How cross-border electricity trade can supercharge Africa’s energy transition

Africa’s energy transition is at a pivotal moment. While the continent boasts abundant renewable energy resources, its electricity generation and distribution remain fragmented. Cross-border electricity trade has emerged as a potential game-changer, fostering energy security, reducing costs, and accelerating the adoption of renewables. However, is Africa fully leveraging this opportunity?

In a forthcoming paper in the Energy & Environment journal, I join forces with my colleagues Mercy Adaji and Bereket Kebede to argue that the answer to this question is no. Our study examines the impact of cross-border electricity trade in renewable electricity generation across 21 African countries over a 24-year period (1996–2020). Our findings indicate that a 1% increase in electricity trade significantly raises the share of renewables in total electricity output by approximately 0.05%. This underscores the crucial role of regional integration in advancing Africa’s clean energy goals, aligning with previous studies (e.g., Boz et al., 2021; Song et al., 2022, linked below) that highlight how electricity market integration promotes renewable energy investments by stabilising supply and mitigating intermittency risks.

Despite these advantages, cross-border electricity trade remains significantly underutilised due to regulatory barriers, inadequate infrastructure, and governance challenges.

Net electricity-importing countries tend to benefit more from trade, while net-exporting nations, particularly those reliant on fossil fuels, exhibit weaker positive impacts. Without targeted policies (such as carbon pricing and green subsidies) trade disparities may persist, slowing the transition to clean energy.

Moreover, our results highlight the pivotal role of governance in fostering a robust electricity market. This is neither surprising nor new – quality of governance matters over the long term in all aspects of economic activity. Agostini et al. (2019), for instance, show that well-structured regulations and strategic investments in interconnections enhance the effectiveness of cross-border electricity trade. Transparent regulatory frameworks, expanded grid interconnections, and harmonised energy policies can significantly boost the impact of regional electricity trade.

By strengthening collaboration, African nations can mitigate energy poverty, enhance supply reliability, and accelerate the shift toward a greener future.

To capitalise fully on cross-border electricity trade, African policymakers must prioritise regional energy integration, invest in infrastructure and implement incentives to spur renewable energy expansion. With the right policies and co-operative strategies, Africa can harness its vast renewable potential and achieve a more sustainable, energy-secure future.

‘Tariff is the most beautiful word.’ Not for economists!

In an interview with Joe Rogan for his podcast, The Joe Rogan Experience, just before the US election, Donald Trump stated that, “To me, the most beautiful word – and I’ve said this for the last couple of weeks – in the dictionary today and any is the word ‘tariff’. It’s more beautiful than love; it’s more beautiful than anything. It’s the most beautiful word. This country can become rich with the use, the proper use of tariffs.”

President-elect Trump has stated that he will impose tariffs on imports of 10% or 20%, with 60% and 100% tariffs on imports from China and Mexico, respectively. This protection for US industries, combined with lighter regulation, will, he claims, provide a stimulus to the economy and help create jobs. The revenues will also help to reduce America’s budget deficit.

But it is not that straightforward.

Problems with tariffs for the USA

Imposing tariffs is likely to reduce international trade. But international trade brings net benefits, which are distributed between the participants according to the terms of trade. This is the law of comparative advantage.

In the simple two-country case, the law states that, provided the opportunity costs of producing various goods differ between the two countries, both of them can gain from mutual trade if they specialise in producing (and exporting) those goods that have relatively low opportunity costs compared with the other country. The total production and consumption of the two countries will be higher.

So if the USA has a comparative advantage in various manufactured products and a trading partner has a comparative advantage in tropical food products, such as coffee or bananas, both can gain by specialisation and trade.

If tariffs are imposed and trade is thereby reduced between the USA and its trading partners, there will be a net loss, as production will switch from lower-cost production to higher-cost production. The higher costs of less efficient production in the USA will lead to higher prices for those goods than if they were imported.

At the same time, goods that are still imported will be more expensive as the price will include the tariff. Some of this may be borne by the importer, meaning that only part of the tariff is passed on to the consumer. The incidence of the tariff between consumer and importer will depend on price elasticities of demand and supply. Nevertheless, imports will still be more expensive, allowing the domestically-produced substitutes to rise in price too, albeit probably by not so much. According to work by Kimberly Clausing and Mary E Lovely for the Peterson Institute (see link in Articles below), Trump’s proposals to raise tariffs would cost the typical American household over $2600 a year.

The net effect will be a rise in inflation – at least temporarily. Yet one of Donald Trump’s pledges is to reduce inflation. Higher inflation will, in turn, encourage the Fed to raise interest rates, which will dampen investment and economic growth.

Donald Trump tends to behave transactionally rather than ideologically. He is probably hoping that a rapid introduction of tariffs will then give the USA a strong bargaining position with foreign countries to trade more fairly. He is also hoping that protecting US industries by the use of tariffs, especially when coupled with deregulation, will encourage greater investment and thereby faster growth.

