By Raindog on March 8, at 2: What do you think about the role that CNG vehicles might play in the next ten years? Can you compare the environmental footprint of a CNG vehicle that burns gas directly versus an electric vehicle that uses electricity produced from gas? Actually maybe an EV is more efficient.
But the advantage of the EV is that you can use electricity from any source, including renewable energy. The disadvantage is the range limitation and battery raw materials needed to build the EV. A few years ago, if you looked up the EROEI of oil sands, that is the number that you found but it was never referenced.
I was always a bit suspicious of it, because oil sands were being developed even when gas prices were higher, and I did not think a 3: I first calculated the 8: The purpose of the essay was merely to educate readers on the process, but actual industry gas usage numbers were presented.

I have seen estimates ranging from 3 to 8. Based on my data I think it is about 5: But we also have to factor in the additional energy besides just extracting the oil sand and upgrading it to SCO.
It also needs to be transported, then further refined into final products. Here are mine leading to about 5:Troop deployment creates tense atmosphere on US border Jesse Quist was one of two winners in the "Breaking Barriers" essay contest. A large storm system moving through the Gulf Coast.
