Academic Paper from the year 2006 in the subject Environmental Sciences, grade: 2, , language: English, abstract: This papers deals with the human effect of energy. As every process on earth relies on conversion of energy, maintaining human life and meeting the needs of mankind require energy as well. This demand has changed significantly in the period human beings are now occupying the planet. Millions of years ago the first humans basically used energy to maintain their elementary needs. This energy demand was satiated by chemical energy provided in the form of food. A human of these times generated 125 [W] only by muscle work. This was equal to his energy intake by food.
