Renewable energy and climate change are closely connected issues. Part of the solution to the climate change problem can be funded through the thirst for renewable energy. Aquatic weeds, which clog many of your waterways, are the dessication machines that are drying your continent. They are biomass with altogether too much renewability. They can be made into ethanol, methane, biomass briquettes, and charcoal. They can replace much fossil fuel use, with all of the associated GHG. Clearing Africa's waters of these weeds, and dredging the silt that they have left will help restore the water cycle to health. There are many old rivers and lakes that have been completely dry for years. They must be dug out, back to their old beds. In time, the rains that come will get them back in contact with the underground water, restoring both. Cleanse your current wetlands, restore your old ones, and the climate will take care of itself again. You can finance it on the biofuel to be harvested.
