Building a sustainable world today for a better tomorrow
Energy has long been a key driver of economic growth, sparking industrial revolutions and shaping modern economies. The first revolution, fuelled by steam engines and coal, paved the way for mechanised manufacturing and the rise of trains. Today, energy production is a significant contributor to global warming, accounting for about two-thirds of human-induced greenhouse gas emissions. This has led to a shift towards cleaner, more sustainable energy, with three key Sustainable Development Goals (SDGs)—Climate Action, Sustainable Consumption, and Affordable and Clean Energy—emphasising the importance of energy transition.In Namibia, considerable progress has been made in renewable energy, particularly solar and wind. The country’s renewable potential has been integrated into the National Integrated Resource Plan (NIRP), and regulatory frameworks, like the Modified Single Buyer (MSB) model, are promoting clean energy adoption. To date, 31 contestable customers, representing about 7% of national demand, are participating in the MSB model. Additionally, renewable energy technologies have matured, and the technical challenge of powering energy-intensive sectors like mining with clean energy has been addressed.
The mining industry plays a significant role in both global energy consumption and economic development. Energy costs make up 30-40% of mining companies' operating expenses, and the sector is at the forefront of adopting clean energy solutions to meet sustainability goals. However, while mining requires more metals and minerals for green energy generation, it also faces challenges. Mining activities are energy-intensive and high in carbon emissions, yet the sector can contribute positively by integrating renewable energy into its operations.
In Namibia, the mining sector’s contribution to the economy is substantial, with mining representing 14.4% of GDP and providing over 18,000 jobs. The country’s favourable regulatory framework supports clean energy in the industry, with the MSB model offering opportunities for mining companies to power operations through independent power producers (IPPs). However, challenges like fluctuating commodity prices and the technical limitations of renewable energy plants must be addressed to accelerate the uptake of clean energy.
Mining companies must lead the way in clean energy adoption. Leadership commitment is crucial, alongside a culture of energy conservation, addressing inefficiencies, and investing in renewable energy solutions like rooftop solar PV systems. Transitioning to electric or battery-electric fleets can also reduce emissions and simplify the energy transition. By embracing clean energy, the mining industry can drive sustainable economic growth and environmental stewardship, ensuring a cleaner, greener tomorrow.
