Our belief in an endless cornucopia of resources and wealth has also caused us to ignore care and efficiency in all of our institutional structures, production processes, and living patterns. The result is that they have developed almost inconceivable waste - which now represents an equally great opportunity for improved effectiveness and efficiency. They're due on the road in four to five years. Even greater magnitudes are possible in public transportation systems. It means homes that require only sunlight and rainfall to operate.
Prototypes are already in operation in almost all of our climate zones.
All these and more are immanent or already being implemented today. It is unlikely that we would ever follow such possibilities out to these extremes - if for no other reason that we decide we want to work more, or we want to do better for ourselves and all life, and ask for higher levels of performance in all we do. We've also looked at these issues very briefly and in isolation. In reality they are interactive. Some give resource savings but not financial or employment ones.
