 12). About 99 percent of the energy generated by the sun through nuclear fusion is produced in its core (Koehler 14). Photons transport energy generated in the sun’s core. This m ovement from the sun’s core is not instant, in fact, it can take up to 150,000 years for energy to reach the photosphere.
