Ann: Clean energy zero carbon SOP, page-4

Renewables require subsidies to compete. Eritrea will probably have no interest in providing subsidies.
Geothermal is reliable but not cheap. The zero sum energy depends on solar panel being made in China using Australian coal which generates cheap industrial power. Solar PV panels, for example, are largely made in China using coal power at US$0.04 per kWh. Installed, the price of the power they produce is equivalent to that of diesel at about US$0.20/kWh. If you tried to use power from solar PV panels to make more panels, the power from those panels would cost north of US$1.00 per kWh. The same story holds for wind power. Solar panels and wind turbines are not renewable; they are merely artefacts of cheap, coal-sourced power.
What will be the cost of installed ?diesel power at Danakali? That can compared with the estimates of renewable costs.
