Based on visual interpretation of high-resolution (30 m) satellite images, a new study in the journal Global Change Biology: Bioenergy determined that industrial plantations covered over 3.1 Slightly more than half of the GHG emissions for these biofuels in the EPA’s analysis came from land use change. Earlier post.). —Dr.
New research by the IHS Markit Canadian OilSands Dialogue shows that the combined greenhouse gas (GHG) intensity of Canadian oilsands projects has declined 20% from 2009 levels. The latest data show that the greenhouse gas intensity of Canadian oilsands going down further, continuing a decade-long trend.
Growth of production of Canadian oilsands. The Canadian oilsands are now poised to become the number one source of US crude oil imports in 2010, according to new research from the IHS CERA Canadian OilSands Dialogue. The Role of Canadian OilSands in US Oil Supply”.
A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oilsands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.
The US State Department today said that, “ particularly given the concentration of concerns regarding the environmental sensitivities of the current proposed route through the Sand Hills area of Nebraska ”, it needs to undertake an in-depth assessment of potential alternative routes in Nebraska.
The five different fuel groups were those derived: from conventional petroleum; from unconventional petroleum; synthetically from natural gas, coal, or combinations of coal and biomass via the FT process; renewable oils; and alcohols. million bpd. Reduced GHG impact. Certain HRJ and FT fuels are able to reduce the GHG emissions from aviation.
A team from Stanford University and the California Air Resources Board (ARB) has developed a new open-source lifecycle analysis (LCA) tool for modeling the greenhouse gas emissions of oil and gas production using characteristics of specific fields and associated production pathways. —El-Houjeiri et al.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.

In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).
Gasoline section shows results for fuel derived from both conventional oil and oilsands. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty whether shale gas emissions are actually lower than those of conventional natural gas.

Processes such as oil extraction from sources such as tar sands and deep-water offshore oil wells, as well as the expansion of first-generation biofuels such as corn-based ethanol are setting the stage for a “ water/energy collision ” of resource management policies. Climatechange. Metals and Mining.
World oil prices have fallen sharply from their July 2008 high mark. As the world’s economies recover, higher world oil prices are assumed to return and to persist through 2030. In the IEO2009 reference case, world oil prices rise to $110 per barrel in 2015 (in real 2007 dollars) and $130 per barrel in 2030.
While natural gas is often cheaper than oil and gives off fewer emissions, developing the resource comes with risks, especially for smaller nations. MIT and CyI researchers have been working together on initiatives of importance to the Mediterranean island nation and the region with the focus on water, energy, and climatechange.
Compared to a traditional flow battery of comparable size, it can store 15 to 25 as much energy, allowing for a battery system small enough for use in an electric vehicle and energy-dense enough to provide the range and the speedy refill of a gasoline-powered vehicle. The battery possessed a wide operational range of between -40 °C and 80 °C.
The US Department of State (DOS) has released its Draft Supplemental Environmental Impact Statement (SEIS) in response to TransCanada’s May 2012 application for the Keystone XL pipeline that would run from Canada’s oilssands in Alberta to Nebraska. The pipeline would primarily transport crude oil from the WCSB and Bakken regions.
Folks who quote the math of the old system like a well memorized mantra are limited by the notion that no other system will ever exist, while in fact, super capacitive storage systems currently use higher voltages, in the 3000 volt range and rising, to attain larger power transfers, faster, and on lighter wiring!
Incremental well-to-wheels GHG emissions from WCSB OilSands Crudes Compared to Well-to-Wheels GHG Emissions from Displacing Reference Crudes Click to enlarge. Domestic production of crude oil has increased significantly, from approximately 5.5 That portion of the pipeline has already been built. million bpd in 2010 to 6.5
The determination by the State Department brings to an end the much delayed, deferred and debated permit process that would have allowed TransCanada to built the fourth phase of its Keystone pipeline system to bring more oilsands crude from Canada to refineries in the US.

In a pre-response to that speech, having successfully advocated for plug-in hybrids like the forthcoming Chevy Volt, we propose that the President follow that speech up with a “realistic and conservative” roadmap to halve our oil use in 10 years. Oil is holding us all hostage, economically and physically. Finally, it’s time to begin.
In the 15 months that have passed since I wrote the following, ALL the climatechange news has gone from bad, to worse, to much worse than that. For the past three months I’ve been working night and day as the Chairman of the South Bay Los Angeles 350 Climate Action Group.
Otherwise it will become impractical to constrain atmospheric carbon dioxide, the greenhouse gas produced in burning fossil fuels, to a level that prevents the climate system from passing tipping points that lead to disastrous climatechanges that spiral dynamically out of humanity’s contro l.”.
Standardized values (Z scores) of (A) visible reflectance spectroscopy (VRS) chlorophyll a inferences from the five lakes proximate to major oilsands operations as indicators of lake primary production; (B) total PAH concentrations and (C) total DBT concentrations from all six study sites.

The four-door sedan will deliver 40 miles on a charge; a small gasoline engine will recharge the battery as it approaches depletion, extending its range by as much as 200 miles. GM killed that car because of back room deals with oil companies, and now they expect us to believe that they are just so cutting edge now?
