What an interesting story! We will own a battery-powered car that gets us where we want to go, yet still serves to store solar energy for our evening use.
Does this assume that the electric car is left at home to charge all day? What is the expected life of these batteries?
There are so many assumptions made but then the story had limited space.
If it were all possible, the authors are telling us to go in debt — but the loans are affordable — to fit into their vision of Davis. Our vision is one where we stay out of debt, get out of town often and see the world.
Their vision argues that we will be self-sufficient through unspecified but not inexpensive investment, but that a Davis Utility Department (DUD) is necessary and that we buy out PG&E. If the vision really is the future, does anyone want to own any energy services company?
There are breakthrough technologies lurking that seem at least as likely to upend the electric utility business. We should concentrate on filling the financial holes we have already dug and stop digging any more.
