Whether they generate it on-site or elsewhere, if you just stopped refining and distribution for ground transportation fuels, you would have more than enough electrical energy freed to power the ground transportation system (assuming you had the batteries/lines to do it). Back in 2006, I found a Caltech doctoral thesis where this was studied carefully, I'll try to find it. A quick google found this:JRP3 wrote:Somewhat true. Much refinery electricity is generated on site from petroleum and petroleum by products, a smaller percentage comes from the grid. From what I've researched by not refining oil we make up for some of the power drawn from the grid by an EV but not all. Also oil is refined into other products besides transportation fuels so not all refinery electricity goes into gasoline production. Because of that my statements remain accurate regarding grid tie solar.Ingineer wrote: Actually, if you AREN'T using gas in your car, the Electricity saved from just Petroleum Refining and Distribution operations will power your EV and then some. The Largest single consumer of electricity California are Petroleum operations. Assuming you replace a gas car with an EV, and charge off-peak, we end up with a more stable grid, and a little less electricity use.
Without a doubt, the largest single industrial user of Electricity and Natural Gas energy is the Petroleum industry. This is true for California, and the US as a whole. Most people don't know this, and it's a scary bit of information!
