Spational modeling of a sustainable gas supply chain by matching supply and demand Biogas production from co-digestion of cattle manure and biomass can have a significant contribution to a sustainable gas supply when this gas is upgraded to specifications prescribed for injection into the national gas …

There is no clear overview of the current dietary practices and problems with regard to elephants within Dutch and Belgian zoos, so to be able to assess whether zoos comply with current requirements. The goal of this study was to gain insight in the present feeding practices of the African (Loxodonta …

This dissertation explores the controversial concept of the green economy and the rapidly increasing environmental concerns associated to the heavy energy industry. The main objective of this paper is to investigate how China's 12th Five-Year Plan responds to the green economy paradigm. Hence, it examines …

In this paper the design and development of a new type of greenhouse with an integrated filter for reflecting near infrared radiation (NIR) and a solar energy delivery system is described. Especially the optical parts as the spectral selective film, the properties of the circular reflector and the efficiencies …

We present a novel method to achieve light trapping in thin film silicon solar cells. Unlike the commonly used surface textures, such as Asahi U-type TCO, that rely on light scattering phenomena, we employ embossed periodically arranged micro-pyramidal structures with feature sizes much larger than the …

Biogas can be seen as a flexible and storable energy carrier, capable of absorbing intermittent energy production and demand. However, the sustainability and efficiency of biogas production as a flexible energy provider is not fully understood. This research will focus on simulating biogas production …

Ymere and the city Almere will in the next ten years develop the residential area Almere Hout Noord. The ambitious targets of this area is a CO2 neutral and energy independent neighborhood with an EPC demand of 0,4. Because of the area's limitations an investigation into air source heat pumps was needed …

A new type of greenhouse with linear Fresnel lenses in the cover performing as a concentrated photovoltaic (CPV) system is presented. The CPV system retains all direct solar radiation, while diffuse solar radiation passes through and enters into the greenhouse cultivation system. The removal of all direct …

This research is done in order to create the best strategy for Philips Lighting in the changing markets of recently. The goal is to create opportunities while the European legislation concerning the incandescent light bulbs forces the company to gradually remove all its incandescent lamps. The legislation …

Energy efficiency has gained a lot of prominence in recent debates on urban sustainability and housing policy due to its potential consequences for climate change. At the local, national and also international level, there are numerous initiatives to promote energy savings and the use of renewable energy …
