Potential and cost of CO2 emissions mitigation by using solar photovoltaic pumps in India

An attempt has been made to develop a simple framework for quantification of the CO2 emissions estimation of potential of solar photovoltaic (SPV) pumps and associated cost of mitigation in India. Using the estimated annual useful energy provided by an SPV pump and the efficiency of utilization of the diesel/electricity in the conventional pump, the annual saving of diesel/electricity has been estimated. The gross annual amount of CO2 emissions mitigation as well as net amount of annual CO2 emissions mitigation potential is estimated by taking into account the CO2 emissions embodied in the SPV pump. The annualized costs and benefits of the SPV pump have been estimated and the same have been used to estimate the unit cost of CO2 emissions mitigation. Break-even analysis for an SPV pump to be a no regret option for CO2 emissions mitigation has also been undertaken.
