How Solar and Wind Power Can Help Africa Get More Electricity

When we were kids, we learned that Tanzania gets its electricity from places like the Ruvu and Mtera dams, which use water to generate power.

But now, the story is expanding. Today, we’re also tapping into the sun and wind for energy. Africa has a lot of potential for renewable energy, including solar and wind power, which could help light up homes and support economies.

More than 600 million people in Africa still don’t have electricity. To address this, we need to include renewable energy sources in our plans. According to the Africa Renewable Energy Database, some countries, like Nigeria and Zimbabwe, aim to move away from fossil fuels by 2050.

If these plans succeed, 76% of Africa’s electricity could come from renewables by 2040. This would primarily include hydropower, solar power, and wind power.

Despite these goals, there are significant challenges and realities that could hinder this transition:

  1. Current Energy Demand: Many African countries still rely heavily on fossil fuels to meet their existing energy needs. Rapidly shifting away from these sources could create energy shortages, especially in regions where renewable energy infrastructure is not yet fully developed.

 

  1. Economic Dependence: Fossil fuels provide substantial revenue and employment in many African countries. Phasing them out too quickly could lead to economic disruption, including job losses and reduced income, potentially slowing down the transition to renewable energy.

 

  1. Infrastructure Challenges: Developing the necessary infrastructure for renewable energy, such as solar panels, wind turbines, and modern power grids, requires significant investment and time. Many countries may struggle with the cost and technology needed for this transition.

 

  1. Energy Storage and Reliability: Renewable energy sources like solar and wind are intermittent, meaning they don’t always produce power when it’s needed. Effective energy storage and grid management solutions are needed to ensure a reliable power supply, which remains a complex and costly challenge.

 

  1. Political and Social Factors: Political instability and resistance from industries dependent on fossil fuels can impede progress. Ensuring a stable policy environment and managing vested interests is crucial but often difficult.

 

  1. Cost and Access: The upfront costs of renewable energy technologies can be high. Some countries may find it challenging to finance these investments and might need to continue using fossil fuels temporarily to meet immediate energy demands.

A comprehensive study that reviewed 1,074 hydropower, 1,128 solar, and 276 wind power plants across Africa provides a clear overview of these resources.

It shows where these plants are located, their status, and their capacities. Countries like Eswatini, Angola, Tanzania, and the Democratic Republic of Congo rely heavily on hydropower, while others, like Egypt, South Africa, and Morocco, still depend on fossil fuels.

If all planned hydropower projects are completed, Africa’s hydropower capacity could more than double. However, with climate change and rising costs, relying solely on hydropower may not be sustainable. Combining hydropower with solar and wind energy could be a better approach.

To improve electricity access across Africa, the following steps are crucial:

  1. Share Power Across Borders: Countries should collaborate to share renewable energy resources.
  2. Consider the People: Involve local communities in energy development decisions.
  3. Learn from Past Mistakes: Share experiences to avoid issues like those from the Aswan High Dam.
  4. Share High-Quality Data: Access to accurate data is essential for planning and decision-making.

By following these steps, Africa can make significant progress in renewable energy and serve as a model for other regions.