Much will depend on how other countries respond. If they respond by raising tariffs on US exports, any gain to industries from protection from imports will be offset by a loss to exporters.

A trade war, with higher tariffs, will lead to a net loss in global GDP. It is a negative sum game. In such a ‘game’, it is possible for one ‘player’ (country) to gain, but the loss to the other players (countries) will be greater than that gain.

Donald Trump is hoping that by ‘winning’ such a game, the USA could still come out better off. But the gain from higher investment, output and employment in the protected industries would have to outweigh the losses to exporting industries and from higher import prices.

The first Trump administration (2017–21), as part of its ‘America First’ programme, imposed large-scale tariffs on Chinese imports and on steel and aluminium from across the world. There was wide-scale retaliation by other countries with tariffs imposed on a range of US exports. There was a net loss to world income, including US GDP.

Problems with US tariffs for the rest of the world

The imposition of tariffs by the USA will have considerable effects on other countries. The higher the tariffs and the more that countries rely on exports to the USA, the bigger will the effect be. China and Mexico are likely to be the biggest losers as they face the highest tariffs and the USA is a major customer. In 2023, US imports from China were worth $427bn, while US exports to China were worth just $148bn – only 34.6% of the value of imports. The percentage is estimated to be even lower for 2024 at around 32%. In 2023, China’s exports to the USA accounted for 12.6% of its total exports; Mexico’s exports to the USA accounted for 82.7% of its total exports.

It is possible that higher tariffs could be extended beyond China to other Asian countries, such as Vietnam, South Korea, Taiwan, India and Indonesia. These countries typically run trade surpluses with the USA. Also, many of the products from these countries include Chinese components.

As far as the UK is concerned, the proposed tariffs would cause significant falls in trade. According to research by Nicolò Tamberi at the University of Sussex (see link below in Articles):

The UK’s exports to the world could fall by £22 billion (–2.6%) and imports by £1.4 (–0.16%), with significant variations across sectors. Some sectors, like fishing and petroleum, are particularly hard-hit due to their high sensitivity to tariff changes, while others, such as textiles, benefit from trade diversion as the US shifts demand away from China.

Other badly affected sectors would include mining, pharmaceuticals, finance and insurance, and business services. The overall effect, according to the research, would be to reduce UK output by just under 1%.

Countries are likely to respond to US tariffs by imposing their own tariffs on US imports. World Trade Organization rules permit the use of retaliatory tariffs equivalent to those imposed by the USA. The more aggressive the resulting trade war, the bigger would be the fall in world trade and GDP.

The EU is planning to negotiate with Trump to avoid a trade war, but officials are preparing the details of retaliatory measures should the future Trump administration impose the threatened tariffs. The EU response is likely to be strong.

Crude oil – a volatile market

The market for crude oil is usually a volatile one. Indeed, in the last few months, the market has seen prices rise and fall due to various supply and demand influences. Crude oil is coined the ‘King of Commodities’ due to the impact it has on consumers, producers and both the micro and macro economy. The price of crude oil affects everything from the cost of producing plastics, transportation, and food at the supermarket.

This makes the market for crude oil an economic powerhouse which is closely watched by businesses, traders, and governments. To gain a full understanding of the movements in this market, it is important to identify how demand and supply affect the price of crude oil.

What influences the demand and supply of crude oil?

The law of demand and supply states that if demand increases, prices will rise, and if supply increases, prices will fall. This is exactly what happens in the market for crude oil. The consumer side of the market consists of various companies and hundreds of millions of people. The producer side of the market is made up of oil-producing countries. Collectively, both consumers and producers influence the market price.

However, the demand and supply of crude oil, and therefore the price, is also affected by global economic conditions and geopolitical tensions. What happens in the world impacts the price of oil, especially since a large proportion of the world’s biggest oil producers are in politically unstable areas.

Over the past five years, global events have had a major impact on the price of oil. The economic conditions created by the impact of the COVID pandemic saw prices plummet from around $55 per barrel just before the pandemic in February 2020 to around $15 per barrel in April 2020. By mid-2021 they had recovered to around $75 per barrel. Then, in the aftermath of Russia’s invasion of Ukraine in February 2022, the price surged to reach $133 in June 2022. More recently, geopolitical tensions in the Middle East and concerns about China’s economic outlook have intensified concerns about the future direction of the market. (Click here for a PowerPoint of the chart.)

Geopolitical tensions

In the first week of October 2024, the price of crude oil rose by almost 10% to around $78 per barrel as the conflict in the Middle East intensified. It unfortunately comes at a time when many countries are starting to recover from the rise in oil prices caused by the pandemic and the war in Ukraine. Any increase in prices will affect the price that consumers pay to fill up their vehicles with fuel, just when prices of diesel and petrol had reached their lowest level for three years.

