"...when a feasible alternative to fossil fuels is better developed".

at some point there isn't going to be any more oil, and way before then it's going to get VERY expensive. much moreso than it is now. and alternatives will continue to be developed and become cheaper more efficient and more cost effective.

as for the economic good to the country/economy as a whole- as it's developed it will create jobs for engineers, installers, salespeople, factory workers, truckers, etc...and as those people earn and spend, it will create growth/jobs in other industries- retail, housing, etc.

that's the whole point of developing the technologies and the industry to the point that it CAN accomplish your points one and two, especially as the cost of fossil fuels goes up, and the availability goes down.
