The electrical industry may be using SI units, but the fact that the units are a part of SI is unknown to the public. In the public mind the units of electricity are as English as the foot and the pound. Thus there is no resistance to their use.

They are here now! The electricity infrastructure is in place but needs to be strengthened. There is no H2 infrastructure in place and it would be expensive to build to make it as convenient as electrical outlets which are everywhere. Solar panels on roofs of homes and buildings will provide a distributed energy system. MI State U has developed flexible shingles but they need to be printed on flexible material 1 m x up to 5 m to make them economically practical. Wind turbine electricity generation has proven to be practical. They can be built now if elected officials would get out of the way and let them be built where the wind is such as along the northeast cost of the US and on mountain tops like some are doing in ski areas. Battery development is in its infancy. Elected officials are the impediment. The SI is used in the electricity industry now; however, its use needs to be refined.
