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

Our tool provides a simple method to integrate disparate climate and population data sources and develop preliminary per capita water availability projections at a global scale. At that time, it was unusual to integrate population, climate and water data into one model. —Esther Parish, lead author. —Esther Parish.

Debunking the Lithium "Mining" FUD

Plug In India

For example - the process of obtaining lithium from brines can be more sustainable by condensing evaporated water so it can later be returned to the ground. A completely new method is to filter lithium directly out of the brine using membranes, thus avoiding water-intensive evaporation [8].

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil. The growth in hydrous ethanol, which uses a blend of 94-95% ethanol to 5-6% water, rapidly increased during the 1980s, with consumption peaking in 1989.
