15 Energy and the World

All of the activities of human beings depend on energy, as we realize when we consider the dimensions of the world's energy problem. The efficient production of food requires machines, fertilizer, and water, each using energy in a different way. Energy is vital to transportation, protection against the weather, and the manufacturing of all goods. An adequate long-term supply of energy is therefore essential for man's survival. The world energy problem has many dimensions: the increasing cost to acquire fuels as they become more scarce; the potential for global climate change resulting from burning fossil fuels; the effects on safety and health of the byproducts of energy consumption; the inequitable distribution of energy resources among regions and nations; and the discrepancies between current energy usage and human expectations throughout the world.
