Luck is one component, but you are more lucky if you have more land. EU population density is 112 people per square kilometer, US has 36 per square kilometer. EU area is 4.2 million square kilometers, US has more than double of that, with a smaller population. Also, low population density helps with extraction. A lot of the USA is desert where nobody is living so only few people will complain about fracking messing up their life.
