Future of manufacturing

I’d like to ask everyones help in imaging what US manufacturing will become. In my area (Houston) oil and gas manufacturing is huge. I think O&G employs almost 20% of the entire metro area! But it’s clear that the global desire for oil is on the decline which means there will be a vacuum within the manufacturing sector. In addition the sentiment of the country seems to be wanting to move away from plastics and other products with a negative environmental impact.

How do we shift US manufacturing moveing away from O&G and the numerous industries that surround it in a way that supports both business owners and working class employees?
