Castellanos, Sergio

Ser­gio Castel­lanos is a Berke­ley Energy & Cli­mate Insti­tute – Tec­nológico de Mon­ter­rey (BECI–ITESM) Energy Fel­low work­ing at the Renew­able and Appro­pri­ate Energy Lab with Prof. Dan Kam­men. His research focuses on expand­ing an opti­miza­tion model –SWITCH– to Mex­ico to deter­mine the opti­mal invest­ments in new gen­er­a­tion and trans­mis­sion assets. Through his research, he also ana­lyzes the man­u­fac­tur­ing capac­ity of pho­to­voltaic solar tech­nolo­gies in Mex­ico. Pre­vi­ously, in his Ph.D. stud­ies (Mechan­i­cal Engi­neer­ing ’15, MIT) he char­ac­ter­ized the elec­tri­cal impact of struc­tural defects in silicon-​​based solar cells. He enjoys read­ing, explor­ing new hob­bies, and learn­ing more about the inter­sec­tion of tech­nol­ogy, busi­ness, and pol­icy in renew­able energy.

Prior to Berke­ley, he was a research asso­ciate with Stan­ford University’s Pro­gram on Energy and Sus­tain­able Devel­op­ment from 2008 to 2010.

Tiny House in My Backyard

Tiny House Competition

This event is open to all col­leges and uni­ver­si­ties in Cal­i­for­nia. Par­tic­i­pa­tion pro­motes an inter­est in energy con­ser­va­tion, energy effi­ciency and green build­ing and solar tech­nolo­gies. The Energy & Tech­nol­ogy Cen­ter and Com­mu­nity Solar are proud to spon­sor this event.

The Tiny House Com­pe­ti­tion – Build Small and Win Big” is a new com­pe­ti­tion in the Sacra­mento region, chal­leng­ing col­le­giate teams to design and build net-​​zero, tiny solar houses. The event is antic­i­pated to be held in the fall of 2016 and is spear­headed by SMUD’s Energy & Tech­nol­ogy Cen­ter and Com­mu­nity Solar®program.

The Com­pe­ti­tion
This event is mod­eled after the U.S. Depart­ment of Energy’s Solar Decathlon. An edu­ca­tor or other school admin­is­tra­tor will men­tor each team. Dur­ing the two years lead­ing up to the event, stu­dents will design and build the energy-​​efficient houses. A stipend between $3,000 — $6,000 will be provided.

Dur­ing the week of com­pe­ti­tion, stu­dents will exhibit their houses to the pub­lic, judges and the media. The ten cat­e­gories of the decathlon include archi­tec­tural design, liv­abil­ity, com­mu­ni­ca­tion, afford­abil­ity, energy effi­ciency and bal­ance, appli­ance load, technology/​electrical and mechan­i­cal sys­tems, trans­porta­tion, sus­tain­abil­ity and doc­u­men­ta­tion. On the last day, teams will be awarded tro­phies and mon­e­tary prizes.

Dead­line to apply
The dead­line to apply for the 2015 com­pe­ti­tion has passed.

Work­shop date
A Tiny House Work­shop is sched­uled for Novem­ber 14 & 15, 2014

My research is dri­ven by an inter­est in the broad-​​based envi­ron­men­tal and social impacts of energy tech­nolo­gies and poli­cies. This work seeks to make explicit the trade-​​offs that are often present between energy secu­rity, cli­mate, and other impor­tant social and envi­ron­men­tal objec­tives. In par­tic­u­lar, I have worked on issues at the water/​energy nexus, eval­u­at­ing the “water foot­prints” of a range of energy tech­nolo­gies. Water and energy are inex­tri­ca­bly linked, with elec­tric­ity gen­er­a­tion sec­ond only to agri­cul­ture in total global water with­drawals. This con­nec­tion is par­tic­u­larly acute for bioen­ergy, as it is by far the most water-​​intensive of all energy types. My research has employed life cycle assess­ment (LCA), agro-​​climatic mod­el­ing, and GIS tools to show that bio­fu­els rou­tinely require sev­eral orders of mag­ni­tude more water than petro­leum fuels while often pro­vid­ing only mod­est cli­mate benefit.

