India's solar energy installed capacity has swelled from practically nothing to more than 2 GW in the three years since the creation of the Jawaharlal Nehru National Solar Mission Phase 1 (JNNSM). Impressively, costs have come down rapidly (to roughly $0.12/kWh for solar PV, and $0.21/kWh for CSP) to be competitive with grid-connected solar PV in many other regions.
