Around the world, green certificate systems are widely employed as support mechanisms for the promotion of renewable energy production. Due to large initial capital costs for renewable energy projects, investment cost reduction policies are often employed by policy makers as complementary...

International Rivers strongly supports policy measures that can promote a rapid expansion of renewable energy sources. But these measures need to be based on a holistic understanding of sustainability. Large hydropower projects are not a renewable source of energy, can produce significant...

An excel-based model was developed to evaluate economic and environmental benefits of the solar-powered compaction garbage bins in public areas in Australia. Input data were collected from Brisbane and Wollongong City councils, and Sydney Olympic Park. The results demonstrate that solar-powered...

An integrated evaluation of embodied energy, greenhouse gas (GHG) emission, and economic performance of a wind power generation system in China was conducted, using a range of indicators. Energy and GHG emission costs per unit profit are proposed as goal functions for potential low-carbon,...

Nitrous oxide (N2O) emissions from agricultural land use account for 56% of German agricultural green house gas (GHG) emissions. It is assumed that this share will increase up to 60% by 2020. The realistic estimation of N2O emissions for GHG inventory and policy scenarios requires a model...

Biomass is expected to become an important energy source in U.S. electricity generation under state-lead renewable portfolio standards. This paper investigated the greenhouse gas (GHG) emissions for energy generated from forest resources through pyrolysis-based processing. The GHG emissions of...

This manuscript reviews and compares the results of recent greenhouse gas (GHG) emission life-cycle analyses. Specific attention is paid to fossil energy technologies, nuclear and renewable energy technologies (RETs), as well as carbon capture and storage (CCS) and energy storage systems....

The way in which GHG (greenhouse gas) emissions associated with grid electricity consumption is handled in different LCA (life cycle assessment) studies, varies significantly. Apart from differences in actual research questions, methodological choices and data set selection have a significant...

The environmental performance of production and distribution of densified form of lignocellulosic biomass (i.e., agri-residue based pellets) in Western Canada in terms of energy and greenhouse gas (GHG) emission was assessed. The results show that energy usage and resulted emissions are highest...
