The world requires genuine endeavors for gradual introduction of sustainable power sources to satisfy the future energy needs. Renewable energy (RE) of enormous capacity exists at various geological locations but suffers from intermittent nature. In such situations, one RE can complement other and improve the system’s efficiency. This is an example of valorization where hybridization improves the quality of a commodity. It has been found out that hybrid of two or more technologies, alongside storage can improve framework efficiency. The hybrid energy sources follows up on the idea of circular economy where the circular progression of resource–product–recycled​ resources is planned for decreasing both the utilization of raw materials and waste generation. It has been found that despite the fact that such projects are expensive at the beginning; in long term they prove to be advantageous. The paper discusses about the hybrids done so far and through case studies and economic analysis. It also suggests which hybrid arrangements can assist each other. The present study examines the major problems associated with hybrid renewable energy and identifies the solutions. The paper comes up with a novel low cost hybrid solution of solar and geothermal which is implemented in the geothermal plant in Gujarat, India. It is discussed that the concept of hybrid renewable energy when put into a circular economy model, would give solutions that are affordable, practical and provides societal benefits.

循环经济中混合可再生能源的整体评估以进行价值评估和管理

世界需要真正的努力,逐步引入可持续的能源,以满足未来的能源需求。巨大的可再生能源(RE)存在于不同的地质位置,但具有间歇性。在这种情况下,一个可再生能源可以补充其他资源并提高系统效率。这是增值的一个例子,其中杂交提高了商品的质量。已经发现,两种或多种技术的混合以及存储可以提高框架效率。混合能源遵循了循环经济的思想,在循环经济中计划对资源产品循环利用的资源进行循环发展,以减少原材料的利用和废物的产生。已经发现,尽管这样的项目在开始时就很昂贵;从长远来看,它们被证明是有利的。本文通过案例研究和经济分析,讨论了迄今为止的混合动力汽车。它还暗示了哪些混合动力安排可以互相帮助。本研究研究了与混合可再生能源有关的主要问题并确定了解决方案。该论文提出了一种新颖的低成本的太阳能和地热混合解决方案,该解决方案在印度古吉拉特邦的地热发电厂中实施。讨论了将混合可再生能源的概念纳入循环经济模型后,将提供价格合理,实用且可带来社会效益的解决方案。本研究研究了与混合可再生能源有关的主要问题并确定了解决方案。该论文提出了一种新颖的低成本的太阳能和地热混合解决方案,该解决方案在印度古吉拉特邦的地热发电厂中实施。讨论了将混合可再生能源的概念纳入循环经济模型后,将提供价格合理,实用且可带来社会效益的解决方案。本研究研究了与混合可再生能源有关的主要问题并确定了解决方案。该论文提出了一种新颖的低成本的太阳能和地热混合解决方案,该解决方案在印度古吉拉特邦的地热发电厂中实施。讨论了将混合可再生能源的概念纳入循环经济模型后,将提供价格合理,实用且可带来社会效益的解决方案。
