Satisfying global demand for energy, food, and goods without emitting CO2 to the atmosphere is a central challenge of the 21st century.  My research is aimed at understanding the scale of that challenge and finding ways to meet it.
Geophysical constraints on reliability of U.S. solar and wind power
Energy & Environmental Science | February 27, 2018

Analysis of hourly weather data shows that meeting >80% of U.S. electricity demand with only solar and wind would require days' or weeks' worth of energy storage--even assuming a continental-scale transmission grid. Today this would be very costly.

Eliminating natural gas at the UC
Nature Climate Change | February 27, 2018

The Paris Agreement highlights the need for local climate leadership. The University Of California’s approach to deep decarbonization offers lessons in efficiency, alternative fuels and electrification. Bending the emissions curve globally requires efforts that blend academic insights with practical solutions.

Targeted emission reductions from global super-polluting power plant units
Nature Sustainability | January 8, 2018

We assess fuel- and region-specific opportunities for reducing undesirable air pollutant emissions using a newly developed emission dataset at the level of individual generating units. Retiring or installing emission control technologies on units representing 0.8% of the global coal-fired power plant capacity could reduce levels of PM2.5 emissions by 8–14%.

Probabilistic estimates of drought impacts on agricultural production
GRL | August 5, 2017

Using a multivaritate probabilistic model, we quantify the average annual yields of major rainfed crops in Australia as a function of precipitation and soil moisture indices during the growing season. In the period 1980-2012, yields were 25–45% lower in dry seasons.
