Nigeria’s presidential villa is being kitted out with a $6-million solar mini-grid – a pricey solution to erratic power supplies that small business manager Victor Onyim can only dream of as he grapples with near-daily power cuts.
For more than two weeks until early May, Onyim’s drinking water company and other businesses in the southern city of Port Harcourt struggled to keep operating due to a total blackout blamed by the local power utility on vandalism. It has since been resolved, but regular outages continue.
“The lack of light (electricity) is affecting our business. We have not been making sales since the power issue,” he told Climate Home, gesturing towards the half-empty stock room and idle delivery trucks parked at the front of the plant in the country’s oil-rich Niger Delta region.
To keep the business afloat during the recent outage, Onyim spent 30,000 naira ($18) daily on diesel and was forced to halt production at midday to reduce the fuel bill, sending workers home early.
“Substituting the light from the grid with generators … is better than not having light at all,” he said.
Generators far cheaper than solar
The whirr of generators is a common sound in Nigeria, where the national power grid is prone to frequent failures, plagued by creaky and poorly maintained infrastructure despite repeated pledges by governments over the years to tackle it.
While those who can afford it are starting to install solar panels and storage batteries to bypass grid supplies, poorer Nigerians have no option but to stretch household budgets to buy fuel – to supply generators – kerosene lamps and candles for lighting and bottled gas for cooking.
Petrol and diesel generators remain the favoured alternative for power generation. While the fuel is an extra running cost, a small petrol generator can be bought for as little as 120,000 naira ($74).
It costs roughly five times more than that – 600,000 naira ($323) – to buy just one solar panel with an inverter battery. The minimum monthly wage in Nigeria is 70,000 naira ($45).

Leapfrogging straight to renewables
In much of Africa, where an estimated 600 million people still have no access at all to mains electricity, leapfrogging straight to solar power would boost power access while also reducing the need for fossil fuels such as natural gas, oil and coal to generate electricity.
Nigeria’s power sector is heavily reliant on fossil fuels, with gas accounting for over three-quarters of electricity generated in 2022, hydropower delivering about a quarter, and renewables less than 1%.
But high solar system installation costs are a huge hurdle, particularly in the poorer rural areas that would stand to gain the most – access to electricity, in many cases for the first time.
Almost half of Nigeria’s roughly 230 million people live without access to electricity from the grid – making it the country with the highest number of people lacking it globally.
Even for those who are connected to the grid, dilapidated transmission infrastructure, vandalism and inadequate maintenance resources mean the supply is unreliable, raising the appeal of self-contained solar systems – even for the country’s leader.
In Nigeria, Zimbabwe and South Africa, solar booms have been driven by power cuts prompting those who can afford to invest in reliable solar electricity. However, this is usually a fraction of the majority. The 2025 Africa Solar Outlook report found that commercial and industrial users made up a large part of the installations in 2024.
Renewables for the rich?
With few signs of improvement in Nigeria’s power supply, civil society campaigners have criticised the government’s approval of the multi-million-dollar solar system at the sprawling Aso Rock presidential residence in the capital, Abuja.
A spokesperson for President Bola Tinubu said the initial investment would soon be clawed back through savings on electricity bills.
Indigenous land disputes cloud Kenya’s carbon market ambitions
But solar for the rich, and government officials, is not the equitable shift to greener electricity that Africa’s policymakers should be working to implement, said Joshua Alade, founder of Network of Youth for Sustainable Initiative, a youth-led civil society organisation based in Nigeria.
“This current trend of renewables being accessible mainly to the affluent is far from what we advocate for,” Alade said, adding that government efforts to foster renewable energy must focus on vulnerable communities “historically left behind by traditional energy systems”.
Nigeria’s power crisis perpetuates deep economic inequalities in Africa’s most populous country, with smaller businesses and micro enterprises like Onyim’s in Port Harcourt less able to cope with the blackouts.
According to estimates by the World Bank, unreliable electricity supplies cost the Nigerian economy $29 billion a year.
