Abstract
Electricity demand has increased with population growth, industrialization and civilization. Most householders
are barely conscious of the conservative measures for available limited supply, while the environmental impact has
rarely been taken into cognizance by consumers. The study examines end-users attitude to energy consumption in
Nigeria based on four scenarios. Gaseous emissions data obtained from prepaid and post-paid metering systems usage
in low-income and high-income housing types were analyzed. Results obtained indicate strong relationship between
energy use and emissions with significantly different emission generation. About 38% and 23% reduction in global
warming and acidification potential is achieved by a switch to prepaid meters for both income earners. Post-paid
low-income earners utilized the highest energy (59.8kW/hr) while the prepaid high-income earners had the minimum
(31.1kW/hr). Energy use and greenhouse gas emissions from both earners followed similar trend. Prepaid metering
system usage improves energy consumption, thereby offsetting global warming and acidification impacts
