Less than 10% of Bakken oil is transported by pipeline. Around 2% of Canadian oil is transported to the US via train.
And as I understand it, Illinois and Iowa share an interconnected power grid, so while Illinois may be using more, the wind-powered kwh are shared by both states.
My first environmental job in 1971 was looking for water pollution problems and seeking abatement solutions. It was common for businesses to dispose used oil along fense lines as weed control. It was hard to convince them it was a problem. It killed the weeds and as the oil degraded new weeds came back so they thought there wasnât a problem. Back then there were even some engineering circles that sang âthe solution to pollution was dilution.â
My dad used to dump after oil changes, until the law changed. Surprisingly, he then followed and recycled it (or whatever they do with it to dispose of it).
