Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

In a paper published in the ACS journal Environmental Science & Technology , Stanford University assistant professor Adam Brandt reviews a number of recent life cycle assessment (LCA) studies calculating greenhouse gas (GHG) emissions from oil sands extraction, upgrading, and refining pathways—the results of which vary considerably.

ES&T editorial calls Keystone XL a “pipeline to nowhere”

Green Car Congress

Use of coal, oil, and natural gas has to stop (in that order). But “dirty” oil, emanating from oil sands (a.k.a., tar sands) with a significantly higher carbon footprint than conventional oil, deserves a place at the front of the line. but this dog will not hunt. It is a slippery (and oily) slope.

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. These initiatives have largely focused on renewable electric power generation, distribution, and storage. Eronen says, laughing.
