Overlying this is a need for cleaner air. The Paris Accord on climate change has brought the world together in a pledge for lower emissions, so where fossil fuel is used, we must use the latest clean technology.
In my view, ‘climate deniers’ are those who pretend we can impose our will on others in the name of global warming, as though all 193 member states of the UN will magically come to heel. There is no room in 2020 for playing the ‘colonial overlord’ and it may even push some away from the goal of a cleaner planet. And what happens if a government decide to use oil, coal or gas? Do we go to war, impose sanctions, expel them from the General Assembly?
So, how about giving them the technology to burn it cleanly?
I am a scientist and have spent my working life researching how to get rid of toxic byproducts when using different types of fuel. At the clean-coal facility at the University of Witwatersrand in Johannesburg, we have done just that. We remove much of the dirt from the coal before it even enters the furnace, redesigning ovens to produce more heat and less fumes, and capturing what’s left, then harvesting elements for sale as byproducts.
I have overseen masters and doctoral degrees for academics from across Africa who have the same dream, and we liaise with like-minded schools in the US, Europe, Latin America, Asia and Australia.
The engineers and scientists we work with around the world are not tub-thumpers or activists. They are scholars doing peer-reviewed work on clean coal. Think of the smoky old cars we had in the 50s, and the early jet engines. Fast forward to unleaded fuel and energy-efficient planes: neither is anywhere near as clean as the new way of using coal.
Across Africa, firewood is still the most common source of energy for warmth and cooking, and it comes at a terrible cost to nature. By this I do not mean just the loss of trees, but habitats destroyed for everything from insects to elephants. West Africa has cut down an estimated 90 per cent of its forest. According to the Worldwide Fund for Nature, Kenya and Tanzania have done the same with their coastal forests. Logging also has a huge effect on weather patterns and the environment.
Why does this continue? A major contributor is the lack of electricity. If we want to save our forest then the only way in Africa is by connecting homes to mains electricity. That means for those countries that continue to use fossil fuel and especially coal, we must put money and research into a clean burn.
In northern Mozambique, the world’s biggest new gas field is being opened up with a jump in jobs and wealth. Do we tell them to stop? And would the government in Maputo listen? Mozambique has one of the world’s largest coal mines at Moatize, earning millions in foreign exchange. Should we bomb it? Angola and Nigeria earn almost all their income from oil. Will they shut the wells? Will Saudi or Venezuela?
