New Delhi, Apr 1 (IANS): Greenpeace India Monday protested poor electricity supply in the city, demonstrating outside the Vidhan Sabha here on the penultimate day of the budget session.

A poster with the caricature of Delhi Chief Minister Sheila Dikshit took a dig at her for assuring, without having any concrete plan, uninterrupted electricity supply this summer.

"The protest was staged to remind the Delhi government and legislators about the impending electricity crisis. Delhi will suffer in the coming summer due to the state's over-dependence on coal," said a statement from Greenpeace, an NGO.

"The chief minister, who is contesting elections later this year to seek an unprecedented fourth term, should understand that the real solution to the power crisis in Delhi does not lie in being over-dependent on technologies based on coal, which is becoming expensive, but increasing investment in renewable energy like solar and Biomass to create sustainable future and long-lasting energy infrastructure for the state," said Abhishek Pratap, energy campaigner, Greenpeace India, in the statement.

At the onset of summer, many areas of Delhi have already started witnessing unscheduled power outages. The massive grid failure and blackout in July 2012 has evidently showed that energy from fossil fuels and coal is not reliable, said the statement.
