Free electricity for electric cars
Here's a story about Meijers, a Michigan based retailer (a Wal-Mart type big-box store.)

They are putting in free electric car charging stations. One of these stores is just a couple of miles from me.
This is a great idea for retailers. Electricity for an hour of EV charging costs the retailer just a few cents. In exchange they get EV customers to shop at their stores.
As an EV driver, I get free electricity for my car in exchange for doing a little shopping, which I have to do anyway. In fact the availability of free electricity might encourage me to shop a little further away than I might ordinarily consider.
As an EV owner, I will definitely move almost all of my department store and grocery shopping to my local Meijers. (It's a great parking spot, too.)
So, market forces create a solution for EV charging stations. More stores, restaurants and hotels will certainly follow suit as EVs catch on.
