one that results in improved human well-being and social equity, while significantly reducing environmental risks and ecological scarcities. In other words, we can think of a green economy as an economic environment that achieves low carbon emissions, resource efficiency and at the same time is socially inclusive.
Renewable Energy  is one of the key sectors of a green economy. In India, growing concerns about energy security  have led the government to commit to the development of renewable energy, with special focus on harnessing the abundantly available solar energy. In 2008, during the launch of India's National Action Plan on Climate Change, the Indian Prime Minister Dr. Manmohan Singh had stated:
Our vision is to make India’s economic development energy-efficient. Over a period of time, we must pioneer a graduated shift from economic activity based on fossil fuels to one based on non-fossil fuels and from reliance on non-renewable and depleting sources of energy to renewable sources of energy. In this strategy, the sun occupies centre-stage, as it should, being literally the original source of all energy. We will pool our scientific, technical and managerial talents, with sufficient financial resources, to develop solar energy as a source of abundant energy to power our economy and to transform the lives of our people.
In line with this aim, the Jawaharlal Nehru National Solar Mission , which was launched on the 11th January, 2010 by the Prime Minister, has set an ambitious target of deploying 20,000 MW of grid connected solar power by 2022. Given that high cost is a key challenge in implementing solar projects, the solar mission aims to “reduce cost of solar power generation in the country through (i) long term policy; (ii) large scale deployment goals; (iii) aggressive R&D; and (iv) domestic production of critical raw materials, components and products, as a result to achieve grid tariff parity by 2022″.
On 24th May 2012, the Union Minister of New & Renewable Energy Dr. Farooq Abdullah , while addressing the first meeting of the Solar Energy Industry Advisory Council (SEIAC)  in New Delhi, called upon  the industry leaders to invest in Solar Energy Projects in the country. He assured them of the full support of the Government in setting up solar projects based on both grid connected as well as off grid applications. At the same time, he asked industry leaders to respond favourably and positively to the incentives offered by the Government in this direction. The Minister said that India has a vast scope for developing solar energy applications as still many parts of rural India do not have access to grid connected electricity. He cited the example of high altitude places in Ladakh where solar energy has changed people’s lives.
Despite being a power surplus state, Gujarat made great advances in solar energy. Our state was the earliest to come up with a solar policy. Just a few months ago, Gujarat dedicated to the nation 600 MW solar power to the nation along with Asia’s largest solar park at Charanka. Today, Gujarat produces 2/3rd of the solar power in India.
One grassroot initiative that has been focusing on popularizing solar electrification in remote, rural areas since 1984, is the Barefoot College  of Tilonia, the brainchild of Sanjit ‘Bunker’ Roy . In this TED video , Mr. Roy talks bout the Barefoot methodology. The Barefoot College essentially “trains a few members of the community to be ‘Barefoot Solar Engineers’ (BSEs)”. These BSEs in turn install, repair and maintain solar lighting units within the community as well as train other community members. The video below tells the story  of the first women Barefoot Solar Engineers of Hyderabad in Andhra Pradesh, India.
Today, the Barefoot Solar Engineers are growing in numbers and can be found not only in India but in many countries around the world as can be seen on this map  – truly a global movement.
On this World Environment Day, India is renewing its solar energy pledge – to bring down costs, scale up solar infrastructure, train more solar evangelists and perhaps spark a solar revolution .
