Ultra-low cost and solar storm secured local DC electricity to address climate change challenges for all economies

Contrary to the outcome of the “history of war of currents”, the local generation of direct current (DC) power has the technical and economic advantages of emerging as the ultimate choice of power in the 21st century. Local DC power generated by photovoltaics (PV), batteries, electric vehicles (EVs), situational intelligence, intelligent loads, real-time monitoring of grid, cyber security, internet of things (IoT) and resiliency to space weather threats are the enabler of DC nanogrid and DC microgrid based ultra-low cost electricity infrastructure.