The Governor of the Bank of England, Andrew Bailey, has said that the Bank is monitoring developments in the Middle East ‘extremely closely’, as the conflict has the potential to have serious impacts in the UK. The Bank of England will therefore be watching for any movement in oil prices that could fuel inflation.

The main concerns stem from further escalation in the conflict between Israel and the Iran-backed armed group, Hezbollah, in Lebanon. If Israel decides to attack Iran’s oil sector, this is likely to cause a sharp rise in the price of oil. Iran is the world’s seventh largest oil exporter and exports over half of its production to China. If the oilfields of a medium-sized supplier, like Iran, were attacked, this could threaten general inflation in the UK, which could in turn influence any decision by the Bank of England to lower interest rates next month.

Supply deficits

This week (2nd week of October 2024) saw the price of crude oil surge above $81 per barrel to hit its highest level since August. This rise means that prices increased by 12% in a week. However, this surge in price also means that prices rose by almost 21% between the start September and the start of October alone. Yet it was only in early September when crude oil hit a year-to-date low, highlighting the volatility in the market.

As the Middle-East war enters a new and more energy-related phase, the loss of Iranian oil would leave the market in a supply deficit. The law of supply implies that such a deficit would lead to an increase in prices. This also comes at a time when the US Strategic Petroleum Reserve has also been depleted, causing further concerns about global oil supply.

However, the biggest and most significant impact would be a disruption to flows through the Strait of Hormuz. This is a relatively narrow channel at the east end of the Persian Gulf through which a huge amount of oil tanker traffic passes – about a third of total seaborne-traded oil. It is therefore known as the world’s most important oil transit chokepoint. The risk that escalation could block the Strait of Hormuz could technically see a halt in about a fifth of the world’s oil supply. This would include exports from big Gulf producers, including Saudi Arabia, UAE, Kuwait and Iraq. In a worst-case scenario of a full closure of the Strait, a barrel of oil could very quickly rise to well above $100.

Disruption to shipments would also lead to higher gas prices and therefore lead to a rise in household gas and electricity bills. As with oil, gas prices filter down supply chains, affecting the cost of virtually all goods, resulting in a further rise in the cost of living. With energy bills in the UK having already risen by 10% for this winter, an escalation to the conflict could see prices rise further still.

China’s economic outlook


Despite the concern for the future supply of oil, there is also a need to consider how the demand for oil could impact price changes in the market. The price of oil declined on 14 October 2024 in light of concerns over China’s struggling economy. As China is the world’s largest importer of crude oil, there are emerging fears about the potential limits on fuel demand. This fall in price reversed increases made the previous week as investors become concerned about worsening deflationary pressures in China.

Any reduced demand from China could indicate an oversupply of crude oil and therefore potential price declines. Official data from China reveal a sharp year-on-year drop in the producer price index of 2.8% – the fastest decline in six months. These disappointing results have stirred uncertainty about the Chinese government’s economic stimulus plans. Prices could fall further if there are continuing doubts about the government’s ability to implement effective fiscal measures to promote consumer spending and, in turn, economic growth.

As a result of the 2% price fall in oil prices on 14 October, OPEC (the Organization of the Petroleum Exporting Countries) has lowered its 2024 and 2025 global oil demand growth. This negative news outweighed market concerns over the possibility that an Israeli response to Iran’s missile attack could disrupt oil production.

What is the future for oil prices?

It is expected that the market for oil will remain a volatile one. Indeed, the current uncertainties around the globe only highlight this. It is never a simple task to predict what will happen in a market that is influenced by so many global factors, and the current global landscape only adds to the complexity.

There’s a wide spectrum of predictions about what could come next in the market for crude oil. Given the changes in the first two weeks of October alone, supply and demand factors from separate parts of the globe have made the future of oil prices particularly uncertain. Callum Macpherson, head of commodities at Investec, stated in early October that ‘there is really no way of telling where we will be this time next week’ (see the first BBC News article linked below).

Despite the predominately negative outlook, this is all based on potential scenarios. Caroline Bain, chief commodities economist at Capital Economics suggests that if the ‘worst-case scenario’ of further escalation in the Middle East conflict does not materialise, oil prices are likely to ‘ease back quite quickly’. Even if Iran’s supplies were disrupted, China could turn to Russia for its oil. Bain says that there is ‘more than enough capacity’ globally to cover the gap if Iranian production is lost. However, this does then raise the question of where the loyalty of Saudi Arabia, the world’s second largest oil producer, lies and whether it will increase or restrict further production.

What is certain is that the market for crude oil will continue to be a market that is closely observed. It doesn’t take much change in global activity for prices to move. Therefore, in the current political and macroeconomic environment, the coming weeks and months will be critical in determining oil prices and, in turn, their economic effects.
