Sir: Every government promises to produce electricity by building more dams and using the Thar coal reserves. But why do they shy away from installing prepaid meters and laying underground electricity lines to prevent theft? Even if the government increases supply of electricity in a few years, people would still steal electricity. Load shedding will not be eliminated until power theft is controlled, which is only possible when people pay for what they consume. And prepaid meters can make this happen. This is the only way to get away from circular debt, the mother of all evils prompting the electricity crisis. Ghazanfar Ali KhanKarachi
