New ORNL tool to assess global freshwater stress suggests that population growth could be a bigger factor in water availability than increasing temperatures

Green Car Congress

While several recent studies have suggested that much of the world is likely to experience freshwater shortages as the population increases and temperatures rise, determining the relative impact of each has been difficult. At that time, it was unusual to integrate population, climate and water data into one model.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The results of the study were published in the Journal of the Association of Environmental and Resource Economists. The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions.

Study using extreme value theory finds lack of uniform trends but increasing spatial variability in rainfall extremes in India

Green Car Congress

A new study utilizing extreme value theory (EVT) reports no evidence for uniformly increasing trends in rainfall extremes averaged over the entire Indian region. These findings, published in Nature Climate Change , are contrary to results of some earlier work on this subject. —Ghosh et al.

US DOE awards ~$5M to expand research on methane hydrates

Green Car Congress

When methane hydrates are “melted,” or exposed to pressure and temperature conditions outside those where the formations are stable, the solid crystalline lattice turns to liquid water, and the enclosed methane molecules are released as gas. Earlier post.). DOE Investment: approximately $1.68 DOE Investment: approximately $650,000.

DOE to offer up to $4.5M for research on methane hydrates

Green Car Congress

Methane hydrate—molecules of natural gas trapped in an ice-like cage of water molecules—is a potentially vast methane resource for both the United States and the world. Studies that address the potential environmental implications of production activities at a variety of temporal/spatial scales would also be of interest.

Argonne study finds shale gas GHG lifecycle emissions 6% lower than natural gas, 23% lower than gasoline and 33% lower than coal; upstream methane leakage a key contributor

Green Car Congress

The base results from a study by a team at the Center for Transportation Research, Argonne National Laboratory indicate that shale gas life-cycle greenhouse gas (GHG) emissions are 6% lower than conventional natural gas, 23% lower than gasoline, and 33% lower than coal. Expansion bars show the components of fuel production. Click to enlarge.

Columbia University engineers make breakthrough in understanding electroreduction of CO2 for conversion to electrofuels

Green Car Congress

Our findings about CO 2 activation will open the door to an incredibly broad range of possibilities: if we can fully understand CO 2 electroreduction, we'll be able to reduce our dependence on fossil fuels, contributing to the mitigation of climate change.
