It is difficult to come up with things that could not be improved by access to local, abundant and low cost or free energy considering how much of what we have in the developed world is energy dependent. Also, it is important to realize that much of the conflict and polarization there is in the world is due to control of and/or lack of energy resources. So almost all aspects of life would be improved.
There are so many people in the world who are still struggling to survive due to basic needs such as food, water, and shelter not being met. Some of these people live remotely and do not have access to electrical power that could help. ZPE based free energy could alleviate many of the issues they face and significantly improve their quality of life in a very short time.
In addition, much of the political strife and conflict we face today between peoples and nations has roots in trying to get or maintain resources. Free energy has the promise of eliminating this justification for conflict and war. In the same vein, access to energy is a tool often used to control or manipulate people within regions and nations. Availability of free energy sources could serve to bring people together and free them to manifest their best lives.
It is all tied to increasing our conscious connections and appreciation of our oneness.
So, a reasonable vision of a world with after the transition is one where we are no longer restricted and controlled due to lack of free and available energy. It is a world where most of the conflict between countries and cultures has eased or dissipated, where cooperation and communion are ubiquitous, where there is a general awareness and appreciation that we are all one as a species and that there are other species in the universe with whom we can co-create and manifest even more joy. In this transformed world, love forms the basis of our collective shared experience.
