Clean Energy for a Sustainable Future, Marina Mariano-Juste

YCEI’s 2015-2016 speaker series highlights the work of its postdoctoral fellows, beginning with Marina Mariano-Juste, a physicist who specializes in using light-trapping schemes to increase efficiency of photo-voltaic devices.  Marina’s Monday talk serves as an introduction to a more technical presentation by her principal advisor, Andre Taylor of the Yale School of Applied Science and Engineering which follows Tuesday at noon in Kroon Hall (lunch served).

Electricity Access for India's Poor is Minor Contributor to Emissions Growth

Rapid expansion of electrical service in developing countries is a common concern in the climate change community. The aspiration for universal access to electric power is understandable; electricity is crucial to alleviation of poverty, but the accompanying increased burning of fossil fuels to supply that energy potentially hinders efforts to mitigate climate change.

A recent study in Nature Climate Change uses two national datasets to quantify the…

Lifestyles of the High and Low GHG Emitters

Where should you live to most reduce your carbon footprint? It seems obvious that city life with smaller homes, mass transportation, and easy access to shops and restaurants is preferable to the suburbs with its cars and bigger homes. But how about the benefits of rural areas where people grow their food and live closer to the land? What about regional climate, income and energy price differences? A recent analysis by Jones and Kammen (2013)…

Intergenerational Differences in Carbon Emissions

Changing people’s carbon emission patterns requires first understanding the differences in behaviors and corresponding emissions levels between different groups of people. A recent paper by Chancel in the journal Ecological Economics investigated the differences in carbon emissions between different generations in the U.S. and France. The author examined carbon emissions by American and French

Light Management Key to Reaching Solar Cell Efficiency Limit

In 1961, the Nobel Prize-winning co-inventor of the transistor, William Shockley, and his colleague, Hans Quisser, identified the theoretical maximum conversion efficiency of a solar cell. They called this the “detailed balance limit,” because maximum efficiency would occur when photons absorbed from and emitted to the sun were in the proper balance. This theoretical limit has been beyond the…

Benefits Outweigh Costs of Massive Renewable Energy Deployment

The power grid is a massively complicated network of generators, power converters, and transmission lines controlled through the cooperation of numerous private corporations and local and international agencies. Grid operators rely on long and short-term “to-the-minute” weather predictions and other inputs to predict demand and prevent disruption. Government policies and economic constraints of the coming decades require the grid in the United States (and elsewhere) to become even more intelligent, interconnected, and efficient.
