Just talk, no work
This is with reference to "It's nice but not sunny" (January 1-15, 2015). It's surprising that today neither a gram of polycrystalline silicon nor a single silicon wafer is being produced in the country. These are the basic materials for making solar cells and photovoltaic (PV) modules, which produce electricity from sunlight. Given that the cost of PV modules is about US $0.5 per Watt, the country would need a foreign exchange of US $0.5 trillion for importing 100 GW of PV modules.
