Why is USA pressuring Saudi oil production?

The USA has had thirty years to develop nuclear power and abandoned it due to liberal pressure and conservative weakness. The USA has oil resources but shrill voices on both sides are unable to find agreement on reasonable and environmentally clean increase in drilling. The USA has abundant coal but seems unable to commit to understanding what percentage of our energy should come from clean and safe processing of coal. Hydrogen and water, of course, have always been essentially "free" yet research in those areas are very late in starting. And of course elitist environmentalists view "green technology" as first and foremost the way to limit freedoms of other people and to line their own pockets with "green" and I don't mean vegetation. The USA has a lot of nerve to pressure Saudi to increase production of the ONE treasure that they have from God, which they must steward for their own people's needs into the future and not to enable the USA who has an abundance of resources and yet is so ungrateful to God and so handicapped in their ability to be wise stewards.
