Energy infrastructure fascinates me. So much of society is built around and is dependent on our energy supply. Over the years, the way we access energy has repeatedly been revolutionised. Now, we are painfully aware that a complete revolution is again necessary. The energy sector of South Africa, my home country, is not only unsustainably dependent on coal but urgently requires expansion to meet rising demand. This gives us a fantastic opportunity to develop our energy sector in a sustainable direction. During my MPhil in Engineering for Sustainable Development at Cambridge I will study the options available to developing countries and how we can implement the necessary changes. I will focus on the decentralisation of energy supply and solar electric power production. The practical aspects of sustainable development that this course teaches will build on the technical knowledge that I have gained through my undergraduate degree in chemical engineering and my professional experience in a small Namibian energy company. It is an exciting and dynamic time that we are living in. I am honoured to be joining the Gates Cambridge community: an inter-disciplinary cohort that are working to make that change positive.
