Next Generation Energy and Power -who Supplies It?

A great number of technical and social discussions are taking place surrounding the future of our energy needs, what our homes are evolving into, and how individual and work lifestyles must change to recognize the reality of ever-diminishing world energy (and other resources) supplies.
The average single home -75-76 million in U.S., 70%+ in viable temperate areas - has enough roof area and sun viable area to
a. Self sustain needed electricity for appliances, computers, household items.
b. Self sustain hot water for showering and perhaps heating using current methods.
c. Support readily available packages for environmentally viable combinations of heating/electrical power generation/recycling technology to be mostly self-sustaining.
Think of the economics of not having a power "grid" infrastructure. Or, if grid availability is important for safety and security reasons, having the ability to feed back excess power to the grid; or, store power generated during periods of minimal usage for later use.
We are only a generation away from "distributed work," the process in which centralized workplaces become obsolete. That said, having reliable communications infrastructure access becomes paramount.
A Distributed Work environment would contribute untold amounts of time and resource savings through reduced/eliminated commuting; reduced need for transportation infrastructure; and much more savings.
If the virtually omnipresent "home office" were really that, with the attendant communications and supporting infrastructure-group and individual video conferencing, multiple activity support structures, corporate "net" channels and structure as necessary-some estimates allow for up to 75% reduction in office space and centralized support structures. That is a complete turnaround from today's thinking about the workplace and infrastructure needed to support productive activity.
There are social interactivity and other considerations to be sure, but the benefits far outweigh the negatives.
Modern society and the energy needed to support it point ever more vigorously towards "smallest unit" independent design, meaning that the individual household could become the leaders in emerging technologies which could reduce the need for societal infrastructure by up to 75%!.Seventy five percent fewer roads means an equal reduction in individual transportation needs, mainly cars, and the equivalent reduction of 75% in diesel and gasoline usage, a savings over today's usage of more than 10 million barrels a day of imported oil!
To be sure, it won't happen overnight, but with appropriate consumer demand, within a generation or two. Imagine if your place of work was only 50 feet from your bedroom; if your ability to interact with most of your co-workers was supported by the video/audio/data capabilities we have even today! If we could stop building millions of acres of roadways and just use our existing roadway overheads for mass transportation infrastructure.
It might present more, not less, opportunities for interaction with friends and family, both near and far.
It could happen!
