Why People Invest in Renewable Energy: Lessons for Expanding Energy Access in Africa

Renewable energy investment is often discussed in terms of technology, finance and infrastructure. While these factors are important, one question deserves greater attention: what motivates ordinary people to invest in renewable energy?

Understanding investor behaviour is essential for governments, policymakers and businesses seeking to mobilise finance for Africa's energy transition. If renewable energy projects are to scale successfully, they must align not only with financial expectations but also with the values, preferences and confidence of potential investors.

Looking Beyond Financial Returns

Investment decisions are rarely driven by financial returns alone.

Research examining household investment preferences shows that people consider a combination of financial and non-financial factors when deciding whether to support renewable energy projects. Trust, transparency, environmental benefits, project credibility and confidence in developers all influence investment behaviour alongside expected returns.

This highlights an important lesson for renewable energy developers: attracting investment requires more than offering competitive returns. Investors also need confidence that projects are well managed, transparent and capable of delivering meaningful social and environmental outcomes.

Why This Matters for Africa

Across Africa, achieving universal access to modern energy will require significant private investment alongside public funding.

Innovative financing approaches — including community investment models, crowdfunding and blended finance — can help mobilise new sources of capital for renewable energy projects. However, these mechanisms are only effective when they build trust and respond to investor preferences.

“Understanding what motivates investors can improve project design, increase participation and accelerate the deployment of renewable energy technologies.”

Building Confidence Through Evidence

For policymakers and project developers, evidence-based decision-making is essential. Research into investor behaviour provides valuable insights that can inform:

• Renewable energy financing strategies
• Community energy programmes
• Policy design
• Investor engagement
• Project communication
• Risk management

By understanding the human factors behind investment decisions, organisations can design projects that are more attractive to investors and more likely to achieve long-term success.

The Road Ahead

Africa's energy transition will depend not only on technology and finance but also on people.

Creating the right investment environment requires trust, strong institutions, transparent governance and projects that deliver measurable economic, social and environmental benefits.

At Bridge Energy Solutions, we believe that combining research with practical implementation helps governments, businesses and development partners develop energy solutions that attract investment and create lasting impact.
