The Inconvenient Truth with Ing. Prof. Douglas Boateng: Solar for now, balance for the future – Africa’s energy choice cannot wait

…A six year solar push can ease today’s crisis, but only a disciplined mix of hydro, gas, thermal, wind, geothermal, bioenergy, ocean wave and nuclear will secure tomorrow’s industrial power

By Ing. Prof. Douglas Boateng

The search for one answer

In moments of pressure, nations often search for one answer.

1. One source.
2. One miracle.

1. One announcement.

Solar is praised. Hydro is defended. Gas is justified. Thermal is relied upon. Wind is admired. Geothermal is underutilised. Bioenergy is overlooked. Ocean wave energy is imagined. Nuclear is postponed. Coal is quietly debated. Yet no serious industrial economy is powered sustainably by one source alone. The inconvenient truth is this: energy security is not achieved by choosing favourites. It is achieved by building balance.

NyansaKasa (Words of Wisdom): “A nation does not secure its energy future by worshipping one source, but by wisely balancing many for generations yet unborn.”

Reflection: Energy security comes from disciplined integration, not dependence on a single solution.

Solar must lead the next six years

For the short term, solar deserves urgent priority. It is fast to deploy. It is modular. It can reduce pressure on the national grid within months. A serious six year solar push can move schools, hospitals, clinics, offices, farms and households partly off the grid during the day. This reduces demand, frees capacity for industry and stabilises supply. India, South Africa and Kenya have demonstrated how decentralised solar can reduce grid pressure while expanding access.

The inconvenient truth is this: solar is not the final answer, but it is the fastest way to regain control of the present.

NyansaKasa (Words of Wisdom): “When the load is heavy, the wise do not wait for a new road, they lighten the burden.”

Reflection: Solar provides immediate breathing space while long term systems are built.

Solar’s limits must still be respected

Solar depends on sunlight. It fluctuates. It requires storage or complementary supply. Factories do not wait for sunrise. Industrial systems require continuity. Solar must be prioritised, but not romanticised.

Hydro for balance

Hydropower remains vital, supported by institutions such as the Volta River Authority and the Bui Power Authority. But climate variability now makes water risk unavoidable. Hydro must be managed carefully and complemented by other sources.

NyansaKasa (Words of Wisdom): “The river that sustained yesterday must still be watched tomorrow.”

Reflection: Dependence without adaptation creates vulnerability.

Thermal, gas and coal: the stabilisers we must manage wisely

Thermal power remains the backbone of many African grids.

It includes gas fired plants, oil based generation and, in some countries, coal. It provides:

1. Reliable and dispatchable power
2. Immediate response to demand
3. Stability when renewables fluctuate

Gas is often the preferred transition fuel due to lower emissions compared to coal and oil. Coal, while increasingly discouraged globally due to environmental concerns, still plays a role in some economies where energy security pressures outweigh environmental considerations in the short term.

The inconvenient truth is this: thermal power, including gas and in some cases coal, remains essential for stability today, but must be carefully managed to avoid long term economic and environmental burdens.

NyansaKasa (Words of Wisdom): “The fire that keeps you warm can also consume your home if left unchecked.”

Reflection: Dependable systems must be balanced with responsibility and long term vision.

Wind: the natural complement

Wind energy complements solar. It diversifies renewable supply and, in some regions, produces power when solar output declines. Countries such as Morocco and South Africa have successfully integrated wind into their energy mix. Wind is not an alternative to solar. It is a partner to it.

Geothermal: the quiet baseload strength

Geothermal energy provides continuous, stable baseload power. Countries such as Kenya have demonstrated its value, with geothermal supplying a significant portion of national electricity. It is reliable, low carbon and not dependent on weather cycles.

The inconvenient truth is this: geothermal may be Africa’s most underutilised stable renewable resource.

NyansaKasa (Words of Wisdom): “The fire beneath the earth does not flicker like the wind or fade like the sun.”

Reflection: Geothermal offers stability where other renewables fluctuate.

Bioenergy: turning waste into power

Bioenergy, derived from agricultural waste, forestry residues and organic materials, offers a unique opportunity for Africa.

It can:

1. Convert waste into energy
2. Support rural economies
3. Reduce environmental pollution
4. Provide decentralised power solutions

Countries such as Brazil have demonstrated how bioenergy can support both energy production and agricultural value chains. For Africa, where agricultural activity is extensive, bioenergy represents both an energy and economic opportunity.

The inconvenient truth is this: Africa produces vast amounts of biomass waste, yet captures only a fraction of its energy potential.

NyansaKasa (Words of Wisdom): “What we throw away today may power our tomorrow.”

Reflection: Waste is often a resource waiting for discipline and innovation.

Ocean wave: the future frontier

Ocean wave energy remains emerging but promising. For coastal nations, it offers long term diversification.

1. It is predictable.
2. It is vast.
3. It is largely untapped.

Africa must begin research, pilot projects and policy development now.

NyansaKasa (Words of Wisdom): “The sea that feeds us today may power us tomorrow.”

Reflection: Future energy systems must include emerging opportunities.

Nuclear for generational power

Nuclear energy provides stable, continuous, low carbon baseload power. It requires strong governance, technical expertise and long term commitment. Countries serious about industrialisation recognise its importance. Nuclear is not for immediate relief. It is for generational industrial strength.

NyansaKasa (Words of Wisdom): “The foundation that lasts is laid long before the house is complete.”

Reflection: Long term energy security requires patience and foresight.

Practical energy mix matrix for african leaders

Beyond election cycles

Energy systems are not built within political timelines.

1. Solar can deliver quick wins.
2. Thermal stabilises the system.
3. Wind and hydro balance supply.
4. Geothermal anchors stability.
5. Bioenergy supports communities.
6. Ocean wave opens future potential.
7. Nuclear secures the long term.

The inconvenient truth is this: energy security requires thinking beyond election cycles and committing to generational strategies.

NyansaKasa (Words of Wisdom): “The future does not reward the hurried. It rewards the prepared.”

Reflection: Enduring systems are built through patience and discipline.

A final reflection: from relief to mastery

1. Solar can relieve the crisis.
2. Thermal can stabilise it.

1. Wind can complement it.
2. Geothermal can anchor it.
3. Bioenergy can empower communities.

• Ocean wave can expand possibilities.
• Nuclear can secure the future.

Together, they form a system.

The inconvenient truth is this: the energy choices made today will define Africa’s economic independence for generations.

The path forward is not ideological. It is strategic. Balanced. Integrated. Disciplined. And perhaps the most important truth of all: A nation that combines solar for relief, thermal for stability, hydro for balance, wind for diversity, geothermal for baseload, bioenergy for communities, ocean power for the future and nuclear for generational strength does not merely survive its energy crisis. It begins to master it.
