This is a great topic.
There is so much Nigeria can be and can do.
You need honest government right down to local level before it can happen
I could write all night. You see I live in a very small country that is presently not realising its huge potential because it is subsumed into the United Kingdom but all my life I have imagined what we could do in an independent Scotland (we used to be independent) and we are getting there now. It is because we can dream what we can do that keeps us going on and reaching for a better future. Nigeria needs its dreamers who can imagine the great things that Nigeria can do and be prepared to work politically for it.
But honest government is the first requirement.
When I was an inspector in the Educational Resource Centre (KERC) near the zoo the physics depatment were making solar panels that could boil water out of glass panels and car radiators and all kind of other experiments were going on. They were producing small windmills powered by heat convection out of concrete pits even on calm days. The biggest solar panel in the world was near Zinder when I was in Nigeria. Nigeria could easily supply all its lighting needs from storing solar power.Your two major rivers could have several dams on them for hydro power. Bio diesel can be produced from corn and groundnuts.
The nuclear power solution is ultimately non-viable as the world is running out of uranium.
Irrigation and the storage of seasonal rains would revolutionise the north. If this was done seriously it would probably change the weather patters and lengthen the rainy season. It is over half a century since Bagauda and Tiga dams were planned. Has anything else along these lines been done with the vast sums of money available to Nigeria over this time or has it all been stolen. The oil money will eventually come to an end and what will Nigeria do then if it hasn't been used to restructure the Nigerian economy, revitilise agriculture and build a modern infrastructure with modern provision of services.
