There were well intentioned policy makers in some few industrialized countries who wanted to have some contribution of Renewable Energies on their electricity generation mix Two tehcnologies -which were conceptually modularprofited from their easy installation and from the virtuous circle “volume – cost reduction” They were widely deployed and reached affordable  cost figures per kWh. It looked so nice that people started dreaming with an emission free generation system

But these technologies couldn’t satisfy the demand at all time of day and more and more conventional power plants needed to be built. Then people woke up from their dreams and started to consider Solar Thermal Electricity plants as key for the future
