Solar energy cut grid power consumption by about 46% in government schools, says study

Why in news

Tamil Nadu ministers released a report showing that rooftop solar installations in 97 government schools reduced grid electricity consumption by 46% per school.

Background

The study, conducted with the Indian Institute for Human Settlements (IIHS), found an average annual saving of 3,572 units of electricity and ₹26,000 in costs per school. The state's 'Green School' program aims to expand from 25 pilot schools to 300 schools to offset up to 91% of power consumption.
