Techno-Economic Analysis for the Role of Single End Energy User in Mitigating GHG Emission

Abstract

Background End energy user relies on fossil fuel-based national grid to meet their energy demand; hence, indirectly contributing towards greenhouse gases (GHG) emission and causing climate change. This study aims to investigate the minute role of a single, end energy user in GHG mitigation by shifting to the green renewable energy source, photovoltaics (PV) through its techno-economic analysis. Method For the study impact, NASA Meteorological Data is used to select an ideal single energy user equipped with 10 kW PV system based on annual- average daily solar radiations and temperature through MATLAB/Simulink, among eleven populous cities of Pakistan. Helioscope software is used to select tilt and azimuthal angle to expose PV surface for most of the solar radiations. Afterwards, RETScreen software is used for cost, financial and GHG analysis. Results and Conclusion The proposed system at single end energy user mitigates 6.9 tonnes of CO2 per annum while producing 16,832 kWh per annum and recovering its 7337$ capital cost in less than five years in the project’s 25-year life span. A single energy user invisible to national grid can play a pivotal role in GHG mitigations while earning from its investment and achieving energy independency from the main grid at the same time.
