Water savings and enhanced energy yield through land-neutral

solar power plant

Yellow 2 Gen Energy Pvt. Ltd. Gurgaon URL: www.yellow.org.in

WHY? Our primary purpose is to optimally utilize under-utilized natural resources while addressing the paradox of ‘scarcity amidst plenty’ in context of renewable energy penetration.

Why go land-neutral?

Land has multiple uses – opportunity cost ¡  Land acquisition
