Those of us who worry about mobile phones draining out of charge while travelling may have a solution – solar mobile rechargers that use sunlight instead of electricity. Among the innovations on display at ‘Renergy’, a two day international conference and expo on renewable energy inaugurated on Monday, the most attractive was the solar mobile charger.

Coping with Power Cuts – Trichy Shows the Way

English: Trichy Junction

With no power to run mixers and grinders, the forgotten Ammi kal and Aattu kal (grinding stones) are making a comeback.  Surprisingly, this has drawn a lot of appreciation from families as the pounded ingredients add a distinct flavor, says home-maker Priyadarshini.

Cauvery Matriculation HSS has tackled the power  cuts by distributing 70 solar lamps to Class X and XII students. “Students will return them after the Board exams,” said Saraswathi, Principal. Likewise, Bishop Heber College and Monfort HSS have set up solar lights on campus, and a philanthropist has donated 100 solar lamps to a government school at Tiruvellari.

 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.
