Solution

The incorrect statement about bioethanol is:

d. increases the amount of greenhouse emissions.

Bioethanol is a form of renewable energy that can be produced from agricultural feedstocks. It can be used directly, or blended with gasoline to create a biofuel. Bioethanol has several advantages over traditional fuels. It is biodegradable and less toxic, helping to reduce pollution and improve air quality. It also increases the octane number, which can improve engine performance.

However, the statement that bioethanol increases the amount of greenhouse emissions is incorrect. In fact, bioethanol helps to reduce greenhouse gas emissions. When bioethanol is burned, it releases carbon dioxide. However, this is offset by the carbon dioxide absorbed by the plants that are used to produce bioethanol. Therefore, the net emissions of greenhouse gases from bioethanol can be lower than those from conventional fuels.

The statement that bioethanol reduces the fuel economy by 2-3 percent is also correct. Bioethanol contains less energy per gallon than gasoline, so vehicles may get fewer miles per gallon when using fuel blends with a high percentage of bioethanol. However, this can be offset by the other environmental and performance benefits of bioethanol.
