Energy, economic, and environmental analysis of a flat-plate solar collector operated with SiO2 nanofluid

To overcome the environmental impact and declining source of fossil fuels, renewable energy sources need to meet the increasing demand of energy. Solar thermal energy is clean and infinite, suitable to be a good replacement for fossil fuel. However, the current solar technology is still expensive an...
