Not really. ER/EI of 2 means you would have to waste half your production of fuel to make the next crop of fuel. It's calculated that society will not run on energy ER/EI of less than 7. Way too expensive. Which will eventually even call into question some of the remaining oil reserves in tar sands, marginal shale plays, ect.
