Disrupted Power – energy companies in a "death spiral"

From The Economist this week – the following quote is interesting:

What the industry needs is a new business model. The best prospect, thinks Elias Hinckley, an energy-finance specialist at Sullivan and Worcester, a law firm, is plug-in electric vehicles. Today, Americans’ daily spending on energy can be split into two large chunks: about $1 billion on electricity and $1.4 billion on fuel for their vehicles. In the past, electricity providers had no way to tap into the latter market. Plug-in cars should change that.
​Which is total rubbish – battery tech is advancing at such a rate that charging will probably only need to be once a month within 5 years.