Clean energy investments are growing – slowly
Investments in renewable energy in Africa are growing, but too slowly to put the continent on track to reach its sustainable development goals, according to the International Energy Agency (IEA).
Clean energy investments in Africa account for just 2% of the global total, the IEA said in its latest World Energy Investment Analysis report, adding that as they stand, energy investments are equivalent to only 1.2% of the region’s gross domestic product (GDP).
Efforts to tackle Africa’s power access gap, and boosting renewable energy generation at the same time, are the focus of initiatives such as Mission300, a joint effort of the African Development Bank (AfDB) and the World Bank.
The programme, which aims to get power supplies to 300 million people – half of the number without electricity access in Africa – by 2030, raised over $50 billion in pledges of support earlier this year at a meeting in Dar es Salaam, Tanzania.

Ensuring green power shift benefits all
For the initiative to succeed where others have failed, Nigeria-based energy expert Teslim Giwa said African governments must place greater emphasis on the economic benefits of improving – and widening access to – electricity.
In order to ensure lower-income communities are reached, he called for policies including subsidies on products such as solar panels and batteries for storage and discounted electricity bills for the poorest people.
Community ownership of clean electricity initiatives – for example, solar mini-grids in neighbourhoods – should also be promoted, Giwa said, adding that the approach would help prevent vandalism and stop infrastructure falling into disrepair.
Back in Port Harcourt’s Rumuokwachi district, not far from Onyim’s water packaging plant, welder Bright Azuka hunches over a steel gate, sparks flying as his welding machine crackles to life.
The hum of a generator can be heard in the background as he works swiftly, racing to finish a job before it runs out of fuel. Azuka spends 10,000 naira ($7) per day on petrol so he can carry on working during power outages.
He urged President Tinubu’s government to find ways of making solar systems more affordable for ordinary Nigerians like him.
“Even though I don’t have electricity here, I am paying monthly bills,” he said. “It’s not easy.”

Q&A: How can African electricity access power jobs not just lightbulbs?
At the African Development Bank (AfDB) annual meetings this week, several African leaders called for investments in electricity infrastructure which go beyond lighting homes to powering economies.
Applauding the AfDB for its energy programmes like Mission 300 – which aims to provide electricity access to 300 million Africans by 2030 – the Central African Republic’s President Faustin-Archange Touadera said that without power supply “we will not be able to achieve development”.
Speaking alongside him, the Republic of Congo’s President Denis Sassou Nguesso echoed this, saying that “as we need to help our people to turn towards agriculture, to turn towards livestock rearing, we also need to provide power to them.”
As the Mission 300 initiative advances, attention is increasingly shifting from simply connecting households to ensuring that electricity access translates into economic opportunities and livelihoods. That shift is driving the launch of a new Centre of Excellence for Productive Use of Energy being developed under Mission 300 by the philanthropically funded Global Energy Alliance for People and Planet (GEAPP).
In an interview with Climate Home News, Carol Koech, GEAPP’s vice president for Africa, said the initiative is designed to ensure that electrification supports income generation, agriculture and local economic development rather than only basic household access.
Q: What is the Centre of Excellence for Productive Use of Energy aiming to achieve with Mission 300?
A: Mission 300 is increasingly being seen as a job platform and so the role of the Centre of Excellence in translating those electricity connections to jobs. So we want the centre to do four things. First, as a delivery engine, which enables countries to embed a cross-institutional advisor that supports the electrification components, but also other components that are happening in the country.
Second, we want the centre to be an innovation and strategy hub. Today, there’s really no place where you can go to find the state of the industry for productive use of energy across the globe, and we want to make the centre of excellence the place where you can go and get information about what technologies are available, where deployment is happening and how much is being deployed.

The third pillar is to coordinate and mobilise capital. We anticipate the centre coordinating internally within the ecosystem but also mobilising additional financing to help productivity. The last piece is how to scale businesses, enterprises and partnerships around this centre because we anticipate that as we grow this space, new industries will emerge and those industries will need to be supported.
Q: Why is productive use of energy becoming important under Mission 300?
