Estimation of the Global Solar Energy Potential and Photovoltaic Cost with the use of Open Data

There is an increasing demand for renewable electricity sources, due to the global efforts to reduce CO2 emissions. Despite the promising effects, only a limited amount of electricity is currently produced globally from solar power. In order to help countries realize the importance of tapping into...
