Oil is cheap, not sure why it needs to be lowered. It's at or below the inflation rate for the last 40 or 50 years. Your taxes in CA are high, not the gasoline.
You bring up the costs for national defense all the time when it comes to oil. Makes no sense at all.
It's all speculation forgetting about here the oil we export. Forgetting about alternative energy sources to generate electricity to charge electric cars and related costs. Forgetting about the rare elements we need to make BEV batteries of which our arch enemy China controls. You do know the war they are conducting against us on that right?
Forgetting about every device in your home contains materials made from oil. (Only 19 gallons of a 42 barrel of oil is used for gasoline) Meanwhile ignoring the massive costs to the US consumer to switch to BEVs. Who is going to pay for the power and grid upgrades if we ever get from 2% of the BEVs on the road right now to 40%? Who currently subsidizes the construction of power plants and grid updates?
Really now, lets look at the cost of the product at the pump or charger... and I can bet you, a BEV world of 300 million vehicles will be much more costly to the USA consumer by getting rid of oil.
By the way, the USA is one of the top 3 exporters of oil in the world. Helping to cut our insane trade imbalance.