A: Mission 300 gave us a bigger platform to demonstrate that energy is truly an enabler for economic development. It’s not sufficient to just provide a connection, but it is required that that connection truly translates to economic development for the communities that benefit.
We shouldn’t bring electricity and then start thinking about what people can do with it. We need to think about both at the same time and ensure electricity arrives together with the things that will make a difference in people’s lives. Historically, we’ve brought electricity and imagined a miracle would happen, but we know that hasn’t been the case.
The question is how to ensure universal access in the cheapest way while still transforming communities. Some mini-grids have been deployed in places where demand is extremely low, making them too expensive to sustain. But when mini-grids are paired with productive uses, the economics start to change. If businesses currently running on fossil fuel generators move to solar or renewable energy, operating costs fall and the business case for mini-grids becomes much stronger.
Q: How could this work in practice for agriculture and rural communities?
A: I’ll give you a practical example in our pilot country Zambia. Zambia has two programmes, they have the ASCENT programme for energy access and they also have the Zambia agribusiness and trade platform (ZATP). Some of the components of the ZATP programme – which is an agri-business program to help farmers to be productive – have a productive use component but don’t have an energy supply component. So we’re offering things like mills, processing facilities, irrigation and others. In some parts of Zambia, these productive use equipment has been supplied but has not been powered, so communities are not benefiting from that.
So the whole point is if we coordinate where the agribusiness programme is deployed together with where the energy access programme is deployed and layer those two programmes together in one place, then you could solve the energy access problem and solve productive use together and therefore have really meaningful outcomes for communities.
Q: How will the centre help both households and small businesses use electricity productively?
A: The question on whether we should electrify households or businesses is neither here nor there. We need to electrify all. The argument is really once we electrify businesses, the owners of those businesses will be able to pay what they need for their households as well as increase production for their businesses.
Electricity consumption is usually an indicator of economic development and by pushing productive use into households, especially where households are also smallholder farmers, the question becomes: how can electricity access translate to additional economic development for them? If you are connected onto a mini-grid, then you can actually use that connection to run irrigation, put in a dryer, or a cold storage system, whatever you require to improve your income but the fact that you have energy means that you can access productive use. Now, we need to ask ourselves how do these farmers or these households then get access to these appliances, because that’s another barrier.
Q&A: Will subsidy cuts for Chinese clean-tech exports hurt Africa’s solar boom?
The cost of these appliances is usually extremely high, and when you have programmes such as the ZATP running in Zambia, that’s already a public funding approach to making these appliances available and potentially reachable for farmers, either at household level, at farm level or at community level.
Q: How does this complement the already existing Mission 300 national energy compacts designed by countries?
A: Each of the national energy compacts have a productive use component, a pillar that talks about distributed renewable energy, productive use, and clean cooking. This is actually complementing the work of the countries, and this centre is like an available support, back office for countries to tap into as they implement their national energy compacts, if they have specific requirements and support for that pillar three.
So the advisers that will be embedded into countries, their role is to coordinate within country programs that are running where energy could make a difference. The advisers will be sourced from the country and so they will make sure that the donor money is coordinated to benefit the country fully. Their role will include going to ministries of agriculture or any related ministries and understanding where they are prioritising programmes that require electrification. In many cases, programmes and money have already been allocated, but this component is about how do we deploy it in a way that it actually truly brings a difference, so those advisers will do that.
Q: How will the centre address financing and private sector investment challenges?
A: What we’re really looking at is different financing mechanisms. In the past, we have provided subsidies and results-based financing to suppliers, distributors and manufacturers to help create markets for productive-use appliances. I see this as one mechanism the centre could use, but the bigger opportunity is aligning public funding across different programmes so that more of it can support productive uses, either through direct funding or subsidies.
Nigerians bet on solar as global oil shock hits wallets and power supplies
When it comes to private sector investment, the reality is that Africa’s energy sector still faces serious constraints. Most private investment has gone into power generation, particularly through independent power producers, and even then that has only been possible in places where the off-takers, usually utilities, are bankable.
