The National Renewable Energy Laboratory (NREL) has been collaborating with utilities and startups at the frontlines of high-renewable systems to make the technical and economic case for renewable fuels as we transition to a clean energy economy. With continued cost reductions for renewably generated electricity from sources like wind and solar systems, NREL is validating utility-scale hydrogen-production processes that could provide tomorrow’s clean fuels and chemical feedstocks to produce low-carbon, high-value products.

The melting of polar ice is not only shifting the levels of our oceans, it is changing the planet Earth itself. Newly minted Ph.D. Sophie Coulson and her colleagues explained in a recent paper in Geophysical Research Letters that, as glacial ice from Greenland, Antarctica, and the Arctic Islands melts, Earth's crust beneath these land masses warps, an impact that can be measured hundreds and perhaps thousands of miles away.

Society has just begun to tap new renewable sources of energy from agriculture and forestlands on a commercial scale that impacts energy markets. Among these sources are biofuels, a small but important component of current fuel consumption in the U.S. transport sector. In 2012, biofuels accounted for roughly 7.1 percent of total transport fuel consumption, or 13.8 billion gallons, unchanged from the previous year. Ethanol, made mostly from corn starch from kernels, is by far the most significant biofuel in the United States, accounting for 94 percent of all biofuel production in 2012. Most of the remainder is biodiesel, which is made from vegetable oils (chiefly soy oil) as well as animal fats, waste oils, and greases.

When the COVID-19 pandemic reached Georgia and healthcare facilities rapidly developed protocols and procedures for providing care in the new era of coronavirus, Emory’s medical students were pulled out of rotations in hospitals and clinics to shelter in place at home. Students were left pondering a world where global pandemics, social and environmental determinants of health, disaster preparedness, and the ability to mitigate risks to exposures are all connected to the health of patients, their families, and their communities. They also needed electives that could be implemented virtually, and soon.
