Clean energy needs may cause years of high prices for copper, nickel, cobalt, and lithium under a net-zero emissions scenario.

The world’s historic pivot toward curbing carbon emissions is likely to spur unprecedented demand for some of the most crucial metals used to generate and store renewable energy in a net-zero emissions by 2050 scenario.

Prices could reach historical peaks for an unprecedented length of time—and even delay the energy transition itself.

A resulting surge in prices for materials such as cobalt and nickel would bring boom times to some economies that are the biggest exporters—but soaring costs could last through the end of this decade and could derail or delay the energy transition itself.

Prices for industrial metals, an important foundation for the global economy, have already seen a major post-pandemic rally as economies re-opened, as we recently wrote. Our latest research, included in the October World Economic Outlook and a new IMF staff paper, details the likely effects of the energy transition for metals markets and the economic impact for producers and importers.

For example, lithium, used in batteries for electric vehicles, could rise from its 2020 level around $6,000 a metric ton to about $15,000 late this decade—and stay elevated through most of the 2030s. Cobalt and nickel prices would also see similar surges in coming years.

Zimbabwe is one of the African countries that hopes renewable energy technologies will help to address their energy problems. About 42% of Zimbabwe’s households are connected to the electricity grid.

The country has huge and diverse renewable energy potential. Its sustainable energy portfolio could include solar, hydro, biomass and, to a limited extent, wind and geothermal. Zimbabwe put forward a National Renewable Energy Policy in 2019. The policy aims to have 16.5% of the total generation capacity (excluding large hydro) from renewable sources by 2025. This increases to 26.5% by 2030. These are among the goals it has presented to the United Nations Framework Convention on Climate Change and they are promoted in its climate policy.

For policy makers, non-governmental organisations, the private sector and some researchers, it’s a given that renewable energy technologies are the answer. They could meet Zimbabwe’s growing energy demand and achieve universal access sustainably. At face value this is appealing – but the devil is in the details.

My research looked into how renewable energy technologies are understood and how they could alleviate energy poverty in Zimbabwe.

I found that they’re only one piece of the puzzle and other pieces are habitually missing. No matter how well designed and efficient technologies are, their effectiveness is linked to the country’s political economy.

Socio-economic and political factors keep conventional energy out of reach of the poor. My study shows that they can do the same with renewable energy. These factors may even worsen inequality. Adding renewable energy technologies into the existing energy sector structures is like pouring new wine into old wine skins.

The research

I analysed how policy makers and implementers have highlighted some aspects of energy poverty rather than others. This has led to renewable energy being touted as an antidote to energy poverty.

From the data, the following political and economic factors emerged. They explain why renewable energy isn’t a magic bullet for energy poverty:

The politics of energy and technological dependency: China has become a source of finance for large-scale energy projects in Zimbabwe. This is true for both coal-based and renewable energy generation.

Abstract

Energy poverty is well acknowledged in the global public and scholarly discussions. Nonetheless, it is habitually analysed in isolation from the discourse through which it is framed, produced, represented and known. Using Zimbabwe as a case study, inductive qualitative research reveals that there is one main discourse associated with energy poverty: net deficit (supply–demand mismatch). This discourse is expressed by narratives that have competed for dominance in the Zimbabwean energy sector (2012-present), in particular, the effect of changes in the climate, vandalism of electricity infrastructure, the impact of sanctions, and the low rate of renewable energy adoption, are analysed. Findings reveal that these narratives construct and interpret energy poverty as an outcome of external factors, while alternative views are scarcely considered due to asymmetrical power relations. The paper concludes that energy poverty cannot be understood outside of the political-economic discourse that constructs and interprets it. Hence, a discursive approach to energy poverty is apt for informing a well-balanced energy policy and practice.
