Contribution of renewable energy to human life is essential for sustainable life on Earth. The renewable energy industry is growing rapidly to fulfil the energy demand of the continuously developing world and has become the focal centre of many researchers across the globe. This development should meet the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development ties together concerns for the carrying capacity of natural systems with the social challenges faced by humanity. This book is intended to highlight various aspects for applications of renewable energy and sustainability. This work is a collaborative attempt to elaborate useful technical information from many countries across the globe about the competent and effective use of renewable energy systems. This book presents theoretical and experimental analysis, case studies and models in renewable energy systems issues related to Solar Energy, Wind Energy, Bio Energy, Tidal Energy, Geothermal Energy, Fuel Cells, and Energy Storage Systems. This book also contains different considerations in order to develop products contributing to the sustainability of life.

In the present investigation, information has been collected on about 63 plants used for medicinal purposes of Irulas and MudugasTribes. Based on the information gathered, nine plants viz., Pelargonium, graveolens, Ocimum basilicum, Cympopogan citratus, Eucalyptus globulus, Ruta chalepensis, Premna corymbosa, Plactranthus amboinicus, Placanthus barbatus and Scoparia dulcis were selected and their ethanolic extraction of the leaves were made by Soxlet apparatus. Essential volatile oils were obtained from the leaves by steam distillation. Mosquito repellent formulation like coil, skin lotion, mat and liquidizer was done by using plants products in combination with inert substances. And the efficiency of repellent products were tested against vector mosquitoes, Anopheles stephensi, Liston, Culex quinquefasciatus Say, Aedes aegypti (Linn.), Smoke repellent activity, skin repellent activity, the maximum Liquid Mosquito Insecticide Extract Formulation (LMIEF), vapourising mats were carried out against vector mosquitoes. Among the nine plants tested Pelargonium, graveolens was foud to be more effective in the smoke repellent, skin repellent activity against three vector mosquitoes tested.
