All of us must have seen the public service message by PEPCO to conserve electricity and save Pakistan from the debilitating energy crisis. But PEPCO apparently did not think about streetlights, which are kept on even during afternoon. As a matter of fact it is aggravating to witness that streetlights switched on during the day. They no doubt further aggravate the problem. What is this? Is this not deliberate wastage of electricity? The people who administer these streetlights must be kept under check and asked to shut down the lights regularly. Electricity must be conserved honestly and efficiently.
