There is this report which says that the heat wave in Delhi is such that the (constantly used?) A/C's are exploding. Much more interesting is the news that the night temperature in Delhi is high because the concrete jungle, it seems, absorbs heat during the day, and releases it at night.
Such reports sure wake us up to the real need for sustainable development . In my opinion, without realising it, they draw attention to an easy solution to the environmental issues that come in the way of the sustainable development.
Any guesses about what I am referring to? Well, yes, I am referring to the solar energy available in abundance in a country like ours. Except for the monsoon, we get lots of sunshine. Even in the winters, noon onwards, it is quite sunny.
Why are we wasting all that energy? Well, solar energy is the most natural mode of energy which is environment friendly. Electric vehicles may not guzzle petrol/diesel. Yet the making of a battery involves mining while producing it. Later, dismantling the used up batteries would also pollute the environment.
The solar energy is free of all such dangers. The only obstacle would be making it light-weight both design wise as mounting it would thus be easy and by making all the apertures cost effective. An Australian university has researched through all such problems. I am sure the authorities are taking cognizance of such experiments. Or else, I could share the link if I could get to know how to. Solutions exist. Let us apply them.
Pratima@ It is always better to be the solution rather than be the problem. Like the simple system of rain water harvesting that can enrich the depleted water table!
