Strategic alternatives to end power crisis

“Decentralised solar power generations especially when DC power is generated directly,  is not much expensive than the grid power,”saysDr Ashok Jhunjhunwala,Founder of TeNet Group, IIT Madras
 Power cuts continue to plague Indian states. The government has been looking for new methods and technology for uninterrupted power supply that could end rolling blackouts. Dr Ashok Jhunjhunwala has pioneered a slew of technologies in different sectors and now he desires to end power cuts in India. In an exclusive interview with Shahzad Bagwan, he discusses the concept called brownout and methods to prevent power cuts.
What is your take on the current scenario of power shortage in India?Power shortage has been rising. More can be done to generate required power, but power shortage could still be there. Therefore we need to try to enhance demand and at the same time do a few other things too address the demand-supply gap.
We need to evolve the demand-supply scenario considering details like generation, reduction of demand by increasing energy efficiency. So increasing energy efficiency will also play a major role.
What alternatives do you plan to use to reduce the shortage and how sustainable are these alternatives?There are three things we are trying to do. Firstly, to significantly increase energy efficiency we are using direct current (DC) powered light, fans, chargers for electronic products so that power wastage can be significantly be reduced. In volumes none of these solutions are more expensive. In comparison to CFL lightning LED is expensive but LED has a higher life span. The other DC solutions are not expensive than the AC solutions so are sustainable.
Secondly, we are talking about decentralised solar power generations. Decentralised solar power generations especially when DC power is generated directly,  is not much expensive than the grid power. It is equivalent to the similar charges for grid power which is around Rs. 5 per unit so again it is sustainable. If it is installed by individuals and if the direct output is DC, then it is extremely beneficial.