I approach my research with an eye toward imple­men­ta­tion. This has led me to work with Cal­i­for­nia reg­u­la­tory agen­cies on fuel pol­icy for­mu­la­tion and to serve as vice-​​chair of the Geneva-​​based Round­table on Sus­tain­able Bio­fu­els. Prior to com­ing to HSU, I worked in Rome for the United Nations Food and Agri­cul­ture Orga­ni­za­tion. While there, I pro­vided sup­port to the gov­ern­ments of Indone­sia and Colom­bia in eval­u­at­ing the envi­ron­men­tal and social impacts of their bio­fuel indus­tries, and in for­mu­lat­ing poli­cies to address those impacts.

Sustainable Energy for Kosovo and Southeast Europe


Energy effi­ciency, renew­able energy, and smart sys­tems inte­gra­tion pro­vides a rapid path away from local and glob­ally pol­lut­ing energy sys­tems.  This gen­eral assess­ment is par­tic­u­larly true for impov­er­ished areas or those impacted by con­flict.  This is the case because the mix­ture of energy effi­ciency and renew­able energy can gen­er­ally be deployed far more rapidly and in more dis­trib­uted a fash­ion than tra­di­tional, cen­tral­ized, energy systems.

Kosovo is par­tic­u­larly in need, and par­tic­u­larly amenable to this sort of “rapid and green” devel­op­ment plan.  This project, started to iden­tify and quan­tify oppor­tu­ni­ties to choose a clean path instead of an ongo­ing fix­a­tion on coal, has now spread to exam­ine both national and regional oppor­tu­ni­ties in South­east Europe.

My work exam­ines processes where human and nat­ural sys­tems inter­act and those that elu­ci­date the func­tion­ing of the Earth sys­tem. Answer­ing pure eco­log­i­cal research ques­tions and solv­ing crit­i­cal envi­ron­men­tal prob­lems through applied work are impor­tant to me. My research pro­gram to date is com­prised of three inter­con­nected themes:

1 | Energy Geog­ra­phy and Devel­op­ment  –  My energy research is moti­vated by the belief that every human should have access to energy in a man­ner that is sus­tain­able with the Earth sys­tem. I study the inter­sec­tion between energy devel­op­ment and the envi­ron­ment, and par­tic­u­larly how solar energy can be deployed to reduce green­house gas emis­sions, water deficits, and land-​​cover change. I am inter­ested in elu­ci­dat­ing how renew­able energy devel­op­ment can be real­ized at policy-​​relevant timescales to address issues of energy inse­cu­rity, cli­mate change, and global envi­ron­men­tal change.

 2 | Global Change in Arid­lands – My global change research is moti­vated by the fact that over one-​​third (41%) of Earth’s ter­res­trial sur­face is arid, semi­arid, or dry-​​subhumid. Together, these water-​​stressed bio­mes sup­port 38% of the global pop­u­la­tion. Arid­lands have been iden­ti­fied as highly vul­ner­a­ble to global change-​​type threats and yet they remain vastly under­stud­ied despite their impor­tance for ecosys­tem ser­vices that humans depend on. I am inter­ested in impacts, mit­i­ga­tion, and pri­or­i­ties of global change-​​type threats on var­i­ous com­po­nents of arid­land ecosystems.

3 | Soil Ecol­ogy and Bio­geo­chem­istry – My soil ecol­ogy research is moti­vated by the fact that soils are the most under­stud­ied com­po­nent of the Earth sys­tem and yet have enor­mous impacts on its func­tion. My research seeks to under­stand the micro­bial ecol­ogy and bio­geo­chem­istry of soils, espe­cially how soil car­bon moves in soils across time and space, and what fac­tors lead to these changes. One such fac­tor includes the role of plants that form sym­bi­otic rela­tion­ships with myc­or­rhizal fungi, which in turn cre­ate vast under­ground net­works of car­bon through­out the soil ecosystem.
