Renewable Energy
Introduction
Experts and policy makers are unanimous that increasing use of renewable energy sources is the only long term solution to balance the developmental as well as environmental challenges. However, high capital costs negatively affect the growth in size of total investment in renewable energy technologies, the parity concerns in comparison to fossil-fuel based power make it unattractive to consumers, huge financial requirements on supply side as well as on demand side make them economically not so feasible an option in short term, and the infrastructure development needs for building complete supply chain for renewable energy sector entail even higher financial resource requirements. Countries have been making efforts to address these challenges, primarily from energy security point of view. Various incentives and initiatives have been attempted in different countries with mixed experience. In summary, there is still a long way to go to have renewable energy penetration at an adequate level.
