Clean Energy Could Be Malawi’s SME Survival Strategy If Access is Affordable

Renewable efficient energy can help Malawian SMEs withstand climate shocks, but adoption is uneven. Targeted support, gender inclusion, information access, and institutional backing are critical to ensure vulnerable firms benefit. For Malawi and other Global South economies, resilience is not built through technology alone; it requires integrated systems, policy support, and equitable access to finance and knowledge.

For Malawi's small and medium-sized enterprises, climate change is increasingly a threat to day-to-day survival. Erratic rainfall, rising temperatures, droughts, floods and energy disruptions can interrupt production, weaken supply chains, raise operating costs and reduce business continuity. For firms already operating with limited capital and thin cash buffers, even temporary shocks can become long-term setbacks.

A new study published in World examines whether renewable efficient energy systems can help Malawian SMEs become more resilient in this environment. The article, titled Modelling and Estimating the Climate Resilience for Renewable Efficient Energy Systems Among Small and Medium-Sized Enterprises in Malawi, was authored by Victor Lucky Limbe, Sydney Nkhoma, Mwayi Mambosasa, Joseph Mahuka and Steven Henry Dunga. It uses data from 699 SMEs drawn from the 2019 Malawi Integrated Household Survey and focuses on the country's main urban centres, including Lilongwe, Blantyre and Mzuzu.

Can renewable efficient energy systems, including solar, biogas and energy-efficient technologies, strengthen SME resilience against climate-related shocks? The answer is cautiously positive. The research finds that SMEs adopting renewable efficient energy systems are more resilient than they would have been without adoption. However, it also shows that the benefits are not automatic, and that adoption remains shaped by credit access, education, assets, information, social capital, gender and location.

SMEs are central to Malawi's economy. They support household incomes, create jobs and connect agriculture, agro-processing and trade. Malawi's development strategies have identified SME growth as a priority for economic transformation. Additionally, the global development agenda links clean energy, economic growth and climate action through SDG 7, SDG 8 and SDG 13. The study sits directly at the intersection of those priorities.

Renewables Build Resilience, But Gaps Remain

The study measures resilience as a multidimensional capacity: the ability of SMEs to absorb shocks, adapt during disruptions and transform after crises. A business does not become climate-resilient simply by installing a solar panel or switching to a more efficient appliance. It also needs savings, information, markets, credit, infrastructure, networks and institutional support.

Using the Sustainable Livelihoods Framework, the authors construct a Resilience Capacity Index with three dimensions. Absorptive capacity refers to the ability to withstand shocks and is measured through factors such as asset ownership, cash savings, income, livestock ownership, soil quality and informal safety nets. Adaptive capacity captures the ability to adjust during shocks and includes access to information, improved infrastructure, education, age, gender and bridging social capital. Transformative capacity reflects the ability to recover and improve after shocks through access to markets, extension services, credit, land and formal safety nets.

Transformative capacity plays the strongest role in long-term SME resilience. In practical terms, this means that firms need more than short-term coping tools. They need access to markets, credit, extension services and formal support systems that help them recover and become stronger after disruption. The finding shifts the policy conversation away from emergency response alone and toward long-term institutional support.

The study uses an Endogenous Switching Regression model to estimate the impact of renewable efficient energy adoption while accounting for selection bias. Firms that adopt clean energy may already differ from non-adopters. They may have more assets, better information, stronger networks or greater credit access. The model attempts to compare actual outcomes with counterfactual scenarios: what adopters would look like without adoption, and what non-adopters might look like if they adopted.

The results show that adoption improves resilience among firms already using renewable efficient energy systems. The Average Treatment Effect on the Treated is 0.117, meaning adopters gain measurable resilience benefits compared with their estimated non-adoption scenario. This suggests that clean energy can help SMEs maintain operations, reduce exposure to energy disruptions and improve their capacity to handle climate-related shocks.

However, the study also finds that adoption is not equally beneficial for all firms under current conditions. For current non-adopters, the estimated Average Treatment Effect on the Untreated is negative at -0.474. The authors interpret this as evidence of a potential liquidity shock: vulnerable SMEs may face upfront costs that outweigh short-term resilience benefits if they are pushed to adopt without adequate support. This is one of the study's most important insights. Clean energy can be a resilience tool, but only when firms can afford the transition.

