By Tarik Sfendla

The energy markets are undergoing a massive transformation as governments around the world transition away from fossil fuels towards the integration of renewable energy. This trend is clearly visible in the mining industry as demonstrated by recent power projects in South America and in Australia.

According to Bloomberg New Energy Finance, in 2018, mines purchased 1 GW of renewable energy generation assets; this amount tripled to reach approximately 3.5 GW in 2019, 90% of which consists of hybrid solutions.

Electricity demand for the mining industry is expected to increase significantly in the coming years as increased mine depth, harder rock and greater water desalination needs lead to higher energy intensity for the industry.

Whilst electrification of operations and vehicles is reducing certain emissions and generating cost savings, stakeholder targets to reduce emissions as part of the EESG (Environmental, Economic, Social & Governance) plans, is increasing the renewable share of the energy mix, which of course requires high flexibility in the generation to balance intermittent renewables.

In Africa, the mining sector faces inherent challenges, access to the power grid and grid reliability being the most significant. With most electricity supply coming from conventional power plants (coal, oil or gas), operators are challenged on the one hand with highly volatile operating expenses due to rising fuel costs, and by inefficient, unreliable power supply leading to costly production disruption and revenue losses on the other. Weak infrastructure and water availability compound the challenges for mines, particularly in remote, off-grid locations.

The combination of these trends and particularities of the African markets are setting the scene for the integration of renewables for the mining sector. A recent study by McKinsey showed that moving to renewable electricity sources is becoming increasingly feasible, even in off-grid environments, as the cost of electricity storage is set to decline by 50% from 2017 to 2030. This is especially good news for Africa where the cost of solar energy generation could be among the lowest in the world.

It also represents a huge opportunity for operators in Africa, where Wärtsilä has developed a range of competitive strategies to deliver efficient and reliable power supply solutions to support the mining sector on its path towards a renewable energy future.

In Tanzania, the Geita gold mine was experiencing reliability issues and power shortages as its ageing power plant was reaching the end of its useful life. It needed a reliable power generation solution to support its growing operations.

Wärtsilä delivered a 40 MW flexible power plant and agreed to a 10-year operation and maintenance (O&M) package, integrating technology with lifecycle services to provide “always-on” power. The plant secures uninterrupted off-grid power supply, eliminating revenue losses from power shortages, while the O&M agreement is tailored to the mine’s day-to-day performance requirements.

Maintenance schedules are optimised to minimize costs and production downtime and enhance fuel efficiency. As a result, fuel savings of around 4%, representing $2 million USD, were achieved in the first year of operation. The flexibility of the installation will also facilitate the transition to renewables over the project lifetime.

In Burkina Faso, Wärtsilä has delivered a 15 MWp solar photovoltaic (PV) power plant to the independent power producer (IPP) Essakane Solar SAS, which supplies the Ekkasine gold mine.  The solar PV plant was constructed next to a 55 MW power plant running on heavy fuel oil. The engine power plant provides backup, while the solar farm produces energy during the day. The capability to control and optimise the usage of the solar PV power and engines enables the gold mine to reduce its fuel consumption by an estimated 6 million litres per year and its annual CO2 emissions by 18,500 tons.

Energy Storage technologies are the true game-changer

The integration of energy storage technologies will be the real game-changer, enabling the industry to take full advantage of cheap and plentiful solar power. They have the unique ability to provide a buffer between supply and demand by delivering or storing energy whenever it is most needed. They will become the key building block of the stable infrastructure needed to improve grid reliability and security.

Hybrid solutions, combining flexible thermal generation with storage and solar power operations are now a realistic and cost-effective solution, as the levelled cost of electricity (LCOE) is lower than ever, and costs of storage are set to decline.

In Mali, at the Fekola mine, located in a remote area with no connection to any larger grid, Wärtsilä is providing an off-grid hybrid solution to provide and maintain microgrid stability. The project combines a 30 MW solar PV plant, a 17.3 MW / 15.4 MW energy storage facility and GEMS, Wärtsilä’s advanced energy management system, with the mine’s existing 64 MW power generator to improve power reliability, reduce heavy fuel consumption, save costs and reduce CO2 emissions.

GEMS is a ground-breaking tool, using smart algorithms to dispatch energy storage and multiple generation assets (thermal and renewable) with the right reserve level to maintain high grid reliability for the mine. Gensets are switched off as solar output increases and are restarted based on forecasted data including load demand and weather. The sophistication of GEMS enables energy production optimization to ensure the lowest LCOE.

In addition to ensuring microgrid stability, the project is expected to generate long-term annual savings of 13.1 million litres of heavy fuel oil and reduce the mine’s carbon footprint by approximately 39,000 tons per year. This hybrid storage project is the first of its kind in Mali and in the mining sector, demonstrating the growing case for clean energy and its sustainable and economic potential for mines in Africa and elsewhere.

