Building a New Economy on Soda Bottles and a 3D Printer

On a steep road on the outskirts of Oaxaca de Juárez, Mexico, a low buzz and plastic fumes emanate from a white house. A ribbed white paper tube snakes out of a window on the building, exhaling a light smoke which mixes with fumes from nearby open-air cooks and the sooty exhaust of rumbling, unmuffled bus engines. Inside, the tube is attached to a machine that’s gobbling plastic flakes—which can come from used drink bottles—through a funnel also made from a plastic drink bottle. At the other end of the machine, a spinning wheel draws out the fresh-melted polymer into a black filament just three millimeters wide and value hundreds of times what it was worth in in bottle form.

Mexico’s Renewables Revolution Creates Tension

Men died in gun battles over the installation of windmills in the state of Oaxaca, Mexico, three years ago. Opponents argued that energy companies misled them and that community leaders rented out collective lands without consulting everyone they should have. Today, protests continue, but the growth of wind farms and other renewables seems assured: Mexico boasts almost 2 gigawatts of installed wind power capacity and plans to install perhaps another 12 GW by 2022. All that clean energy is a big change for this country, which is the world’s ninth-biggest oil producer and perhaps the 11th-biggest emitter of carbon dioxide. Continue reading

Power Production Decentralizes in Mexico

Over the last twenty years, Mexico’s electricity sector has shifted from being almost 100 percent state-owned and centralized to about one quarter privately generated. This summer, the Mexican government signed into law energy and electricity grid reforms that will accelerate the decentralization of its electricity production (See “Mexico Opens Its Grid to Competition.”). By the end of this year, a new agency should have a regulatory map available for power producers large and small, said Edgar López, renewable energies director at Mexico’s Energy Regulatory Commission (CRE) at a conference in Mexico City last month.

Mexico Opens Its Grid to Competition

As part of a wider reform of its energy market, Mexico is privatizing its energy regulator and will begin allowing private companies to sell energy to, and add capacity to, its electricity grid. The country’s president, Enrique Peña Nieto, enacted the laws (English summaries) on Monday, August 11th (Spanish pdf). Petroleum and electricity have been state monopolies in law since the 1917 constitution and in practice since the late 1930s, when Mexico succeeded in expropriating foreign energy firms’ holdings.
