wouldnt a person just sent to jail also appeal aswell???
They might, but they don't tend to get the same latitude as a defendant waiting to be executed in terms of whether or not a court will even hear their appeals.
Google "cost of capital punishment," and you will find a number of links that present the studies in detail. Many are anti-captital punishment sites and so you should consider whether or not they have a bias. You will also find at least one pro-capital punishment site which disputes the claim that execution costs the state more than a life sentence.
It's an interesting question, but not one which, in my opinion, carries much weight in the debate.
Those who oppose capital punishment tend to argue that if execution is more costly than life imprisonment then their can be only one reason to execute, and that would be the deterrence effect (which they all then proceed to attack).
Of course this presupposes that societal retribution is not a valid reason for capital punishment, and that is a matter of opinion and nothing more.
The cost issue is an argument of convenience, as the opponents of capital punishment are not so fiscally conservative that if it were proved it was cheaper to to incinerate than incarcerate, they would withdraw their opposition.
As I've suggested before, society is always faced with choices about what action to take. Cost is a consideration but almost never the only consideration. It is quite costly to clean up hazardous waste sites. In many cases it would be much cheaper to leave them as they are and simply relocate the people who might live near them. This is only one example where financial costs are not the sole or primary consideration; there are many more.
Frankly, it would be a whole lot cheaper to simply execute someone convicted of a capital crime, within 24 hours of the sentence, but of course no one is arguing that course of action.
