How America’s Closets (And Sometimes Runways) End Up in Mexico’s Markets

By Kary Vannice—

Whenever I travel to a new town in Mexico, the very first thing I look for is the local tianguis market. Some people go straight to the beach or the zócalo, but I make a beeline to the used clothing stalls. There is something irresistible about those long rows of tarps and huge piles of clothing, each one holding the possibility of an unexpected treasure.

Over the years, I have found everything from soft cashmere sweaters for eighty pesos to high-end dresses like Prada and Kate Spade with the original tags still attached for under ten dollars. And every time it happens, I feel the same spark of excitement and disbelief. How did this piece, so clearly meant for a very different kind of clientele, end up here amongst the street tacos, veggies, and chingaderas?

To me, it feels like fashion magic. But what feels like magic is actually part of a far bigger story, one that starts far from Mexico’s markets and reveals a great deal about the way clothing moves around the globe.

Most people in the United States believe that when they donate clothing, it ends up hanging neatly in a thrift store, ready for a new owner. The truth is very different. Only a tiny fraction is ever resold in the U.S. More than half is bundled, compressed and shipped out of the country. Mexico happens to be one of the main destinations.

Every year, the United States exports millions of tons of used clothing. Much of it from discount retailers, thrift stores or big box stores. But you can also find unsold inventory from more upscale stores, last season’s corporate clear outs and even brand samples that never make it onto the market. A well-used T-shirt from Walmart and a designer sale sample can all end up in the same enormous stream of “fashion waste”.

Arriving in Mexico as tightly wrapped bundles known as “pacas” and sold as “Ropa Americana”, they look a lot like plastic hay bales stuffed to bursting with mostly used (but sometimes new) clothing. Vendors buy them unopened, relying on codes stamped on the plastic to guess what might be inside. A paca can hold anything from children’s sweatshirts to high quality outdoor jackets to a dress from a designer brand that never made it past the showroom. And for many families, these bales are not just bundles of clothing. They are income, opportunity and a monthly gamble they hope will pay off.

Once something enters this bulk resale circuit, it follows its own path. A single sample blouse worn once for a catalog shoot can travel thousands of kilometers and eventually land in a street market in Oaxaca, Queretaro, or Mexico City.

The Mexican tianguis shopping experience reveals something important about fashion and culture. And that is, this humble community marketplace treats all clothing the same. In the United States fashion is organized by price, privilege, and status. Here, everything becomes just another piece of clothing again. A four-thousand-dollar designer suit jacket can be found under a faded tank top from Target. Here, the fashion hierarchy completely breaks down and a shirt is simply a shirt.

This unseen migration of clothing from the US to Mexico also reflects a bigger picture. Clothing doesn’t just disappear when one person is done wearing it. It continues its journey. It moves between countries, homes, economies, and cultures. What one society considers used or outdated becomes valuable in another context and community.

In our world, discarded clothing operates as a global supply chain of waste, resale, redistribution, and revaluation. It serves as a reminder that, in fashion, value is fluid, movement is constant, and our world is far more interconnected than it appears. Here in Mexico, the tianguis culture gives us a front-row seat to something most people never see, how global waste becomes local value, and how communities creatively reshape what the world throws away into income, opportunity, and economy.

Mexico’s Energy Crossroads: Can Sunshine Power the Future?

By Raveen Singh

How does Mexico keep the lights on? Unlike Canada, which generates most of its electricity from clean, renewable hydro power, Mexico relies heavily on fossil fuels. Hydroelectric opportunities are limited by topography, rainfall, and geography. As a result, natural gas has become Mexico’s workhorse — providing about 59% of the country’s electricity between August 2024 and July 2025.

Renewable sources — hydropower, solar, and wind — now supply roughly a quarter of Mexico’s power. While progress has slowed in recent years, the potential for alternate, cleaner, more secure energy remains enormous.

Where Mexico Gets Its Power

The Federal Electricity Commission (CFE), the state-owned utility, still dominates the sector. It is the only electricity provider for small and medium consumers and is legally required to maintain 54% of national power generation. Its mandate is to ensure stability in the National Electric System, but this dominance has made it difficult for private or foreign investors to enter the market.

Mexico’s National Electric System Development Program sets a bold goal: 50% clean energy by 2050. The vision is ambitious — the country’s geography offers abundant sunshine and strong winds — but the reality is more complicated. Recent policy shifts have favored fossil fuel expansion and reduced incentives for renewables. This has caused a slowdown in new solar and wind projects and concern among investors watching Mexico’s energy transition stall.

Hydropower: Limited by Landscape and Public Opinion

Hydropower may be clean and inexpensive once built, but it requires very specific conditions: a combination of terrain, consistent rainfall, and suitable geological foundations, work together for a viable project. Mexico’s geography and climate offer limited opportunities for such large-scale projects. Even where feasible, public opposition often arises over the flooding of valleys and the displacement of communities, not to mention historical land ownership issues that are prevalent.

