In this chapter, we will take a look at the potential that technology offers for conserving energy use during our “daily life” activities in homes, offices and transportation. Later, in Chapter 7, we will look at these potentials again when we present the basic concepts of Vision 2050. Our proposal for Vision 2050 will take the year 1995 as our baseline year. Therefore, throughout this chapter, we will base our discussion on the state of technology in 1995. Where more recent data is available, we will examine whether we have succeeded in achieving greater efficiency in recent years.
