[] ** Where Does the Author work, what else has s/he written about, an what are his/her credentials? **  This is a report put out by the National Renewable Energy Laboratory. This is a government organization that does research on different renewable energy projects. ** What is the main topic of the text? **  The report is documenting a study on the effects of the introduction of corn ethanol into the U.S. gasoline supply and the change in price. They are looking to see how the price of gasoline has changed with the addition of ethanol. This change is quite small when compared to the money that has been invested and will need to be invested in the future to continue this growth. This report is also looking at the price of fuel before 2008, when it was much cheaper ($2.77 per gallon). ** Describe at least three ways that the main topic is fleshed out. **  The report shows that there is a reduction in the price of gasoline with the introduction of 10% ethanol. That price reduction around 17 cents per gallon, in 2008. However this is not consistent across the country, many regions do not blend at this same level. There are also negative effects of ethanol. It contains less energy per volume. Other problems include the need for updated infrastructure to support ethanol production and distribution. Also an entire new fleet of cars and trucks will need to be produced before an ethanol economy will be viable. ** What three quotes capture the critical importance of the text? **  “pure ethanol has and energy content roughly two thirds of that of fossil fuel” “significant changes to the fuel transportation infrastructure, gas stations and vehicle fleet may be required to increase the national ethanol concentration in gasoline.” “…cost associated with building-out of infrastructure needed for the higher ethanol blending concentration.” ** Explain how the argument and evidence in the text support you research focus. **  Ethanol can be used to offset curde imports in this country. This will alter the price of gasoline, however this changed comes at some cost that is not always considered. There is signifigant infrastructure costs associated with higher ethanol concentrations. A updated pipeline and tank system will be needed, also a new fleet of cars with be needed.