Increasing energy reliability and lowering operating costs are essential for the mining sector. The optimal solution to solve the power challenges must allow for fast starting with high off-grid availability, high fuel efficiency, fast load following and part-load efficiency to allow high penetration of renewables. The answer lies in a combination of advanced flexible energy generation strategies and the smart use of renewables to guarantee the delivery of efficient and reliable power in remote off-grid locations. Advanced energy management systems are the key technological element required to support the huge inflows of power from intermittent sources.

With an extensive portfolio of energy storage and flexible solutions for energy-intensive operations, in Africa and the rest of the world, Wärtsilä is the partner of choice to support the mining sector achieve its sustainability and cost-saving goals.

Stocks vs Forex

By Onah Ishioma Adaeze

As a beginner, choosing between stocks and forex for your investment goals in 2026 can feel overwhelming. Before investing your hard-earned money, it is important to understand how both markets work.

While both markets present investors with opportunities to grow their wealth, they also differ in terms of volatility, liquidity, market hours, and leverage. Stocks involve owning portions of a company, while forex has to do with trading a base currency against a quote currency.

In this article, we will be going through the basics of stocks and forex, pointing out their differences, and helping you decide which asset better suits your investment journey in 2026.

What is Stock Trading?

When it comes to stock trading, you are buying shares of a company, which makes you a shareholder of that company. As a shareholder, you may be entitled to receive dividends whenever the company decides to pay dividends.

As for those companies that do not pay dividends, there are other benefits a shareholder may enjoy, like being called upon to attend shareholder meetings and having voting rights on certain company matters.

On a global scale, over $100 trillion worth of shares are traded annually. Also, the rising popularity of AI companies and technological innovations continues to drive investor participation and market growth.

If you’re an investor looking to buy and hold capital assets, then stock trading is definitely for you, as it allows for short-term, medium-term and long-term investment goals.

When you buy shares of a company and the company performs well, your shares increase in value. Another benefit of stock trading is access to index funds and ETFs.

These funds consist of companies that are grouped under an index. They are carefully selected and monitored under the fund, sparing the investor the stress of actively tracking the fund.

They can be a way of building a long-term, diversified portfolio, and some of these funds may pay dividends.

What is Forex Trading?

Forex trading has to do with buying one currency and selling another. With a pair like USD/JPY, USD is the base currency being bought against JPY, which is the quote currency.

In order to execute a trade in the forex market, you have to analyse and make predictions based on price movement, as well as pay attention to what’s going on in the global news scene.

The forex market runs twenty-four hours every weekday, with over $9 trillion traded in the market every day. Being the largest financial market in the world, there is very high liquidity.

Forex trading involves buying one currency against another, making predictions based on price movements on the forex charts. Price moves based on the activities of large institutions like hedge funds, big banks, the government, etc.

The forex market runs 24 hours a day, every weekday, with global forex turnover reaching $9 trillion per day in the BIS 2025 survey. Being the largest financial market in the world, there is very high volatility and price fluctuations.

At the same time, there is high liquidity in the market, which means that currency pairs can easily be bought and sold without hassle. Highly liquid instruments that are traded regularly include: EUR/USD, USD/JPY, GBP/USD, and gold (XAU/USD).

As a retail trader, knowing when to enter and exit the market is important. As easy as it is to make profits from price fluctuations, it is also very easy to lose money if the market moves against you. This is why it is important to set stop losses and take profits. This helps manage your trading capital.

Major Differences Between Stocks and Forex

While investing in stocks and forex can yield great capital gains, there are lots of ways in which they differ.

As a beginner, stock trading provides opportunities for long-term investments, ensuring slow but consistent returns for wealth building. But if you are looking for an active, short-term style of investment, then forex trading is for you, as it allows you to enter and exit the market within a shorter time frame.

Which is Better in 2026?

Choosing an asset to invest in all boils down to personal preference. At the same time, if you are not averse to risk, nor opposed to asset diversification, then it’s okay to invest in both.

For beginner investors in 2026, stock trading is easier to understand and get into, especially because of mutual funds, index funds and ETFs. With those funds, you don’t have to be an expert to start investing. You can just buy a fund that suits your needs and hold it over a long period of time.

If you are an investor who enjoys technical analysis, highly volatile and liquid markets, as well as trading under short time frames, then forex trading is the right pick for you.

Conclusion 

You do not need to put all your eggs in one basket. There are investors who invest in both stocks and forex simultaneously. When starting out, you can start investing in stocks while learning forex. Take calculated risks and do not invest above your means. Diversify your investments and remember, when starting out, you should prioritise acquiring knowledge over profits.

Building 234 Solutions: A Response to Everyday Workforce Challenges

Published

Owoloye Emmanuel 234 Solutions

By Owoloye Emmanuel

Every business starts with a problem. For us, that problem was hiding in plain sight.

