 So from a viewer in your home country, Zimbabwe, in solving Africa's chronic energy problem, finding alternative renewable energy sources is important. What role do you think energy conservation can play to solve this problem? Thank you, Zimbabwe. Energy conservation is actually one of the biggest things that we should be looking at before we even try and look for new solutions. People say we need to develop all these technologies and do all sorts of things but you don't know what you've got till it's gone. So the first thing is to save as much energy as possible, save your environment, take care of your fossil fuels and stuff like that because you're actually destroying your world and before you know it you actually have to produce twice as much energy just to cover up for that. So conservation of energy is a big thing and also we're not expanding, unfortunately our energy resources are not expanding at the same rate as at which we need energy and at which the population is increasing. So we need to balance that out somehow. So yeah, I think conserving energy is a big thing.
