That is completely impossible. Maybe profit, but not revenue. Even my sedan with a 17 gallon tank costs more to fill up than even a pack-a-day smoker with a lottery addiction and a love of energy drinks is likely to spend at the shop.
Typically a gas station makes 1 or two cents per liter. A 17 gallon tank is approximately 68 liters so that's between $.68 and $1.36 or thereabouts in gross margin for the station. Of that they still have to operate and service the pumps, and deal with periodic mandatory environmental upgrades and inspections.
You have to do millions of liters per year to turn a profit on the gas. Gross profits on store goodies are on the order or 20 to 30%. If they're refrigerated then likely it is on the low end, if they are non-perishables then it is on the high end.
Though if these stations charge using solar power and store the power in a battery pack to discharge when a car hooks up, it could potentially cost them a lot less than $0.11/kWh, depending on the cost of building the station itself.
Also add maintenance of all those batteries and I bet you'd have a really hard time to motivate solar for economical reasons.
So currently you do not have to worry about batteries or storage. You only have to worry about producing on average about as much as you use. The electric company does not have to worry about storage either because times of high sunshine always coincide with times of high electricity demand (due to air-conditioning).
So currently one can easily install and use solar without ever worrying about batteries or storage. If we ever get to the point where we rely exclusively on solar and wind, we will have to start worrying about storage, but this point is far off for now. Also, at that point the responsibility for storage will likely fall on the electric companies.
The argument about 'free solar' is almost an oxymoron. That electricity costs more per kwh than most any other source.
Tesla is attacking every single anti-EV argument in a very deliberate way and most of the attacks are strong successes.
And there is also a strong argument that the manufacturing and installation costs of solar farms has a long payback. They are a battery in that sense - energy invested in them slowly comes back out. PRobably petro-energy. So intially solar is a net negative in eco-impact. Same with wind.
1 billion kw-h / day more is a nice big tick on that, but I'm not sure it would drive prices a whole lot.

It takes about $0.20 to refine a gallon of gas, so ~2kWh/gal. Except, It obviously actually takes less electricity than that, because there are other costs to refining. Not a bad investment in energy terms, when a gallon of gasoline contains ~36.6kWh worth of energy.
But at the most this is change in the revenue model for 'gas/electric' stations or whatever you would like to call it.
But at the present and things as they stay, no body is likely to compete with Tesla. They are only having this network so as to ensure people can roam around without having to worry about running out of fuel. Tesla itself may not offer free energy once their user base grows to a substantial amount.
This is a incentive to get users to buys their cars, not a free energy give away drive. Once they have substantial customer base, free market dynamics will take care of the energy supply.
It must be the other way around. If you want free power, design your car to use their connector standards.
If I were running Tesla, I'd let my competitors' cars come and charge at the station, then sell them lunch and snacks.
Its not like they will be forced to buy whatever is in these stops - but the fact that the consumer can now actually CHOOSE what to spend those funds on is wonderful.
I HATE BUYING GAS
I currently don't drive at all (I bike to bart and bart to work) - and my car had its starter go out, so I haven't even been inside a car in more than a month.
I have always hated buying gas - I feel like I am being extorted every single time (and yes, I still harbor a grudge against bush/cheney whom I feel is largely responsible for this situation - whether this is unfounded blame or not, I still feel good about it :) )
