The rest of the sentences are numbered as B, C, D, ad E, which are not in proper order. Read the sentences and place them in chronological order. National Solar Mission is one of the eight missions set up of National Action Plan on Climate change (NAPCC) that was released on 30 June 2008. With this ambitious target, India will become one of the largest Green Energy producers in the world, surpassing several developed countries. Government stepped up India’s solar power capacity target under the Jawaharlal Nehru National Solar Mission (JNNSM), by five times, reaching 1,00,000 MW by 2022. The target will principally comprise 40 GW Rooftop and 60 GW through Large and Medium Scale Grid Connected Solar Power Projects. The new targets were approved in June 2015. During recent times with improvement in technology and scaling up production capacities, solar energy has become cost-competitive and targets seem to be more viable now.
