It is too bad the understanding of most people in regards to energy generation, distribution, and use remains in the last century with little understanding of where things can and need to go.
Distributed generation and storage will evolve to much more reliable and inexpensive systems that we have been used to.  The concept of storage should not just be thought of as just batteries, for instance.  We have had grid storage in nuclear systems that run best at relatively constant output.  Pumped water storage was economical then as it is now. Thermal mass and phase change storage allows electric use at none peak times with making ice at night. Other forms of storage can be seen in phase change crystals in drywall. We will likely see a lot of grid stage as hydrogen which may be converted to things like ethanol for more convenient use in transportation.
HVDC lines are planned for moving energy from one part of the country to another.
