Question 14

Read the following scenario and answer the question below.
The United States consumes 25% of the worldʹs petroleum. Most is used for transportation, and most of it is imported. In 1992, after the first Gulf War, the federal government passed the Energy Policy Act, whose goal was to replace transportation-related petroleum with alternative fuels. Biodiesel made from vegetable oil or animal fat is an economical alternative to petroleum-based fuels. It is safe, biodegradable, nontoxic, and has the highest energy balance of any liquid fuel. Unlike unrefined oils that can be burned directly as fuels, biodiesel can be used in conventional diesel engines without engine modification. It reduces wear without compromising performance, due to its high lubricity. It is renewable and emits far less air pollution when combusted as compared to petrodiesel. The raw material used to produce biodiesel exists in billions of gallons of vegetable oil used by restaurants each year, as well as in crops. Processing biodiesel yields an added benefit-its by-product, glycerine, is used to make soap. Although biodiesel burns well in pure form (B100), commonly it is blended with petrodiesel in mixtures such as B20 and B5, which reduce toxic air pollution proportional to their biodiesel content. Biodiesel is currently available at almost 500 filling stations nationwide. Demand is increasing due to federal and state tax incentives as well as the increased price and decreased availability of petrodiesel. More than 600 domestic fleets use biodiesel, including the military, NASA, Yellowstone National Park, and local governments. Many school districts use biodiesel-powered school buses. Musicians Neil Young, Bonnie Raitt, and Willie Nelson fuel their tour buses with biodiesel. Nelson, a lifelong supporter of American farmers, who benefit when their crops are used for fuel, sells his own brand, BioWillie Biodiesel, at many truck stops. Because biodiesel can be manufactured locally, fuel transportation costs are low, and dependence on foreign petroleum and the need for domestic oil exploration and development of sensitive wildlife areas, such as the Arctic National Wildlife Refuge, can be reduced when biodiesel is used as an alternative fuel. There is concern, however, that biodiesel from crops may not be sustainable in the long term. Crops which are potentially food for humans, such as rape seed and soy, affect the price of foods and also require land, pesticides, fertilizers, and irrigation which may contribute to environmental degradation and stress on already limited resources.
-Compared to other uses of bioenergy, biodiesel from restaurant waste represents one of the best environmental alternatives to fossil fuels because they ____________.

Accepted Answer

A)  are the only form of bioenergy that reduces fossil fuel use 
B)  are the only form of bioenergy that is renewable 
C)  are the most available 
D)  require less processing than other forms of bioenergy 
E)  can be manufactured without the development of additional cropland agriculture
