I think it is worth to make it only if the feed for bioethanol is based on waste materials.

regards

Ruben Borrajo

Bio-ethanol was an important part of the fuel consumption for transportation in Brazil for several years. Mixed with gasoline is used for reduce the knocking properties of gasoline. I think that electrical vehicles is a goo option but probably there isn't enough lithium at the world for substitution of all fleet of vehicles in the world. Then bio-ethanol could be another option. There are researchers working in ethanol producing from ligno-celluloses materials.

Henrik Romar

Can ethanol produced from ligno-cellulose compete with ethanol from sugar cane or starch? Ligno-cellulose contains only 30% of cellulose, a substance hard to extract making the whole process expensive.

Rachan Karmakar

Use of any fuel not only depends on its usefulness only. So, if you ask this question, I must say it may happen. Due to several scientific and sociopolitical reason, the price of biofuels is still high and price is the primary factor behind the use of any fuel. eg. we know the use of coal is not eco-friendly. But it is still being used evidently. So, if electric cars get available in lesser price, it will take the market.

Now, if the question is asked about the usefulness of the fuel, bioethanol, which can be produced from bio-wastes, is my favorite. Because

1. It can be used in existing system of engines (may be with little modification)

2. It is a renewable fuel

3. It is an eco-friendly fuel

On the other hand, the resources of electric fuels' energy is not renewable.

If the electricity, of these vehicles, gets produced from renewable resorces, it can be accepted from the ethical point of view.

I work in the field of biofuel. Please got through my paper to have the importance of my view.

Article Production of biodiesel from unused algal biomass in Punjab, India

Dr. Rachan Karmakar

Rachan Karmakar I fully agree with the criteria You mentioned. But You can add one more point: It is produced from non-food resources.

Henrik Romar Definitely. I did not mention it as usage of it should be banned.
