As a trailblazer in the energy sector, what do you believe are the most critical factors for achieving sustainable and inclusive energy solutions in our cities?
Bridging gender gaps and integrating diverse perspectives are crucial for an inclusive energy transition. Women often face higher energy poverty due to lower incomes and more single-parent households. For instance, in South Africa, female-headed households make up about 40% of the population and often struggle with solar adoption. At Wetility, we address this by innovating our credit screening process. Our advanced financing risk approach allows greater inclusion than typical asset-agnostic institutions, helping to improve access to clean energy.
What advice do you have for young women aspiring to make a difference in the energy sector and overcome gender-related barriers in their careers?
The renewable energy sector is a crucial industry for the future that I encourage all young people to enter. My advice for young women entering this exciting space specifically, is to keep going and own your place. Energy impacts all our lives, yet whilst women make up 40% of the global renewable energy workforce, less than half hold senior roles. If someone can do it, then why not you. So be bold as an energy producer, policymaker, or leader. Have fun, be brave and shape a sustainable future for everyone.
What is one quote or mantra you live by and why?
One mantra that I try to live by is “decide and live”. We can often get stuck in paralysis of analysis, be deterred by setbacks or unable to have faith that overcoming the hurdles we see is possible. It is true as well that achieving Wetility’s vision of sustainable energy independence for everyone is indeed difficult. However, nothing ever changed without someone starting. So – wake up with determination, surround yourself with wonderful people, both professionally and personally, and go for it.
How has the way you have grown up influenced the woman you are today?
I grew up slightly unorthodoxly and was constantly moving cities and countries. This experience taught me the importance of deep personal connections and exposed me to many beautiful adventures, people, and experiences that the world has to offer. However, I also witnessed significant disparities, injustices and discrimination first hand, many of them gender-based. These experiences instilled in me a strong sense of justice, perseverance, and restlessness to ensure that women are heard, respected and never sidelined. This understanding drives much of what I do today.

As a trailblazer in the energy sector, what do you believe are the most critical factors for achieving sustainable and inclusive energy solutions in our cities?
Building or improving enabling infrastructure to facilitate energy access to all cities; Addressing all physical infostructure-related issues on-grid and off-grid to ensure that sufficient energy is distributed to everyone.
Including local communities in the decision-making process is important to understand better the critical needs and challenges communities face in transitioning to sustainable energy solutions.
Set-up and operational costs of renewable energy solutions can be higher than what low-income consumers can afford.
Invest in local energy, and foster business opportunities between local municipalities and independent energy producers to eradicate energy poverty.
What advice do you have for young women aspiring to make a difference in the energy sector and overcome gender-related barriers in their careers?
Always focus on what motivated you to be in the space. When the pressure builds up, the imposter syndrome pops up, and the tough times arise. Always look within and remember your “WHY” that will always keep you going in life. Remember some programmes support women to succeed, always seek those and make sure you are part of a community that aligns with your goals and career vision.
What does breaking barriers and bias mean to you?
Doing what you love, are passionate about, believe in, and vowed to provide without conforming to negativity and compromising your values and principles. Always rising above challenges, and delivering your best work even when the odds are against you, without ever compromising your integrity.
How has the way you have grown up influenced the woman you are today?
I grew up in a household where putting food on the table was the end goal. This motivated me to be resilient and fostered independence and a go-getter mindset. With an understanding that only I have the power to change my situation nobody else not even my parents are obligated to save me in life.
