1. What is a renewable resource? Why is ethanol described as a renewable resource? * A renewable resource is a natural resource with the ability to reproduce through biological or natural processes and replenished with the passage of time. Renewable resources are part of our natural environment and form our eco-system.
* Ethanol fuel is ethanol (ethyl alcohol), the same type of alcohol found in alcoholic beverages. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline.
What potential is there to use ethanol as an alternative car fuel? *
Ethanol can be used in internal combustion engines if it can be economically produced from renewable resources or subsidized as a fuel to reduce air pollution.
The advantages of using ethanol include its complete combustion with minimal pollution. It can also be made in a number of ways. See the diagram below.
What are three advantages and there disadvantages of using ethanol as an alternative fuel?
Due to use a plant to produce ethanol, since it can photosynthesize if there are water and the sun, in the theory top, the worries about drain are considered to be quite low as compared with fossil system fuel, such as oil.
CO2 discharge zero
Carbon dioxide (CO2) emission can be considered to be zero from a carbon-neutral theory. Moreover, not only carbon dioxide but discharge of SOx (SOx) can be suppressed to zero, and carbon monoxide, hydrocarbon, etc. can be pressed down in a small quantity.
Ethanol is far more clean burning and requires less oxygen to undergo complete combustion due to the oxygen atom present in each molecule hence it is far cleaner burner which doesn't produce harmful chemicals like carbon monoxide as in petrol based cars.
At present, as compared with gasoline, cost becomes comparatively high-priced even on...
