Turkey can largely wean itself off coal through rational and long-term measures. Why a comprehensive study has not been carried out is another question. But the scarcity of studies like this is quite common. For example, a smart cistern can save up to a quarter or third of the water you’d otherwise use to flush. Yet we’ve made no studies on the cost of installing a smart cistern and how much water it would save, not even a rough calculation of cost vs. benefit. The same is true for sensor taps in high usage areas, where it’s possible to save up to half as much water. Clearly, we need to consider consumption as well. Look around you at night, the whole city is ablaze with lights! Do we really need such dazzling illumination?