To unlock more private capital, countries need the right policies, reforms and regulations, but even more importantly, utilities must become financially viable. If the off-taker is not bankable, then the project is not bankable.
Another major question is how to attract private investment into transmission infrastructure. There are different models being explored, but the reality is that public funding alone is not sufficient to achieve Mission 300, so finding new ways to mobilise private capital will be critical.

AI boom means US is now ‘investing more’ in fossil-fuel power than China
The “data-centre boom” is driving a surge in gas investment in the US, pushing its fossil-power spending ahead of China, according to the International Energy Agency (IEA).
A rapid expansion of data centres across the nation is at the heart of the US tech sector’s plans to continue “dominat[ing]” the global artificial intelligence (AI) industry.
High demand for electricity to power these data centres has led to companies rushing to build new gas-fired power plants across the country.
This trend, combined with “soaring” gas-turbine prices, drove a threefold increase in US gas‑power investment in 2025 – and the IEA expects this to continue throughout 2026.
As the chart below shows, Chinese investment in coal- and gas-fired power is expected to drop this year, amid domestic policy changes and the Iran war sending gas prices spiralling.
Together, these trends mean the IEA expects US investment in fossil-fuelled power plants to overtake China’s in 2026.

The IEA’s latest world energy investment report shows that spending on renewables and electricity grids continues to dominate at the global scale.
In the US, Trump administration policies such as the phase-out of tax credits for renewables has led to the IEA revising its forecast for new wind and solar power downwards.
At the same time, US electricity demand is expected to rise by an average of 2% per year from 2026 to 2030, with data centres contributing half of the overall increase.
This is leading to what the IEA calls an “AI-driven push” to build new gas-power plants in the US, the world’s largest data-centre market and largest gas producer.
Globally, orders for new gas-power plants increased to 130 gigawatts (GW) in 2025 – a 25-year high – and US demand was a “major factor” in this, according to the IEA.
Much of the demand is coming from tech companies in the US seeking to bypass grid connection queues by building “captive” gas-power plants.
As the chart below shows, since the start of 2025 these US captive data centres alone have signed off on more investment in new gas turbines than any country in the world – aside from the US itself.

Overall, investment in grid upgrades, power equipment and electricity generation to support the buildout of data-centre infrastructure around the world hit $105bn in 2025, according to the IEA.
This is more than the total invested in the energy sector across the whole of Africa – a continent where more than 600 million people do not have access to electricity.
The IEA notes that strong demand for gas-power plants for data centres in the US – and, to a lesser extent, the Middle East – is “limiting the availability of turbines for near-term deployment elsewhere in the world”.
The agency also points out that as the tech sector becomes a “major energy investor”, accounting for around 40% of all corporate power-purchase agreements, it is also “underpinning momentum” for emerging clean technologies, such as small modular nuclear reactors and advanced geothermal.

EM-DAT: Trump aid cuts could close database storing ‘world’s memory of disasters’
The world’s most comprehensive disaster database – relied on by thousands of climate scientists and policymakers – is at risk of closing as a result of cuts to US foreign aid by the Trump administration.
The “emergency events” database (EM-DAT) has for 30 years provided free-to-use information on the size and impact of extreme weather events and other disasters around the world.
Its data underpins a vast range of scientific research, government policymaking, humanitarian response efforts and environmental investigations.
However, Trump’s dismantling of the federal Agency for International Development (USAid) – which provided 90% of the funding for EM-DAT – has left the future of the database in jeopardy, scientists tell Carbon Brief.
An open letter coordinated by climate scientists and signed by more than 4,000 academics and students is calling on governments, multilateral development banks and philanthropy to step in to stop the database from closing.
‘World’s memory of disasters’
For the past three decades, a small team of researchers at the Centre for Research on the Epidemiology of Disasters (CRED) at the University of Louvain in Belgium have maintained EM-DAT.
It is the world’s most comprehensive database of extreme weather events, such as heatwaves, floods and tropical storms, along with other disasters. It offers information such as the timing and length of an event, how many people were killed or displaced and the economic cost.
