U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. Earlier post.). —Nduagu & Gates.

Researchers Suggest That Although CCS and Other Technologies Could Reduce Oil Sands GHG Emissions to Near Zero, That Strategy May Not Make Sense

Green Car Congress

Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., The source material is neither oil nor tar but bitumen, but is most generally described as an example of ultraheavy oil.”.

EIA projects world energy use to increase 53% by 2035; oil sands/bitumen and biofuels account for 70% of the increase in unconventional liquid fuels

Green Car Congress

World oil prices remain high in the IEO2011 Reference case, but oil consumption continues to grow; both conventional and unconventional liquid supplies are used to meet rising demand. In the IEO2011 Reference case the price of light sweet crude oil (in real 2009 dollars) remains high, reaching $125 per barrel in 2035.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. To meet this challenge, many governments and organizations are investing in new technology to help lessen the use of fossil fuels.
