An imlementation of life-cycle analysis (LCA) for energy systems is presented and applied to two renewable energy systems (wind turbines and building-integrated photovoltaic modules) and compared with coal plants.

This paper presents a life-cycle analysis for a new concept in solar thermal power generation. BRRIMS denotes Brayton-cycle, re-heated, recuperated, integrated, modular and storage-equipped. This concept envisages collection temperatures of around 250 °C, thermal storage in pebble beds,...

A CO2 comprehensive balance within the life-cycle of a photovoltaic energy system requires careful examination of the CO2 sinks and sources at the locations and under the conditions of production of each component, during transport, installation and operation, as well as at the site of...

Life-cycle fossil primary energy consumption (FPEC) and greenhouse gas (GHG) emission intensity of nine types of dominant secondary energy (SE) pathways for China in 2010 are calculated with iterative methods, using the TLCAM (Tsinghua Life-cycle Analysis Model). Three major types of GHG (CO2,...

The role of forests in our environment is increasing in importance due to the multifunctional benefits forests provide to urban and rural communities in relation to climate change mitigation, water conservation and the provision of fibre for bioenergy. However, afforestation targets across...

This paper reports meta-regressions of substitution elasticities between greenhouse-gas (GHG) polluting and nonpolluting inputs in agricultural production. We treat energy, fertilizer, and manure collectively as the “polluting input” and labor, land, and capital as nonpolluting inputs. We...

We present results from an application of the Biofuel Breakeven program (BioBreak) to 14 US cellulosic ethanol markets that vary by feedstock and location.  BioBreak estimates the economic costs of cellulosic biofuel production for each market and identifies the necessary conditions to sustain...

A life-cycle analysis (LCA) of greenhouse gas (GHG) emissions and energy use was performed to study bio-jet fuel (BJF) production from micro-algae grown in open ponds under Chinese conditions using the Tsinghua University LCA Model (TLCAM). Attention was paid to energy recovery through biogas...

Many new-entrant carriers enjoyed fast growth and by the same token sudden failure, therefore raising interest in the characteristics of their life cycles. The article proposes a different approach to life-cycle analysis of airlines by integrating an ‘evolution path’ based on size...

Options for reducing greenhouse gas emissions (GHGE), measured as global warming potential, in twelve crop and seven livestock systems were explored using a systems model-based life-cycle analysis of environmental burdens and resource use. Differences between crops in GHGE per kg product...
