Wind pumps for irrigating greenhouse crops: Comparison in different socio-economical frameworks

A methodology is applied for economic evaluation of water pumping technologies. Different socioeconomic frameworks are considered for Spain, Cuba and Pakistan. The levelised cost of energy is used to determine the best technology. Wind speed, distance to grid, water storage size and elevation are considered. The water elevation has greater influence on wind pumps than on solar PV pumping.

Wind pumps for irrigating greenhouse crops: comparison in different socio-economical frameworks

Wind power can play an interesting role in irrigation projects in different areas. A methodology can determine the feasibility of the technology and the levels of daily irrigation demand satisfied by windmills at different levels of risk, using tomato (Lycopersicon esculentum Mill) as greenhouse crop. The present work compared the feasibility of the technology and the critical factors involved in three different countries: Cuba, Spain and Pakistan. The study considered as factors the wind speed level, the energy cost, the tomato prices, the reliability and distance to the electrical grid, and the crop development dates, determining the economic feasibility for each combination of factors in each country.
