They explore the changing patterns of supply and demand, offer insights into the forces that are driving the changes, and discuss energy planning strategies that take advantage of such insights. The book addresses several major issues, including the growing vulnerabilities in the U.S. energy system, the influence of technological change, and the role of electricity in meeting social objectives. The strongest of the book’s themes is the growing influence of environmental concerns on the global energy system.