Large dams also take years — sometimes decades — to plan and fund. A good example of how megaprojects can attract political interference and public distrust is seen with Canada’s SNC-Lavalin corruption scandals in the early 2000s.

Smaller “mini-hydro” installations have been developed across Latin America to minimize environmental impact, but they come at higher costs. Polaris Renewable Energy Ltd., a publicly-traded Canadian company operating in the region, shifted its focus toward solar after finding hydropower and wind developments slow and bureaucratic, as well as expensive and with a higher environmental disruption. As their executives put it, solar projects are simply faster, cheaper, and easier to deliver.

Wind Power: Promise in the Isthmus

Mexico’s southern Isthmus of Tehuantepec is among the windiest corridors in the Americas, making it the natural home for wind generation. The country currently has 87 onshore plants producing 8.67 GWh, with another 13 projects under construction. Yet few new ones are planned or approved.

The challenges are both technical and financial. Wind farms must be designed to withstand hurricanes and tropical storms — risks that drive up insurance and construction costs. Irregular wind patterns mean projects require storage or backup generation. Battery technology is improving but remains expensive and imperfect. And as climate change increases the unpredictability of weather patterns, long-term investors grow cautious.

For now, Mexico’s wind sector remains viable but uncertain — full of potential, short on momentum.

Solar Energy: The Bright Side

The clear winner in Mexico’s renewable race is solar power. With 85% of the country enjoying ideal conditions, sunlight is Mexico’s most abundant resource. Solar energy has expanded dramatically, from just 0.18 GW of installed capacity in 2016 to nearly 12 GW by 2024 — supplying 7.6% of national electricity.

Massive facilities such as the Villanueva Solar Plant in Coahuila (754 MW) and the Puerto Libertad complex in Sonora (405 MW) have positioned Mexico among the world’s leading solar power producing nations. If expanded strategically, solar power could meet more than half of the country’s energy demand within the next decade.

The benefits are obvious: reduced dependence on imported natural gas, lower emissions, and greater energy security.

The Obstacles to Going Solar

So, what’s holding Mexico back?
Despite its potential, building solar farms in Mexico costs more than the global average. Financing is expensive, supply chains are underdeveloped, and grid infrastructure is aging. Much of the national transmission system lacks redundancy, meaning a single failure can leave entire regions without power — as the two-day blackout across Yucatán and Quintana Roo in September 2025 demonstrated.

Solar power also requires major investment in energy storage to balance generation during cloudy days or nighttime hours. Without large-scale batteries and modernized transmission, much of Mexico’s sunshine will remain untapped potential.

Another challenge is policy. While the 2013 constitutional reform opened the energy sector to private and foreign investment, subsequent administrations have reasserted state control. This has made Mexico less attractive to international investors, even as global capital for renewables has surged elsewhere in Latin America.

Acciona: A Case Study in Renewable Investment

Spanish contractor Acciona Energía has been one of the most active foreign developers in Mexico, operating both wind and solar projects and building transmission infrastructure for the CFE. The company’s portfolio includes the 183-MW El Cortijo and 138-MW Santa Cruz wind farms in Tamaulipas, four wind projects in Oaxaca totaling over 550 MW, and the 405-MW Puerto Libertad solar complex in Sonora.

Acciona has also supported rural electrification through its non-profit arm, acciona.org, providing solar power to remote communities in Oaxaca and San Luis Potosí.

Yet even Acciona has signaled uncertainty. In August 2025, it announced a review of its entire Mexican portfolio as part of an “asset rotation process,” citing a tougher business environment. For Mexico — once considered a regional renewable leader — this retreat is a worrying sign.

The Road Ahead

Mexico has pledged to reach 45% clean energy by 2030 and 50% by 2050. Achieving that will require streamlined permitting, modernized transmission lines, and predictable policy to attract both domestic and international investment.

Experts agree the sun offers Mexico its brightest opportunity. But technology alone isn’t enough — political will must align with the nation’s natural advantages. A modern, reliable grid could make Mexico a continental powerhouse of clean energy.

Until then, the country stands at an energy crossroads: one road leading deeper into fossil fuel dependence, and another toward a self-sustaining, solar-powered future.

Mexico’s Green Energy -Potential, Promise, Problems

By Randy Jackson

POTENTIAL

Few countries on earth have such an abundance of green energy potential as Mexico. The geography and geology of Mexico provides three substantial sources of green energy: solar, wind and geothermal.

