"I think these statements smack of political expediency. They are trying to woo the voters by giving them these freebies and I think that it should be realised that these don't work in practice and irrational," Pachauri, Director General of The Energy and Research Institute (TERI), told PTI here.
"I think you have to run the electric utility business with proper regulation ... And run it in a responsible way. If there are sections of the society that deserve subsidy, please do that in a very transparent and in an effective way. But you do not give a blanket subsidy to everyone," Pachauri said.
Asked specifically about AAP promising an immediate 50 per cent cut in electricity prices, he said, "they may be doing this with the best of intentions but I am sorry they ought to think twice before making such statements. This would be my advice to any party and not just AAP or anybody else."
The 74-year-old was also optimistic about Indo-US collaboration in the fields of climate change and clean energy, saying India was a huge market for clean energy technologies and it could innovate and develop new technologies at much lower cost than the US.
