Synopsis The concept of sustainable development may simply be comprehended to be refined version of development. Being abundantly available perennial and environmentally safe, the non-conventional energy resources have the potential to set forth a sustainable and equitable socio-economic development in the country. Renewable energy is seen as an effective option for ensuring access to modern energy services in our vast country. In addition, it also provides a degree of national energy security. In recent years, the rationale has been further buttressed by the environmental imperative. Decentralized renewable energy technologies can provide higher quality of cooking and lighting energy services to rural households. They are technologically and economically appropriate to meet low and dispersed rural energy demands. These are cleaner at the household, regional air quality and global climate change. The energy crisis has focused on the urgent need for deployment of non-conventional energy needs. Keeping in view the significance of renewable energy sources for sustainable development, the book consists of chapters on the utilization of renewable energy for domestic purposes, power generation, industrial uses and for energy saving houses. Various aspects of energy and different types of renewable energy technologies such as solar, thermal, solar photovoltaic, biomass energy, bio-gas technology, wind energy, geothermal energy, ocean energy have been discussed. Efforts have been made to provide the relevant latest information available in the field of renewable energy technologies and their utilization for sustainable development. This work is multi-dimensional in approach and is likely to prove useful for engineers, research scientists and students engaged in the field of renewable energy.
