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. The novel system shows potential for tackling global problems in a patient, thoughtful, and human-scaled way.

Univ. of Alberta and Helmholtz Association Partner to Develop Oil Sands Technologies to Address Environmental Issues

Green Car Congress

The goal of the initiative is to transform oil sands production processes by developing technologies that address sustainability challenges. The University of Alberta, recognized as a global leader in oil sands research, will work with the Helmholtz Association, a collection of 16 science and technology centers across Germany.

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. Keystone XL would add to global greenhouse gas emissions.

and are destined to rise significantly with the use of heavy oils, tar sands, and bitumen as combustion sources. Vanadium is a trace metal found in many earth materials, including petroleum and coal. Human emissions of vanadium to atmosphere now exceed natural sources by a factor of 1.7 —lead author William H.
