An analysis of energy use, input costs and relation between energy inputs and yield of apple orchard [PDF]

open access: yesResearch in Agricultural Engineering, 2011
This study examines the energy balance between the input and the output per hectare for an apple orchard in the West Azarbaijan province in Iran (2008-2009). Data were collected by using random sampling method for 80 "face to face" questioners.

Energy Input Interaction in US Output

open access: yesReview of Economic Analysis, 2022
This paper estimates production functions for annual US output from 1949 to 2013 adding energy Btu input to fixed capital assets and the labor force.  Interactions between inputs are parsimoniously introduced in the error correction estimates.  Fixed capital assets successfully imbed technology.

Simulation of Energy Input to Solar Panels [PDF]

open access: yes2019 International Ural Conference on Electrical Power Engineering (UralCon), 2019
The article reviews the assessment methods of energy supplied to the surface of solar panels. The need of increase in accuracy of calculation of the solar energy entering on the panel is proved due to the accounting of additional influencing factors. A technique for estimating solar energy to the surface of panels is developed. The degree of cloudiness

Exploiting Input Variations for Energy Reduction [PDF]

open access: yes, 2007
The deep submicron semiconductor technologies will make the worst-case design impossible, since they can not provide design margins that it requires. Research directions should go to typical-case design methodologies, where designers are focusing on typical cases rather than worrying about very rare worst cases.
