Presentation Description

India accounts for about one-sixth (16% ) of the world’s population but only about 5% of the world’s primary energy consumption . A large proportion of India does not have access to electricity or convenient clean cooking fuels. In this talk I will present an overview of India’s present energy supply system and the availability of domestic fossil fuel reserves. In the context of the global problem of climate change and non-availability of domestic fossil fuels, future energy systems in India will need to increasingly rely on energy efficiency, renewables or nuclear. I will provide a status and trends of these options in India. I will highlight the challenges for the energy sector in India to provide access to energy in a sustainable fashion. Examples of distributed and centralized renewable based power in India will be used to illustrate some of the issues involved.
