Why America Can't USE The Oil it Produces

Why America Can't USE The Oil it Produces
After the 1973 OPEC oil crisis, recommendations were made to decrease the USA from foreign oil dependence, such as improving fuel economy in future vehicles (the CAFE standard), investing in renewable energy production (solar, hydro, geothermal, wind, etc.), converting municipal vehicles to natural gas & efficient electric hybrids, only import oil from Canada & Mexico, not to export US oil, and so on. But the US petroleum corporations killed those ideas by bribing Congress with campaign donations and other gifts.
It can still be done and with an investment to switch domestic refineries to handle shale oil, the US, Canada & Mexico can free themselves from OPEC, and perhaps the US can free herself from fighting oil wars in the future.
