Biomass production and energy balance of Miscanthus over a period of 11 years: A case study in a large‐scale farm in Poland

open access: yesGCB Bioenergy, 2019
Giant miscanthus (Miscanthus × giganteus Greef and Deuter) and Amur silver grass (Miscanthus sacchariflorus Maxim./Hack) are rhizomatous grasses with a C4 photosynthetic pathway that are widely cultivated as energy crops.

Comparison of PV Simulation Tools with Real-World Data: Residential Rooftop Systems in Surabaya, Indonesia [PDF]

open access: yesJournal of Renewable Energy and Environment
Accurate prediction of photovoltaic (PV) energy output is essential for system design, performance assessment, and investment decisions. However, the accuracy of widely used PV simulation tools in tropical residential settings remains insufficiently ...

Surfing the High Energy Output Branch of Nonlinear Energy Harvesters

open access: yesPhysical Review Letters, 2016
Hysteresis and multistability are fundamental phenomena of driven nonlinear oscillators, which, however, restrict many applications such as mechanical energy harvesting. We introduce an electrical control mechanism to switch from the low to the high energy output branch of a nonlinear energy harvester by exploiting the strong interplay between its ...

Coupled piezoelectric-circuit FEA to study influence of a resistive load on power output of piezoelectric energy devices [PDF]

open access: yes, 2009
This paper presents, for the first time, a coupled piezoelectric-circuit finite element model (CPC-FEM) to analyze the power output of vibration-based piezoelectric energy harvesting devices (EHDs) when connected to a resistive load.

Green urbanization.

open access: yesPLoS ONE, 2021
Large cities are more productive and generate more output per person. Using data from the UK on energy demand and waste generation, we show that they are also more energy-efficient. Large cities are therefore greener than small towns.

The energy output of the universe

open access: yesAIP Conference Proceedings, 2001
The total energy emitted by the growth of massive black holes is large and can be 10-50 per cent of that emitted by stars in the universe. I show how the X-ray Background provides a good measure of this energy and also why most accretion power is absorbed and re-emitted in the far infrared band. A model for the obscured growth of massive black holes is

Using net energy output as the base to develop renewable energy

open access: yes, 2011
In order to increase energy security, production of renewable energies has been highly promoted by governments around the world in recent years. The typical base of various policy instruments used for this purpose is gross energy output of renewable ...

Energy Accounting of Irrigated Wheat Production to Post Production (Baking Bread) in Doroodzan Fars Province, Iran

open access: yesAnnals of Tropical Research, 2011
The total energy input (TEI) of irrigated wheat in Fars province, Iran, was estimated at 901 liter diesel oil equivalent per hectare (LDOE ha-1) (423 LDOE or 4819 Mcal, (47%) and 478.14 LDOE or 5454 Mcal, (53%) for wheat production and post production ...
