Document Summary
Energy-capturing technology refers to how people apply human labor and technology to natural resources. Features of the environment consist of sunlight, rainfall, soil quality, forests and mineral deposits. During the time of the earliest hominids, all the energy that was used came from food the first great step in the evolution of energy production was the creation of fire. 10,000 years ago, animals began to provide energy in the form of muscle power, harnessed first to sleds and then to plows and wheeled vehicles. Mastery of iron and steel had to precede the development of the mining machines that made feasible the large-scale use of coal, oil and gas. We would expect: fluctuations over time in the availability of resources. Activities of other groups in competition for these resources. Introduction of new technology that changes the way food is produced.
