The State of Energy

Material dimensions of “dirty” renewables in Mauritius

  • Jessica Caporusso

When you flick on a light switch, what do you see? What is happening? Depending on where you are in the world, the electricity illuminating that lightbulb in front of you comes from a particular aggregate of energy sources. If you hail from southwestern Ontario, the energy mix is likely to be a combination of nuclear energy, hydroelectric, wind, natural gas, and miscellaneous renewables including solar and biomass.1 If you find yourself in the small island developing state (SIDS) of Mauritius in the western Indian Ocean, that mix is more likely to be composed of non-renewable energy sources (79%), mostly derived from imported coal and natural gas, and renewable sources (21%), mainly in the form of locally grown sugarcane biomass and its discards.2

Electricity is often perceived to be an ephemeral, fleeting substance, and thus difficult to study; it is transient, instantaneous, and notoriously elusive to pin down.3 However, as several energy scholars have recently elucidated, electricity—along with its production and its discards—is materially grounded in particular histories and political geographies.4 Where and how energy is produced matters.

In Mauritius, the local energy supply depends on a socially combustive5 mix of fossil fuels and renewable energy sources drawn from seemingly fixed, material landscapes. One such energy feedstock, bagasse—a fibrous byproduct of the island’s sugarcane industry and derivative fuel used in colonial-era sugar processing—is in the process of being converted into a modern, sustainable biofuel feedstock. This move is driven by the government’s desire to decrease dependency on foreign fossil fuels while capitalizing on increasing demands for a local, sustainable biofuel economy.6 Mauritian state-owned agencies and private enterprise, in particular, have also pushed for local green-energy solutions in line with governmental dreams for national energy security fueled by renewable energy sources. At present, approximately sixty-six percent of the island’s total energy mix comes from combination of bagasse and coal combustion produced by the country’s four sugar-millers turned power-producers, each managing its own thermal power station.7

Although the ready availability of sugarcane discards makes bagasse an appealing energy feedstock, the success story of byproduct-to-fuel source is not as green as it is purported to be. While energy generated from bagasse seemingly “recuperates” value from waste, this process obscures bitter histories of sugarcane plantation labour and the energy extracted from enslaved peoples forced to farm it.8 So, how does sugarcane, a commodity crop rooted in colonialism, become converted into a driver of economic growth bound up in dreams of sustainable development?

In order to understand how a nascent green energy sector is shored up by plantation economies, it is imperative that we turn our attention to the material dimensions of power and waste. Discard studies scholar Max Liboiron, in particular, has called attention to the importance of studying systems of waste and wasting as social, economic, and political problems, as opposed to technocratic ones.9 Using the analytic of “discarding” instead of waste or wasting, Liboiron further draws attention to the ways that wasted materials, as well as “people, landscapes, futures, [and] ways of life,” are also made expendable as matter-out-of-place,10 or matter not readily available for capitalist extraction.

One small story may unearth the rippling effects of such complex relations. In the summer of 2016, in the midst of my doctoral research on “green” energy transitions, I was invited to participate in a Plant Propagation training workshop at the Mauritius Sugar Industry Research Institute (MSIRI). Aimed at budding horticulturalists and retirees, the workshop taught plant grafting techniques, as well as how to care for local varietals and the proper handling of gardening hormones and equipment. During our leisurely tea breaks, I had cultivated a relationship with Michel, one of the long-term administrative staff members, who during tea one day, shared the story of the program’s origins. “You know,” he explained, “at the outset, this program used to be for sugar labourers. It was to retrain them after [the sugar industry] ‘restructuring’…[it wasn’t] for hobbyists.”11 In other words, labourers had been made “redundant” through industry downsizing and needed to be reskilled for other sectors. Such stories are not singular occurrences in Mauritius.12

Submerged in the story of sugarcane are enduring legacies of exploitation, extraction, and discarding. Imagine the intertwined histories of global capital, slavery, and indentureship that terraformed an island thick with endemic ebony wood into mono-crop sugarcane plantation economies. As a thrice-colonized sugar plantation enterprise and enduring sugar producer, Mauritius shares with the Caribbean a long history of raw material production at the service of industrial capitalism.13 The original inhabitants of the island, the ill-fated Dodo bird, were displaced by circulating flows of similarly displaced peoples through processes of enslavement and indenture that were woven into the very fabric of Mauritian society.14 What violence, injuries, uprootings, and upheavals were met out in order for such “Plantationocene” logics to take form?15 What livelihoods and ways of living where discarded to make way for this system? What uprootings continue to take place?

Current systems of power extraction do not break from past colonial enterprises, but rather shore up them up. As Christina Sharpe contends, “in the wake, the past that is not past reappears, always, to rupture the present.”16 For Sharpe, being “in the wake” means a mourning of, but also reckoning with, the rippling effects of an enduring, far-reaching colonialism; that is, a colonization that does not end with a formalized decolonization but submerges and resurfaces over time. Drawing on anthropologist Michel-Rolph Trouillot,17 Sharpe highlights the ways that the “past” has not passed. Being in the wake is a matter of holding to account how colonialism’s effects reverberate through time, amplifying the enduring injuries against enslaved peoples, their descendants, and colonized environments on a planetary scale.

In moments of such resurfacing, what does it mean when “green” energy systems are built upon the enduring legacies of indentured and enslaved peoples’ labour?18 For Mauritian labour activists and environmentalists, sugarcane’s dirty past greatly problematizes its potential as an ecological and socially viable source of power. Green energy cannot be socially “sustainable” if it is founded upon systems of exploitation and extraction—systems, that in turn, maintain sugar barons’ hold on power. In other words, shoring up a contemporary “green” energy industry in Mauritius cannot be disassociated from plantation forms of power. As Mauritius comes to grips with its energy future, what counts as “sustainable” practice matters. To redress these concerns, several labour and energy activists in Mauritius have aimed to disconnect renewable energy feedstocks from any association with colonial exploitation, specifically wresting it from the control of former sugar baron families—some of whom presently run the sugar mills-turned-thermal power plants in Mauritius.

At present, several environmental groups and labour networks are attempting create more livable futures. Some argue that sugarcane and its discards cannot exist as a socially just, “sustainable” energy feedstock.19 The way forward, instead, lies in environmental justice initiatives such as solar energy cooperatives. Other interlocutors have noted that solar energy panels are cost-prohibitive and therefore unattainable for the vast majority of Mauritians.20

Other activists and industry-stakeholders have argued that bagasse can be an important transitional fuel source that supports smallholder farmers’ livelihoods—and their knowledge—while responsibly utilizing plant discards for energy consumption. In these disagreements, we find underlying refusals21 to accept common, fixed understandings of sustainable energy forms—differences that have much to teach us about the contingencies and contexts of power.

Jessica Caporusso is a PhD candidate in the Department of Anthropology at York University. Her research interests meet at the intersection of political ecology, bioenergy, and discard studies. Her dissertation examines how “waste”—as an externality and as resource—is defined through neocolonial logics, by investigating the transformation of crop residues into biofuel feedstock in the small island developing state of Mauritius. Jessica’s work explores the multiple and contested meanings of waste and value while also tracking the development of bioenergy as a source of energetic, political, and economic power. She is an active contributor to the Plant Studies Collaboratory and the Energy Working Group at York.
