Non-conventional energy – Need and scope in global and Indian scenario

Twentieth century saw the rapid spread of conventional energy usage worldwide, which brought life changing progress and improvement in quality of life. However, this progress came with a price, global warming and attended risks of climate change, loss of habitat and rise in sea level. The need of the hour is to reduce the rate of global warming. In this article, I have briefly described the history and use of conventional energy sources and the way we can introduce new nonconventional energy sources. Nonconventional energy is expensive now, because the technology is still in research and development phase. Even though the initial cost is high, it is expected to come down because newer technologies with lower costs will be developed with wide spread use.
