33 on the Lost Coast

I had heard rumors of hidden gems and treasures, along the Lost Coast. Soon, I was turning 33, and for some reason that’s immediately where my mind went. I’m not sure what it was. October always has great surf, the solitude of the place, adventure and remoteness, who knows. The Continue reading

Datos Masivos, Ambiente y Justicia

Reposted from Uncode Cafe: http://www.uncode.cafe/inteligencias/datos-masivos-ambiente-y-justicia

Vivimos en la época y el furor de los datos masivos y la inteligencia artificial. Los datos crecen exponencialmente, y la nube – y su capacidad de análisis – se incrementa cada vez más, expandiendo sus capacidades hasta áreas que anteriormente permanecían ignoradas. Aunque tenemos hoy una muy clara noción de cómo utilizar eficazmente los datos masivos para influenciar elecciones o modificar nuestras decisiones como consumidores, todavía falta por demostrarse como los datos masivos y la inteligencia artificial se pueden utilizar efectivamente para mejorar nuestra sociedad.

Whose Hacks? Our Hacks!

Reposted from the Berkeley Energy and Resources Collaborative: http://berc.berkeley.edu/whose-hacks-hacks-takes-fight-environmental-justice-politics-climate-change/

This year Cleanweb Berkeley hosted it’s 5th annual hackathon, entitled ‘Whose Hacks? Our Hacks!’.  With previous awardees having been in information technology for flexible demand and shared solar services (and drought visualizations during the drought), we wanted to challenge participants to explore usually untouched subjects at the intersection of IT + energy and resources: environmental justice and the politics of climate change. The politics of climate change in the U.S. appear unsurmountable, and after a long slow boil, environmental justice has now reached the status of a civil rights emergency. These issues are relevant to the US and elsewhere, and we were excited to see new ideas emerge. Continue reading

Death and Garbage

Progress – what is it? Last summer I started thinking about garbage, and since then I see it everywhere, with the same story being repeated over and over again. While walking through a remote, seemingly untouched, tropical beach of Costa Rica we were awe struck to find plastic debris everywhere. Hermit crabs crawled in and around bags of chips, beer bottles, gasoline containers, plastic dolls, and styrofoam blocks. Washed down the river, thrown on the side of the road, or washed up on shore. Progress, everywhere. Heartbreaking stories ensued. In Ethiopia, gentrification and more expensive living has pushed the poor to unlivable city edges, with a garbage landslide killing 113 dump dwellers in March. In April, a methane explosion collapsed a garbage dump in Sri Lanka, burying a residential neighborhood and killing 28 people. Guatemala, China, and Lebanon have recently seen heaps of trash, plastic, and construction debris killing people, and burying homes Continue reading

SWITCHing to a Low-Carbon Future

Re-Post from National Geographic: http://voices.nationalgeographic.com/2016/02/24/switching-to-a-low-carbon-future/ 

Rolling black outs and high electricity prices were a common ritual in Nicaragua a decade ago. Schools and shops often languished for hours without power. Hotels and restaurants relied on kerosene, candles and expensive generators to keep businesses open. From a financial and health perspective, this was not sustainable. Continue reading

IDB Ideas Winners 2015

Our research project “Cool Joule: Design and implementation of a wireless sensor network to enable flexible energy loads to provide cost-effective wind energy grid integration and societal co-benefits in Nicaragua” was one of 6 winners of over 280 applications all throughout Latin America. The research partnership is between the Renewable and Appropriate Energy Lab, Niuera, Pelican, SA and the National Engineering University. The research and implementation leads were myself (Diego), Stephen Suffian (Villanova University), and Javier Rosa (Technology and Infrastructure for Emerging Regions, TIER – UC Berkeley). The videos below feature Lâl Marandin (Co-CEO of Pelican, SA – our implementation partner) and I on Canal 12, and the second video shows myself, Allan Cruz (Co-CEO of Pelican, SA), Carlos Melo (director of the Inter-American Bank in Nicaragua), and the Mexican ambassador to Nicaragua Miguel Díaz Reynoso.

Building Bridges to a Sustainable Energy Future

The Americas are undergoing a transition in the energy sector that will have global geopolitical ramifications. At the same time as the United States is touted to become the world’s largest oil producer by 2020, and a net exporter by 2030, Brazil, Nicaragua, and Panama show the most promise in becoming regional hubs not only for clean energy investment, but for sustained low-carbon economic growth (see related story: “U.S. to Overtake Saudi Arabia, Russia as World’s Top Energy Producer“).

Evidence and future scenarios of a low-carbon energy transition in Central America: a case study in Nicaragua

Published: Ponce de Leon B, D., Johnston, J., Moncada, M., Callaway, D., and Kammen, D. Evidence and Future Scenarios of a Low-Carbon Energy Transition in Central America: A Case Study in Nicaragua. Environmental Research Letters. 10 (2015) 104002

The global carbon emissions budget over the next decades depends critically on the choices made by fast-growing emerging economies. Few studies exist, however, that develop country-specific energy system integration insights that can inform emerging economies in this decision-making process. High spatial- and temporal-resolution power system planning is central to evaluating decarbonization scenarios, but obtaining the required data and models can be cost prohibitive, especially for researchers in low, lower-middle income economies.

The thermodynamics of mineral wealth, fossil fuels and drugs.

A first lesson, taken strictly from ecological economics and its use of thermodynamic laws, is very telling about the history of resource exploitation in Latin America and the Caribbean. Energy quality and energy surpluses often determine the development of social and cultural patterns, and the unidirectional character of energy can dictate the economic and social arrangements through which wealth accumulation occurs in society.1,2

Consider the unidirectional flow of water (and energy) downstream. Historically, bulky raw materials such as grains, ores, and timber were ‘produced in the hinterland and sent downstream to river mouth cities where those raw materials were combined to produce more valuable goods’.1,2 For this process of ‘upgrading’ matter into highly ordered thermodynamic structures, economic production is established, adding productive value to the economic cycle at each stage of thermodynamic progress.3-5 Great accumulations of wealth occurred in downstream cities, but very rarely did this wealth find its way back upstream. Silver from Potosi (Peru) and Guanajuato (Mexico), gold from Ouro Preto and Minas Gerais (Brazil), sugar cane from Cuba, coffee from Colombia, precious woods (and later sugar) from the Caribbean, and bananas and fruit from the entire Western Hemisphere were sent to the United States and Europe. Resource wealth flowed in one direction, fostered industrial growth in the north, and created a Latin American and Caribbean dependence for technology and goods produced in the industrial north.6-8

More recently it is rare earth metals, oil, and drugs that flow downstream.
