Claim 0:
1. A system comprising:
a greenhouse;
spectrum selective nanofluid configured to flow around the greenhouse roof and absorb some or significant portion of solar spectrum having a wavelength equal to or greater than 750 nm to reduce a cooling load inside the greenhouse;
an evacuated tube collector (ETC) configured to convert a solar energy into a first heat;
a photovoltaic thermal (PV/T) system having a photovoltaic (PV) cell, wherein the nanofluid is further configured to absorb a second heat from the PV/T system, reducing a temperature of the PV cell, wherein the second heat absorbed from the PV/T system is used to pre-heat saline water;
a desalination mechanism configured to receive the pre-heated saline water and distill the pre-heated saline water; and
a cooling mechanism configured to cool the greenhouse using the first heat generated from the ETC.
