Power cut in the evening or night hours does not engulf the streets of JJ Nagar, a residential area with 120 houses about 10 km from Coimbatore city, in darkness. Nearly 90 per cent of the population here are daily wage earners and do not have uninterrupted power supply systems or generators. But, JJ Nagar has harnessed renewable energy.

A couple of months ago, 10 street lights in the panchayat were connected to a 500 watt solar system.
