It’s summer again, the hottest season of the entire year has come. In a country like India, the summers can get quite hot, therefore to escape the heat, we use a variety of measures for cooling our homes. For that, we purchase air conditioners and coolers, but the irony is that the money we spent on these items to cool down our homes makes the world a much hotter place to live. The reason for this is the chemical by-products that are produced from the appliances which increase the temperature. So, what can be an effective way to cool down this summer.
