As winter approaches, reminiscences of the previous hang-out South Africans in additional methods than one. The nation has skilled years of rolling blackouts, identified regionally as load shedding. Throughout the worst intervals of those energy cuts in 2022 and 2023, South Africans who didn’t personal photo voltaic photovoltaic methods or mills would go with out electrical energy for up to 12 hours a day.

Because of the extent of the damaging power outages, solar power was adopted rapidly in South Africa. For instance, in 2020, smaller methods put in at houses or companies made up simply 38% of the nation’s photo voltaic methods. At the moment, 62% of photo voltaic methods have been utility-scale solar energy. (These included massive photo voltaic farms that feed electrical energy straight into the nationwide grid.) However by Could 2024, the share of smaller solar energy methods had shot as much as 74%, far more than that of utility-scale photovoltaic methods.

As a crew of researchers specializing in mapping, geography, and renewable energy transitions, we observed that satellite imagery confirmed that some components of South Africa have been nonetheless brightly lit at evening, even throughout energy cuts.

We wished to search out out if this was as a result of these areas have been exempt from energy cuts or if it was as a result of they’d switched to various energy sources.

So we in contrast publicly out there nighttime satellite tv for pc photos of 300 suburbs with satellite tv for pc photos of South African rooftops taken throughout the day. We appeared on the photos for each day and evening between 2016—when there have been nearly no energy cuts—and 2023, when energy was minimize for nearly 79% of the yr.

The satellite imagery revealed that nighttime mild declined by 20% over city South Africa between 2016 and 2023. Nonetheless, some suburbs remained curiously brilliant even when the ability was out.

We overlaid the satellite tv for pc photos with nationwide census maps and located that areas the place predominantly Black residents lived darkened twice as a lot throughout this time as predominantly white suburbs.

There have been nearly zero photo voltaic panels in impoverished areas, whereas rich suburbs have been plush with rooftop photo voltaic methods.

This mirrored the spatial divisions established underneath apartheid—that’s, the geographic divisions established underneath South Africa’s former system of racial segregationthe place folks have been forcibly separated into totally different areas primarily based on race.

Our study shows that whereas photo voltaic vitality adoption is booming in South Africa, it’s largely benefiting wealthier, white communities. We consider we’re seeing proof of energy apartheid—entry to vitality that also follows the racial divisions created by apartheid.

Which means the federal government must take steps to guarantee that the inexperienced vitality transition advantages everybody equally. With out rolling out renewable vitality to all, inequality will deepen and hundreds of thousands of individuals will probably be left at the hours of darkness.

Who will get to maintain their lights on?

South Africa’s Electricity Regulation Act goals to make sure that everybody can entry electrical energy on an equal foundation. Nonetheless, there isn’t any public information on whether or not the ability utility Eskom’s energy outages are extra extreme in some areas, or not. This meant we couldn’t confirm whether or not energy cuts have been taking place pretty and equally throughout all suburbs.

As a substitute, we tried to search out out who will get to maintain their lights on through the use of daytime satellite tv for pc photos from 300 suburbs for the seven years between 2016 and 2023. These confirmed us which communities had essentially the most houses with rooftop photo voltaic photovoltaic panels.

For instance, within the high-income Rietriver Nation Property close to Johannesburg, a median of 13 photo voltaic panels have been detected per home. A middle-income suburb within the city of Benoni, the place residents earn half as a lot, has a median of 1 photo voltaic panel per family. And in Thembisa, a low-income space the place residents earn a median of R740 (US$41) per individual per 30 days, not one photo voltaic set up was recorded within the space, highlighting the stark distinction with wealthier suburbs.

We discovered that the variety of photo voltaic methods in predominantly white suburbs was 73 times higher than in areas that primarily home racial groups who have been beforehand deprived by apartheid.

What must occur subsequent

Our findings are typical of the extremes of energy injustice within the world south. Right here, transferring from coal-fired energy to cleaner, renewable vitality does not remedy the issue of vitality poverty (the place vitality is concentrated amongst extra prosperous folks).

As a substitute, the inexperienced vitality transition amplifies social inequality. Our examine highlights the danger that South Africa’s transfer to cleaner vitality may make long-standing inequalities even worse. But it surely additionally factors to methods of overcoming them:

For these measures to work, they have to be co-designed with numerous stakeholders. They need to deal with the precise wants and aspirations of South African households.

For the inexperienced vitality transition to be inclusive and sustainable, conversations round renewable vitality ought to think about who can entry and profit from solar energy.
