• Trends in biotechnological production of fuel ethanol from different feedstocks. (2008, background): “The employ of starchy crops, specifically corn, for bioethanol production has provoked a hot debate on the suitability of these raw materials considering the energy input required for their production (Patzek et al., 2005; Pimentel, 2003; Shapouri et al., 2003; Wang et al., 1999a).”
• World crop residues production and implications of its use as a biofuel. (2005, background): “Pimentel (2003) argued that about 29% more energy is used to produce a gallon of ethanol than the energy in the gallon of ethanol.”
• ENERGETIC AND ECONOMIC FEASIBILITY ASSOCIATED WITH THE PRODUCTION, PROCESSING, AND CONVERSION OF BEEF TALLOW TO A SUBSTITUTE DIESEL FUEL (2006, background): “For example, Pimentel [13] considers energy embodied in farm machinery in his analysis of corn-based ethanol while Shapouri et al [15] do not.”
• Bioenergy from “surplus” land: environmental and socio-economic implications (2012, background): “Primary energy consumption of 1.6 GJ per oven-dried tonne for pelleting is equivalent to 9% of biomass energy content (Smeets et al. 2009) – this is efficient compared with production of liquid biofuels that may use more energy than they produce (Pimentel 2003; The Royal Society 2008).”
• Interactions between water, energy, food and environment: evolving perspectives and policy issues. (2008, background): “According to Pimentel (2003) poor consumers will loose out against rich car owners.”
• Food Versus Biofuels: Environmental and Economic Costs (2009, methodology): “…significantly more grinding, cell exploding with steam, and hot sulfuric acid are used a Data from Table 4 b Calculated for 144 km roundtrip c Pimentel (2003) d 15 l of water mixed with each kilogram of biomass e Pimentel et al. (2004) f Pimentel (2003) g Newton (2001) h Calculated based on…”
• Tillage and rotation effect on corn–soybean energy balances in eastern Nebraska (2007, background): “Reported energy input values vary from 19 GJ ha� 1 (Wang et al., 1997 )t o 33 GJ ha � 1 ( Pimentel, 2003 ) and 36 GJ ha� 1 (Ceccon et al., 2002) for corn production and from less than 10 GJ ha� 1 to almost 17 GJ ha� 1 for”
• Biofuel Impacts on World Food Supply: Use of Fossil Fuel, Land and Water Resources (2008, background): “…was divided by the industry-reported bushels of corn inputs to ethanol plants [86]. b) Data from table 4. c) Calculated for 144 km roundtrip. d) Pimentel, 2003 [87]. e) 15 liters of water mixed with each kg of grain. f) Pimentel et al., 2004 [31]. g) Pimentel et al., 2004 [31]. h) 4 kWh of…”
• Two sides of the same coin: consequential life cycle assessment based on the attributional framework (2016, background): “Notably, research by Pimentel and colleagues was all-negative for corn ethanol (Pimentel, 2003; Pimentel and Patzek, 2005).”
