Trust a hard-nosed business newspaper like The Wall Street Journal to make the case that Renewable Energy is about saving money and not about some loony left-wing desire to save the world: Link Somehow, the morons who go around with a messianic zeal touting Renewable Energy never make the case that the use of RE is good economics. You save money over the long term because you use natural energy that you do not have to spend money to access - sunlight is free compared to buying electricity generated from coal or whatever other source, reduced pollution means less sick people and less spend on keeping your environment clean, less spending on medical treatment etc and much more. The list goes on and on.
In a country like India or Sri Lanka where most of the year brings abundant sunlight, this could mean immense savings in electricity costs, as hot water is something that everyone needs. The import of coal from other countries would slow considerably because electricity would not need to be used for heating as much as it is. Power shortages and outages would also be reduced as the load on the generation and transmission system would be minimized. Yes, without beginning with the intention of becoming another Mahatm Gandhi or Nelson Mandela, it would be possible to become self-reliant, conscientious and to save the world as well as one's own finances in a world that is increasingly getting more expensive to live in. Now, if only the loudest voices for renewable energy could see things this way . . .
