Ethanol is expensive to make. The fuel efficiency for E85 based vehicles are less compared to the ones running on gas. Besides this ethanol has to be carried in trucks or trains (as there are no pipelines) which requires more fuel to be spent.

I dont think so, as ethanol has a good octane number(about 110-130, much much higher than premium petrols available today), it can be run in much higher compression ratios. The problem is when you try to run a conventional petrol engine using ethanol. The engine design need to be changed when the fuel u use is different.

And the expense in transporatation, even in case of Petroleum fuels u need to tarnsport, esp in places like India or Kerala where petroleum is nt in abundance. Where as if ethanol where made locally in India (the feasibility rate too, is high), there will be a drastic reduction in transportation costs.

Lemme also add that, ethanol (or any bio fuel) prodution should not be dependent on any particular fuel. Ethanol could also be prepared from cashew fruit, tapioca, hence the feasibility in Kerala is very high.

What happened to Bio-diesel? Is it now considered financially less feasible than ethanol?

“In Kerala where we stay, throwing garbage over the wall to the road is considered good civic sense”

LOL

Sadly this is the case with whole India,
I will say South is much better than North (with the exception of Chennai)
