What is a major drawback to the use of ethanol-based energy?

Burning ethanol releases greenhouse gases.


How does methanol impact the environment?

Did you mean Ethanol? IF so... Ethanol doesn't help the environment, just limits the use of fossil fuels. This Ethanol is a energy source similar to gasoline but is made from the Surplus Supplies from farms in the great plains. So in other words, it is just n alternative resource.


What are the pluses and minuses of using ethanol as energy?

pluses: ethanol is an altenitive energy. this means that if we use ethanol we become less dependant on petrolum. minuses: if more and more people become dependant on ethanol we, the US, will have to grow more corn to satisfy that demand.


What is a major drawback to the use of ethanol based energy?

Burning ethanol releases greenhouse gases. CO2 and water vapour


Is consequence and impact same?

When you say consequences they are all positive. When you say impact, they may be positive or negative, such as positive impact or negative impact. But we don't use phrases like positive consequence or negative consequence. But there are surely positive and negative impacts! What do you say?

Could you use ethanol to get to the moon?

Theoretically yes because ethanol can be used as a fuel but practically maybe difficult because you will need a lot of it to get enough energy.

Can ethanol save you fuel?

No, your car will actually use more fuel when run on ethanol or with ethanol added into the gasoline, as ethanol has less energy than gasoline. The reason ethanol is sometimes used is that it causes less pollution as it burns cleaner than gasoline and also can assist gasoline to burn cleaner when used as an additive.

Can nuclear energy use negatively impact water quality?

no


How can you overcome the use of energy in our environment?

That sounds as if you want to stop using energy. That's not possible - we need energy to survive. We (humans) can reduce our use of energy, and we can try to reduce the environmental impact of the energy we do use.


Why is ethanol not use as an electrolyte?

What is a use of ethanol produced by reacting ethene with steam?

the main use of ethanol is that some industries use it as a solvent.


Which is the best alcohol at producing energy and why?

Ethanol, due to it's inherent properties as a fuel. Brazil produces alot of Ethanol and is about to become energy independent because of it. But check this out: Crops such as corn, Sugar cane, beets, etc.. are converted to alcohol. In the case of corn to ethanol, it is energy negative. It takes 71% more energy to produce ethanol than is obtained from the ethanol. Also, using grain such as corn for fuel precludes it from being used as food for humans or livestock. It is also hard on the land. In United States corn production, soil erodes some 20-times faster than soil is formed. Ethanol has less energy per volume than does gasoline, so more gasoline has to be purchased to make up the difference. Also, ethanol is not environmentally friendly, as advocates would like to believe. Pimentel (1998) states: "Ethanol produces less carbon monoxide than gasoline, but it produces just as much nitrous oxides as gasoline. In addition, ethanol adds aldehydes and alcohol to the atmosphere, all of which are carcinogenic. When all air pollutants associated with the entire ethanol system are measured, ethanol production is found to contribute to major air pollution problems." With a lower energy density than gasoline, and adding the petroleum energy used to plow, plant, cultivate, and transport the corn for ethanol production, ethanol does not save gasoline nor does it's use reduce atmospheric pollution. A comprehensive study of converting biomass to liquid fuels by Giampietro and others (1997) concludes: "Large-scale biofuel production is not an alternative to the current use of oil, and is not even an advisable option to cover a significant fraction of it." Solar Energy is the only way to fly ;-)


What is ethanol use in everyday life?

ethanol is used in everyday life as eating sugar which contains ethanol.


What are the concerns of using ethanol as a fuel?

Ethanol has many considerations as far as its use as an automotive fuel.\: # On the plus side it is a liquid and easily handled in the present transportation and delivery systems. # On the negative side: * Ethanol from food crops removes food from the system * It requires more energy to produce ethanol than the automobile gets out of the ethanol (Crops require fertilization and fertilizers are made using hydrocarbons, ethanol is made by fermaentation, the fermentation products require distillation, the ethanol is a less efficient fuel than gasoline) * Ethanol combustion creates tail pipe emissions of aldehydes and ketones at levels not present in hydrocarbon fuelled autos * There is not enough land to produce enough ethanol fuel while maintaining food production * Ethanol from waste cellulose is not being pursued asa production route
