Taking a lead from the utility market, where OPower uses data from utilities to let consumers know how their energy use stacks up against comparable households, the car companies could let customers know how their fuel efficiency compares with other owners of the same type of vehicle, then suggest ways to improve.
The inability of the market mechanism to achieve a higher efficiency value is due, in part, to the incentive U-Type bidders have to strategically reduce their demands for the second block of spectrum.
Since utilities are in the business of generating and distributing energy and not saving it, most of the energy efficiency work in California has been outsourced to companies that specialize in that type of work.
The unit experiments like mad on everything from how to type tax collection letters in order to maximize participation to how to improve energy efficiency.
