> Adoption was happening at a fairly rapid pace while we were still oil independent. If by that you mean "net oil exporter", then that's not the full story. US oil refining infrastructure is geared towards decontaminating cheap, sulfur-rich (sour) crude and refining that. Meanwhile domestic resources are low in sulfur (sweet) and are exported at much higher prices than imports. Overall the US is not oil-independent despite being a net exporter because the current situation guarantees high margins and low domestic fuel prices.