Solar: Potential energy from solar projects seems obvious, with much of the country bathed in sunlight for a good portion of the year. Also, the lower the latitude, i.e., the lower the distance from the Equator, the higher the energy concentration of the sun. The northwest area of Mexico has the highest average number of days of sunlight in the country. The sunniest spot on earth is just north of Mexico, in Yuma, Arizona, and the surrounding areas stretching well into Mexico have a very high average number of days of sunshine. Days of sunshine, concentrated by lower latitudes, end up in a measurement called “insolation.” Insolation is a measurement of kilowatt hour per square meter, essentially a measurement of sunpower at a given location. All this leads to the calculation (using existing solar panel efficiency) that just 25 square kilometers of solar panels, were they located in the Sonoran Desert or the state of Chihuahua, would be sufficient to provide 100% of Mexico’s electricity demand.

Wind: Many of us who are familiar with Huatulco and the surrounding area know of the substantial wind energy facilities in the narrower part of the Isthmus of Tehuantepec. The Eurus Wind Farm in Juchitán de Zaragoza is the largest wind farm in Latin America. In Mexico overall, the states of Oaxaca, Yucatán and Tamaulipas all have locations with average wind speeds greater than 28 km/hour – 15 Km/hour is the minimum average speed normally required for a wind farm. Average wind speed is one determining factor for wind farms; the other is air density. Sea level locations, as at the Eurus Wind Farm, have higher air density when compared to higher elevations. This means the air has more mass, essentially giving the wind more power to turn a wind turbine. REVE, the Spanish wind energy magazine, reports that Mexico has wind energy potential of about 70,000 MWH (megawatt hours), about the total current electrical generating capacity in all of Mexico.

Geothermal: Mexico has 48 active volcanoes, a testament to the high degree of tectonic activity below the earth’s surface in Mexico (has anyone not experienced an earthquake in Huatulco?). Geothermal resources are most often found along tectonic plates where the earth’s magma is closer to the surface. This superheats rock that can be easily drilled into from the surface; water is then injected and the resulting steam drives turbines to create electricity. The world’s second largest geothermal power station is located in the state of Baja California, near the city of Mexicali. This location, known as Cerro Prieto, sits atop of a unique geological fault usually only found under the oceans. The Mexican ministry of energy envisions 1,670 MWH of electricity from geothermal plants by 2030.

PROMISE

Before hosting the 2010 United Nations Climate Change Conference in Cancún, Mexican President Felipe Calderón set out goals for Mexico to reach one-third of its energy from renewables by 2024. Some reforms and laws were initiated in Calderón’s term of office to move towards these renewable energy goals. In Mexico, energy is state owned and controlled.

Energy resource ownership, particularly oil but also electricity generation, is a sensitive national concern for Mexico. However, in 2013, President Enrique Peña Nieto was able to pass a reform that allowed private companies to participate in the energy sector, with the control, transmission and distribution of energy remaining exclusively within the control of the state. This initiative, followed up with specific regulations, allowed private investments in renewable energy projects to recover their investments over time, by selling electricity to the state owned CFE (Comisión Federal de Electricidad) under negotiated contracts.

These reforms and Mexico’s abundant green energy potential allowed many Mexican and international companies to step forward to propose and develop green energy projects. To facilitate these projects under state control, Mexico held three auctions to purchase renewable electricity under long term contracts; 41 projects were selected under the auction process. Solar energy projects accounted for 4,867 MW, wind energy 2,122 MW and geothermal 25 MW. In 2017 private investment in renewable energy in Mexico was $6.2 billion USD. Mexico seemed to be off to a good start towards its green energy goals.

PROBLEMS

In 2018, President Andrés Manuel López Obrador (often referred to as AMLO) was elected. Shortly after taking office, AMLO cancelled any future auctions to purchase green electricity by CFE. Then, in early 2020, under the guise of COVID-19 measures, Mexico changed the rules of how wind and solar projects could access the electrical grid. The new policy imposes a new requirement on developers of wind and solar projects to obtain a generation permit. These permits are subject to further regulations that prioritize CFE electrical generation from oil and gas electricity plants. These changes have raised international concerns regarding regulations that effectively cancel existing legal contracts. The European Union sent a letter to Mexico’s Energy Minister, Rocío Nahle García, saying the new rules would negatively impact 44 renewable energy projects and jeopardize $6.4 billion (USD) in renewable energy projects from EU companies. Bloomberg News reported March 16 of this year that the Canadian government expressed concern to the Mexican Economy Secretary, Tatiana Clouthier Carrillo, about stranding a potential $4.1 billion (USD) in renewable projects by Canadian companies. These concerns have also been expressed by the US and other countries using diplomatic channels.

The arguments made by the current Mexican administration in defending their change to regulation regarding private investments in the electrical energy grid are numerous. AMLO has suggested that corruption was involved in awarding some of the contracts to purchase electricity. He has also argued that the sporadic nature of renewable energy destabilizes the electricity grid. He also said there is just too much bureaucracy overseeing the energy sector in Mexico, and more central control is needed.

Some of these regulatory changes are currently being challenged in Mexican courts, so the final outcome is yet to be determined. However, the substantial green energy potential of Mexico is out there, available, awaiting the right political conditions for it to be harvested.
