To process the natural gas and to lift them involves huge resources and enormous risks since it is difficult to transport natural gas and very risky to handle them since they are highly inflammable and also there is the risk of protecting pipelines that run through across continents.
With nuclear power yuo can have underground reactors and less risk since this can be based in underpopulated regions.The US has the technology to do make this possible.Only a bloody biased fool will not see the ecnomic benifits of this .This fools are all communists who bloddy well dont want our country to develop.
