and who share electricity generation, transmission, and storage infrastructure in smaller, more decentralized, more autonomous, and community-owned non-profit networks-- which use newer, better, and cheaper micro-grids and nano-grids, and ever-improving capabilities and declining costs of ever-more decentralized small-scale generation and storage techs--to mimimize their vulnerability to the greater risk, inherent in a more traditional centralized grid, of system-wide failure, due to:

acts of nature, or 

routine and/or extraordinary technical operational problems, and/or 

intentional system-wide disruption (by hackers, terrorists, criminals, and/or hostile foreign government entities) 

while also reducing their energy costs as much as possible by eliminating the need to generate a guaranteed profit for HEI shareholders and executives, forever and ever, Amen ;)
