On the Maximal Output Energy Density of Nanogenerators

ACS Nano, 2019
Nanogenerators have been demonstrated as a high-efficiency energy harvesting technology, while methods to evaluate merits of nanogenerators are being focused. Energy density, as a common way for evaluating energy devices, is believed to be strongly related to the output performance limit of nanogenerators.

Modelling the energy-output ratio

Energy Economics, 1984
Abstract The elasticity of energy use with respect to national output has been estimated by various methods with sometimes seemingly contradictory results. This study attempts to reconcile these various estimates by modelling the energy–output ratio and deriving the corresponding cross-section and time-series elasticities from this model.
