Abstract: With increase in population and advent of electric vehicles, electricity consumption in world will comprise an increasing portion of global energy demand in upcoming decades. In recent years, the increasing prices of fossil fuels and concerns about the environmental consequences of greenhouse gas emissions have renewed the interest in the development of alternative energy resources. Utilization of solid wastes as a renewable source of energy can achieve sustainable development and overcome shortage of other energy sources. We are highlighting the various routes of harvesting energy from solid waste into clean and sustainable way. Waste to energy concepts are techniques to address the growing menace of solid waste as well as to meet upcoming demands of energy in the form of biofuels. This concept provides environmental benefits and introduce a renewable energy source as well. Here, we discuss alternative technologies for enhancing renewable energy deployment and energy use efficiency from solid waste and also focuses the renewable energy scenario of India.
