Incorporating renewables in the power grid has challenges in terms of the stability, reliability,
and acceptable operation of the power system network. One possible solution is to integrate …

Under many scenarios, fossil fuels are projected to remain the dominant energy source until
at least 2050. However, harder-to-reach fossil fuels require more energy to extract and …

Numerous analyses of mono-and polysilicon Solar-Photovoltaic (PV) modules provide an
Energy Payback Time (EPT) or Net Energy Ratio (NER) value. Few are directly comparable …

Many people believe renewable energy sources to be capable of substituting fossil or
nuclear energy. However there exist very few scientifically sound studies, which apply due …

Most earlier civilizations, and many today, attributed their existence, well-being and rules for
proper behavior to a powerful God or gods. Our civilization, and indeed earlier ones, has a …

The net energy implications of the energy transition have so far been analysed at best at the
final energy stage. Here we argue that expanding the analysis to the useful stage is crucial …

The projects that combine solar photovoltaics (PV) and poverty alleviation (PA) are the
explorations of sustainable development (SD) from the Chinese government, aiming at both …

A recent paper by Ferroni and Hopkirk (2016) asserts that the ERoEI (also referred to as
EROI) of photovoltaic (PV) systems is so low that they actually act as net energy sinks, rather …

Energy inequity is an issue of increasing urgency. Few policy-relevant datasets evaluate the
energy burden of typical American households. Here, we develop a framework using Net …

High cost and technical immaturity of bulk (multi-hour) electricity storage (BES) systems are
often cited as major hurdles to increasing the penetration of intermittent renewables. We use …