Across organisations, we kept seeing HR professionals, payroll teams, and business leaders spend significant time navigating processes that should be simpler. Employee records sat across multiple systems, payroll processes required manual intervention, and routine workforce tasks often became more complicated than they needed to be.

As businesses grow, workforce operations naturally become more complex. Yet many organisations still rely on disconnected tools and workflows that create unnecessary friction for both employers and employees.

The consequence is more than operational inefficiency. HR teams spend valuable time managing systems instead of supporting people. Business leaders struggle to access timely workforce insights, while employees experience delays in processes that should be seamless.

These weren’t isolated challenges. They were recurring realities across workplaces, regardless of industry or size.

That observation led us to a simple question: what if workforce management could be easier?

What if HR, payroll, and workforce operations could work together within a single, connected experience?

That question became the foundation for 234 Solutions.

We are building 234 Solutions with a clear belief that workplace technology should reduce complexity, not add to it. Our goal is to help organisations spend less time navigating processes and more time focusing on productivity, growth, and people.

As we prepare for launch, our focus remains simple: building practical solutions for real workplace challenges and helping organisations create better experiences for the people who power them every day.

The Role of TV in Preserving African Stories and Identity

Published

Preserving African Stories

Scroll through social media today, and you will notice something interesting: everyone is either reacting to a series, quoting a movie line, or debating a character as though they personally know them. Beneath the memes and binge-watch culture, however, lies something deeper. Television remains one of the most powerful tools shaping how Africans see themselves, remember their history, and tell their own stories. In a continent as diverse and expressive as Africa, that matters more than ever.

TV as a Cultural Archive, Not Just Entertainment

Long before streaming algorithms began shaping our viewing habits, television was already preserving African identity. From Nollywood dramas that capture the rhythm of everyday Lagos life to documentaries exploring Maasai traditions and Ghanaian folklore, TV has served as a living archive of the continent’s stories.

It preserves more than entertainment; it preserves language, culture, humour, values, and shared experiences. Unlike fleeting social media content, television allows stories to unfold with depth, exploring the realities of family, tradition, ambition, and modern African life without reducing them to stereotypes. That is the power of TV: preserving not just stories, but perspective.

Why Representation on TV Still Matters

There is a subtle but important truth: if people do not see themselves on screen, they may begin to believe their stories are not worth telling. This is why African TV content is more than entertainment; it is affirmation.

Seeing a character who speaks like you, struggles like you, or celebrates like your community does something powerful. It validates identity and challenges outdated narratives that have historically defined Africa through external lenses.

This is where MultiChoice Group, through platforms such as DStv and GOtv, plays an important role. They do not simply broadcast content; they help distribute cultural memory at scale.

GOtv, DStv, and the Everyday African Viewer

Think about a typical evening in many African homes: the TV is on in the background, someone is laughing at a comedy show, another person is watching a local series, and someone else is catching up on the news. That shared viewing experience remains very real.

Through platforms such as DStv and GOtv, African households are exposed to a blend of local storytelling and global content. More importantly, they have helped amplify African-produced content by bringing Nollywood films, African reality shows, talk shows, and documentaries into mainstream rotation.

It is not just about access. It is about visibility.

A young filmmaker in Lagos today is more likely to believe their story matters because they have seen similar stories broadcast widely. A child in Accra grows up hearing familiar accents and seeing environments that look like their own on screen, not as exceptions, but as the norm.

TV Is Also Shaping Modern African Identity

African identity is not static; it is evolving. Television reflects that evolution in real time.

Today, audiences see:

  • Young Africans balancing tradition and modern dating culture

  • Stories tackling mental health in African households

  • Fashion and music influences spreading through TV series

  • Political satire shaping public conversation

Conversations that were once confined to homes are now being explored on screen, giving audiences the language to discuss issues that were previously unspoken.

In many ways, television is doing what oral tradition has always done: passing stories, values, humour, warnings, and history from one generation to the next. The difference is that today’s griots are writers, directors, and broadcasters.

The Future: From Watching to Owning Our Narratives

The next stage of African storytelling is not just about being seen; it is about ownership.

As more African creators produce content and platforms continue to invest in regional storytelling, television becomes more than a mirror. It becomes a tool for shaping how Africa is represented to itself and to the world.

While streaming continues to grow, television, particularly accessible platforms such as GOtv, remains one of the most effective ways to reach everyday audiences across different income levels and regions. After all, storytelling only matters if people can access it.

African stories are not new. They have always existed in families, on streets, in markets, in history books, and through oral traditions. What television has done, and continues to do, is give those stories a stage wide enough for millions to experience them at once.

The next time you watch a local series or documentary on DStv or GOtv, remember that you are not just being entertained. You are participating in the preservation of African identity itself.
