Global warming are the most important problems in today’s world. The use of renewable energy increased greatly just after the first big oil crisis in the late seventies. At that time economic issues were the most important factors hence interest in such processes decreased when oil prices fell. The current resurgence of interest in the use of renewable energy is driven by the need to reduce the high environmental impact of fossil-based energy systems. Harvesting energy on a large scale is undoubtedly one of the main challenges of our time. Future energy sustainability depends heavily on how the renewable energy problem is addressed in the next few decades.
