Answer 1

I will answer the 4 questions

Q.7) As the crude oil prices are increasing, ethanol drive was conducted in USA

Q.8) Net energy Return is of foremost important as this gives us an idea where to invest and what returns we can expect and hence according to requirements we can establish a plant.

Q.9) True. producing ethanol from corn (which is the method used in the US) is approximately 5 to 6 times less efficient than producing it from sugarcane.

Q.10) India has the best conditions for production of Bio-fuel.
