Life Cycle Assessment (LCA) of Electricity Generation Technologies: Overview, Comparability and Limitations
Anthropogenic emissions of methane in the United States
Successful regulation of greenhouse gas emissions requires knowledge of current methane emission sources. Existing state regulations in California and Massachusetts require ∼15% greenhouse gas emissions reductions from current levels by 2020. However, government estimates for total US methane emissions may be biased by 50%, and estimates of individual source sectors are even more uncertain. This study uses atmospheric methane observations to reduce this level of uncertainty. We find greenhouse gas emissions from agriculture and fossil fuel extraction and processing (i.e., oil and/or natural gas) are likely a factor of two or greater than cited in existing studies. Effective national and state greenhouse gas reduction strategies may be difficult to develop without appropriate estimates of methane emissions from these source sectors.
Time Series EROI for Canadian Oil and Gas
Study presents a calculation of the energy return on investment (EROI) of Canadian unconventional and conventional oil and gas and find a 63% increase in energy investment in the O&G sector overall over the last two decades. This increase in energy invested has increased energy production just 18%. EROI for the sector and for tar sands alone are estimated at 11.1 and 4.1 respectively.
