Wasted Food, Wasted Energy: The Embedded Energy in Food Waste in the United States
This work estimates the energy embedded in wasted food annually in the United States. We calculated the energy intensity of food production from agriculture, transportation, processing, food sales, storage, and preparation for 2007 as 8080 +/- 760 trillion BTU. In 1995 approximately 27% of edible food was wasted. Synthesizing these food loss figures with our estimate of energy consumption for d...
متن کاملQuantifying Wasted Write Energy in the Memory Hierarchy
Wasted writes occur when modified cache lines are evicted and written back to main memory even though the data contained in those lines is no longer needed by the program or does not change the existing memory contents. Wasted writes include values in retreating stacks and values in heap objects that have been deallocated. They also occur as a result of unmodified data values being written back...
متن کاملToward a Test Protocol for Conducted Energy Weapons
Conducted Energy Weapons (CEWs), such as those manufactured by TASER International Inc., are seeing increased use by law enforcement agencies as a less lethal force option; but, at the same time, these weapons are also seeing an increased level of concern in terms of their safety of use. In order to enable consistent evaluation of CEW performance, a systematic protocol for testing the electrica...
متن کاملNuclear Weapons Proliferation Implications of Thermonuclear-Fusion Energy Systems
This paper contains two parts: (I) A list of “points” highlighting the strategic-political and militarytechnical reasons and implications of the very probable siting of ITER (the International Thermonuclear Experimental Reactor) in Japan, which should be confirmed sometimes in early 2004. (II) A technical analysis of the nuclear weapons proliferation implications of inertialand magnetic-confine...
متن کاملWasted Food, Wasted Nutrients: Nutrient Loss from Wasted Food in the United States and Comparison to Gaps in Dietary Intake.
BACKGROUND Previous research has estimated that wasted food in the United States contains between 1,249 and 1,400 kcal per capita per day, but little is known about amounts of other nutrients embedded in the 31% to 40% of food that is wasted. OBJECTIVE This research aimed to calculate the nutritional value of food wasted at the retail and consumer levels in the US food supply, and contextuali...
