Oil will still be critical. Aviation fuels... ALL plastics... The parts for so much of the machinery around us... It will be important...critical in fact... But alt energy is cheaper now...for vehicles, heating and power generation... Oils day as KING is done ... It won't recover to the reliance we had ...ever again...I believe... Some of the oil barons and guru's have already admitted after the last oil crash....that oil was done...it is just the ugly ...unprepared transition time we must deal with... Oil may be ugly in how we have abused it...But say for example... farm and textile and factory machinery, earth moving machinery ,... and with all that massive labour and time saving machinery ..powered by oil....we have insanely...at mad speed built our buildings, hydro electric dams, whole sewer systems, cities, fiber optics, hell the smartphone everyone holds...made with oil based plastics...AND the process of the making of the devices ..oil based plastics.. Most of the clothes people wear! if not oil based plastics then process derived ... and the shipping of everything we buy! it didn't come by foot! . turn of the century... 1 barrel of oil powered a machine to do the labour of 10 men in an hour that took them a day....that was the brute advantage that oil gave us to create the world we live in...and elevate everyone's standard of living to...to be able to produce the tech we have now to finally ween ourselves off oil.... I think those who despise oil or say it is an evil...Better take a good hard look at the EPIC hypocrisy of such a statement. Our civilization made it this far this fast ..Now we must ween ourselves from it quickly to conserve this limited finite resource ....or what's left of it...rather... Blunt of it is...we need to conserve what oil the planet has for critical needs of the future. Stop the waste of the finite resource...because we will need it badly in the years to come...
