Why is ethanol not widely used?

Higher-ethanol blends still produce significant levels of air pollution, reduce fuel efficiency, jack up corn and other food prices, and have been treated with skepticism by some car manufacturers for the damage they do to engines. Growing corn to run our cars was a bad idea 10 years ago.

Is petrol better than ethanol?

Petrol contains more energy than ethanol. If you burn one litre of petrol you get 33.5 million joules. That means there’s about 30 per cent less energy in a tank full of ethanol, compared with the same volume of petrol. And that means there’s about three per cent less energy in E10 compared with regular petrol.

Why is ethanol a good choice as a replacement fuel for petroleum?

Ethanol fuel has been lauded as a viable alternative to petroleum-based fuels, offering not only less pollution to the environment, but also a sustainable source of energy. Most vehicles run on mixtures of gas and ethanol; this mixture is common at most gas stations across the country.

Are ethanol and petroleum the same?

Much of the ethanol produced in the world is actually a petroleum product. It is easily made by the hydrolysis of ethylene, a major petrochemical. Two million tons of petroleum-derived ethanol is produced annually.

What is the advantage of using ethanol as fuel?

The most common use of Ethanol fuel is by blending it with gasoline. Doing so creates a mix that releases fewer emissions into the environment and is considered cleaner in nature. It also keeps the car in better shape by increasing the octane rating of the fuel.

Why is ethanol a good fuel?

What are pros and cons of ethanol used as fuel?

Ethanol. Pros: Reduces demand for foreign oil, low emissions, high octane, and can potentially be produced from waste materials; existing cars can use 10-percent blends (called E10), and more than 8 million cars already on the road can use E85. Cons: Twenty-five percent lower fuel economy on E85 than gasoline.

Why is ethanol free gas better?

Pure gas gives drivers better mileage. This is because gas mixtures like E10 and E15 have less free energy due to the added ethanol. Compared to regular and premium gas mixtures, non-ethanol gas is better for your overall mileage.
