  3 Energy Resources, Supply, and Demand In this chapter, we will cover and examine one of the most fundamental aspects of energy application, in relation to the following elements: • Energy resources; • Energy Supply; and • Energy demand. Also, we see the relationships between the elements as well as their importance to our energy applications — as a which influences our worldwide energy application scenarios. 3.1 Introduction to Energy Resources, Supply, and Demand Our energy resources, Energy Supply, and energy demand can be represented by the optimistic, balanced plots shown in Figure 3.1. It is a general trend that, over the years, as total energy demand increases due to our daily energy requirements, total Energy Supply also increases in order to meet those demands. ∗ Y ear Total energy Energy resources Energy Supply Energy demand Figure 3.1 The interrelation of energy resources, Energy Supply, and energy demand based on optimistic, balanced total energy application (OBTE) scenarios. ∗ It is to be noted that the plot of total energy resources is also shown increasing year by year rather than as a fixed plateau; this does not violate the energy conservation laws as outlined in Chapter 1. The total amount of energy in the earth’s system remains unchanged, that is, theoretically, it is the total net available energy reserves that decrease with time (see Section 3.2.2). 79 80 Applied Energy: An Introduction 3.2 Energy Resources 3.2.1 What Is Energy Resources? Energy resources is a term used to define ways of getting energy for our energy applications. Our world’s energy resources basically have close links with the sun, which travels marvelously and consistently around the globe, as a result of which the sun also contributes useful rays and the associated energy on the earth.

  PART l 1 Global Energy Resources This Page Intentionally Left Blank 4 Energy Demand and Supply in the Global Economy WORLD UTILIZATION OF ENERGY The future global economy will be critically dependent on the continuing availability of reliable energy supplies. Energy in its mechanical, electrical, and thermal forms has been largely taken for granted in modern society. In industrialized nations, energy is readily available virtually everywhere and affordable by most citizens. Energy is also a universal requirement for business and industry as well as all other forms of human activity; almost every form of endeavor in modern times involves the direct or indirect use of energy in one form or another. Industry is heavily de- pendent upon electricity, heat, and gaseous and liquid fuels to support manufacture of products and provision of services. Any large-scale dis- ruption of energy supplies for extended periods can wreak havoc on business, communities, and the national economy. Energyusagehasincreased enormously since the IndustrialRevolu- tion, which introduced steam power and subsequent innovations such as the electric motor and the incandescent lamp. The advent of the gasoline- fueled automobile brought greatly increased demand for petroleum. A large, complex energy industry of coal mines, oil and natural gas wells, refineries, electric power plants, and pipelines developedaround the availability of fossil fuels and the technologies with which to convert them to practical application. Energy requirements are increasing at a steady pace in the industrial- ized countries. However, in the developing nations, energy demand is

  America’s economic success depends upon the development of domestic sources of energy from renew- able and nonrenewable sources. The plentiful supply of energy provides a region with a low-cost source of power attractive to companies and an opportunity to retain and attract high-wage manufacturing, distribu- tion, research and development, and service jobs connected to that Energy Supply. What Is Energy? Everything runs on energy. From people to machines, all devices on earth operate through the use of energy. Energy is either stored (poten- tial) or working (kinetic). Energy Supply comes in a variety of forms such as heat, light, motion, electrical, chemical, nuclear, and gravitational. 1 Nonrenewable fossil fuels of coal, natural gas, nuclear, and oil will remain the core of America’s Energy Supply; however, renewable sources such as wind, solar, hydropower, geothermal, and biomass are gaining a larger share as the nation’s energy source. The power sector will continue to rely on fossil fuel in the future, but its percentage of use will decline from 68 percent to 57 percent by 2035. Overall demand for energy in the United States is expected to slow down, based upon the population and demographic changes coming; how- ever, the industrial and commercial use of energy will remain strong. The global demand for energy will surge, particularly in emerging economies. Renewable and natural gas demand are expected to grow while demand for coal will drop in the United States and Europe but surge substantially in China, India, and other emerging markets. Supply of Energy Americans get their energy from a range of sources. However, the vast majority of the American Energy Supply comes from nonrenewable sources—primarily fossil fuels of oil, natural gas and coal.
