India is expected to have its first offshore windmill in Dhanushkodi in the next five years, according to Dr S Gomathi Nayagam, executive director of Centre for Wind Energy Technology, Ministry of New and Renewable Energy.
Speaking after inaugurating the two-day conference on Renewable Energy Sector Policy Challenges organised by Chennai-based Centre for Development Finance (CDF), a non-profit action research think-tank of Indian Institute for Financial Management and Research, in association with Friedrich Naumann Stiftung fur die Freiheit, Nayagam said it took 10 years for Germany to build offshore windmills, but India, after learning from the German experience, can build it in half the time.

Solar panels could be installed on terraces, tiled and even thatched roofs. The panels are charged particularly between 12 noon and 3 pm. Surendaran, who runs an electronic service centre adds, “I have installed a 45 watt solar panel to generate energy for my office.” A household would require an average of 100 watts per day for one fan and tubelight to function, he says. For this, a 100 watt solar panel is enough. The panels would require space of 8×2 feet.
Schools have begun to instruct students on the need to save power.
“Children have acclimatized themselves to live without power all the time. They now make sure that they open the windows to get air,” says Usha Raghavan, Principal, Amrita Vidyalayam, Tiruchy.
