Non-Parametric Energy Use Efficiency, Energy Ratio and Specific Energy for Irrigated Wheat Crop Production
In this paper, non parametric Data Envelopment Analysis (DEA) was subjected to the energy data of wheat producers in Punjab state, India, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. The main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...
متن کاملModernizing biomass energy
Biomass accounts for an estimated one-third of all energy used in developing countries today. Most of this biomass is used inefficiently and with significant pollutant emissions by the more than 2 billion people who cook using direct combustion of biomass. Contrasting today’s use of biomass energy, several recent major assessments of future global energy supply show much larger roles for biomas...