Access Decides Who Benefits

The study identifies several factors that increase the likelihood of adopting renewable efficient energy systems. Credit access, education, access to capital sources, asset ownership, higher profit share, being an SME manager, urban location, age, access to information, extension services, bridging social capital and safety nets all positively influence adoption.

The findings show that adoption depends on both financial and non-financial conditions. Credit and assets help firms meet upfront costs. Education and information help owners understand the benefits and operation of clean energy systems. Extension services and bridging social capital connect businesses to advice, training and external support. Urban location may reflect better infrastructure, service availability and technology access.

The study also finds important barriers. Female-owned SMEs are less likely to adopt renewable efficient energy systems. The authors link this to resource constraints, weaker access to credit, collateral barriers and smaller business networks. This raises a major policy concern: without gender-responsive support, clean energy programmes could reinforce existing inequalities by benefiting better-capitalized, male-owned firms first.

Larger household size also reduces adoption likelihood, likely because household needs compete with business investment. Reliance on informal safety nets is negatively associated with adoption, which the study interprets partly through fragmented, low-value or redistributive support systems that may reduce incentives or capacity for private investment. Lack of bonding social capital also weakens adoption prospects by limiting exposure to trusted information.

The policy simulations deepen the argument. A broad loan-access scenario produces only a limited resilience gain, with a weakly significant improvement of 0.0119. This suggests that universal financial support may not be enough to drive meaningful resilience gains. But targeted support for vulnerable firms has stronger potential: the Vulnerability-Relevant Treatment Effect indicates that vulnerable SMEs that later adopt renewable efficient energy could raise resilience by 0.169.

Policy should not simply make clean energy available; it should make adoption viable for the firms most exposed to risk. It requires concessional loans, targeted grants, technical advice, information centres, gender-sensitive finance, and support systems that reduce the risk of taking on new technology.

Policy Must Target Risk

Many developing countries face a similar challenge: SMEs are expected to contribute to growth, jobs and innovation, but they operate in environments marked by climate shocks, unreliable infrastructure and limited finance. Renewable energy is often promoted as part of the solution, but the study shows that adoption pathways are unequal.

Governments should integrate clean energy policy with SME development and climate adaptation strategies. Malawi could benefit from urban information centres where business owners can learn about renewable efficient energy technologies, costs, financing options and long-term benefits. But information alone will not be enough. Firms need access to formal capital sources, extension services, market linkages and risk-reduction tools.

For development agencies and international organizations, the research supports targeted climate finance. Instead of relying only on broad subsidies or generic loans, programmes should identify vulnerable SMEs with weak cash buffers, limited collateral and low access to formal finance. These firms may need grants, concessional credit, guarantees, technical training and phased repayment models to avoid liquidity stress.

The study points to a market opportunity and a responsibility for financial institutions and clean-energy providers. Products for SMEs must be affordable, transparent and adapted to irregular income patterns. If financial products are too rigid or expensive, they may exclude precisely the firms that need resilience support most.

For civil society and business associations, the gender gap deserves attention. Female-owned SMEs may need targeted outreach, collateral alternatives, financial literacy support and stronger business networks. Without this, renewable energy adoption could widen rather than narrow business resilience gaps.

The study uses a large SME sample, applies a multidimensional resilience framework, estimates adoption drivers and uses an econometric model designed to address selection bias. It also distinguishes average policy effects from vulnerability-specific effects, which makes its recommendations more useful for policymakers.

The limitations are also important. The study uses 2019 secondary data, which may not capture more recent economic shocks, energy-market changes or post-pandemic business conditions. The sample is drawn from Malawi's main urban centres, so results may not fully apply to rural SMEs or smaller towns. The authors also acknowledge limitations around instrumental variables, including the possibility that access to technology-specific gifts or loans may reflect unobserved social capital or creditworthiness.

Future research should compare different renewable technologies separately, including solar, biogas and energy-efficient appliances. Longitudinal studies could show whether resilience gains persist over time. Rural samples would help clarify whether the same adoption drivers operate outside urban centres. Pilot programmes could also test bundled interventions combining finance, training, information, market access and gender-responsive support.
