Beatrice Mwella

Job Title: Energy Data Intern

Company: SEforALL
Country: Tanzania

What exactly do you do in your current job?

In my current role, I work at the intersection of energy, data, and policy to help improve electricity access and reliability in Africa. I analyse national power system data, develop evidence-based insights, and support decision-makers with tools that guide investments in grids, renewable energy, and energy efficiency. Beyond the technical work, I contribute to research and storytelling that highlights real challenges behind electricity access such as outages, unreliable supply, and unmet demand, so that energy solutions better reflect people’s lived realities.

What inspired you to start working in sustainable energy?

Growing up, I experienced firsthand what unreliable electricity means—missed study time, disrupted businesses, and daily life constantly adapting to power cuts. Over time, I realised that energy is not just about electricity; it is about opportunity, dignity, and development. That understanding inspired me to work in sustainable energy, so solutions are not only technically sound, but also truly improve people’s lives.

Can you tell us about how you got started working in energy?

My journey began through formal training in electrical engineering, followed by a master’s degree in power systems engineering. Along the way, I combined academic research with hands-on projects focused on electricity access, grid reliability, and energy planning in Africa. I then transitioned into policy and data-driven work, where I now support energy planning, research, and decision-making at a regional and continental level.

What do you love about working in the sustainable energy sector?

I love that the work sits at the intersection of technology, policy, and people’s everyday realities. Every analysis or project has the potential to influence real outcomes—whether that’s powering schools, enabling businesses, or supporting climate-resilient development. It’s a sector where your work can be both intellectually challenging and deeply meaningful

What advice or encouragement would you give to girls and young women considering a career in sustainable energy?

You do not need to have everything figured out to start—curiosity and willingness to learn are enough. Don’t be discouraged by spaces where women are underrepresented; your perspective is needed. Seek mentors, ask questions boldly, and remember that sustainable energy is a broad field—there is space for engineers, analysts, communicators, policymakers, and entrepreneurs. Your background and lived experience can be your greatest strength.
