Did you know that, the United States has vast oil and gas resources onshore and offshore that are currently illegal to develop and therefore inaccessible. U.S. law prohibits the development of approximately 38 billion barrels of undeveloped oil resources (19 billion barrels onshore and 18.92 billion offshore).
U.S. law prohibits the development of approximately 180 trillion cubic feet of undeveloped natural gas resources (94.5 trillion cubic feet onshore and 85.7 trillion cubic feet offshore).
I don’t know but it seems to me that these resources would go along way to providing us with the time necessary to develop and stabilize commercially viable alternative energy sources. Whether that be hydrogen, tidal, geothermal, wind, nuclear, solar, or other.
BTW, even though I have done some work in the ethanol industry I think it is pretty clear that using food for fuel is not really a viable alternative.