Since 1988, this continuous record has been free to use and independently verified by the researchers at CRED.
When considered in its entirety, the database provides more than just a list of disasters – it acts as a “memory” of how extreme weather events and their impacts on people are changing, says Prof Niko Speybroeck, an epidemiologist and director of EM-DAT. He tells Carbon Brief:
“EM-DAT can be considered the world’s memory of disasters. It contains more than 27,000 natural and technological disasters. It’s not just a database. It makes it possible to know who was affected, when, where and with what consequences.”
The database is frequently used by climate scientists. It is often cited in research papers and underpinned analysis in the most recent Intergovernmental Panel on Climate Change (IPCC) report on the impacts of climate change.
It is also used by government officials and environmental organisations.
The database is particularly important for global-south nations, which are less likely to have comprehensive national or regional records of disasters than those in the global north.
For example, the Indonesian government used EM-DAT to develop a national strategy against disasters, says Speybroeck.
The database has also been used to document the “disproportionate climate burden” borne by small-island nations, he adds, which “prompted the UN to release more funding” for these states.
EM-DAT is of critical importance to national and multinational initiatives tracking extreme weather in Africa, says Prof Dewald van Niekerk, head of the African Centre for Disaster Studies at North-West University in South Africa. Van Niekerk was one of the climate scientists who authored the open letter calling for EM-DAT to be protected from closure. He tells Carbon Brief:
“We use it on various levels, from sub-national straight up to continental level.”
Since 2018, van Niekerk has utilised EM-DAT to prepare reports on extreme weather events in Africa for the African Union. These efforts are to meet goals agreed under the Sendai Framework for Disaster Risk Reduction, a voluntary international agreement to prevent disasters from upending development.
Without EM-DAT, it would not be possible to conduct such analyses, he says:
“Not all [African] governments can compile these databases. Where they do, they are extremely fragmented. You can’t compare apples with apples.”
(Carbon Brief has also used EM-DAT data to investigate the impact of extreme weather on Africa, finding that such events killed at least 15,000 people on the continent in 2023.)
Uncertain future
Despite having a global impact, EM-DAT’s small team of researchers require just €300,000 ($350,000) a year to maintain operations.
For decades, EM-DAT obtained 90% of this funding from USAid, the US’s federal agency for foreign aid, says Speybroeck:
“[USAid] allowed us to work in an independent and neutral way, so we were not influenced by any politics. That was one of the strengths of the database. They only asked for us to leave it open access, meaning that anyone can use it.”
USAid was dismantled by Donald Trump after he became US president for the second time in January 2025. By July, the agency officially closed its doors.
Speybroeck received a letter in February 2025 informing him that his team were to lose their funding.
“I decided for a long time to keep silent,” he tells Carbon Brief. However, by the end of 2025, he chose to start speaking out about the impact of USAid cuts on EM-DAT.
Learning of the threats to the database, four leading climate scientists published an open letter in March calling for other governments, multilateral development banks and philanthropy to step in to stop the database from closing. It has attracted more than 4,000 signatures.
One of the letter authors, Prof Gabriele Messori, director of the Swedish Centre for Impacts of Climate Extremes at Uppsala University in Sweden, tells Carbon Brief:
“It’s very worrying that a long-term dataset that has become a reference for many different sectors, when looking at the impacts of a wide range of natural and technological events on society and the economy, could be suddenly interrupted.”
(The cuts to EM-DAT’s funding come as the Trump administration has laid off thousands of scientists and frozen research grants worth billions of dollars in the US. For more on how these actions are impacting climate science, see Carbon Brief’s explainer on how Trump is threatening polar research.)
Since going public about EM-DAT’s funding crisis, Speybroeck says he has had some “positive signals” from potential new funders, but “there is nothing on paper yet”.
Another letter author, Prof Dewald van Niekerk, says he hopes to see EM-DAT move towards a model of using multiple funding sources, to create a “more robust structure” where “no one can just pull the plug” on its work.
