A Comparative Review on Renewable Energy Application, Difficulties and Future Prospect

According to the population growth, the energy demand has grown rapidly. Besides these, economic and technological improvement demands more energy utilization. But the world's treasured energies are limited. It is also important that more uses of conventional energy resources create a huge greenhouse gas which have an adverse effect on global ecosystem. But without energy, modernization of our civilization is quite impossible. So, to save our planet, we have to choose some alternative resources of energy. That alternative energy sources should be renewable and sustainable. In this world we can find different types of renewable energy in different geographical position. The main advantages of renewable energy are that, it has a little effect on ecosystem, it can be collected even in bad weather condition and overall it is a weapon to fight against environmental pollution. It has a great influence on economic growth, job creation and energy security. But there are some problems in storing of renewable energy. Scientists and investors are continuously trying to overcome this problem. Sometime, protest from common people during the installation of renewable energy set up, make the situation difficult. Employment opportunities and some facilities reduce the protest against the application of sustainable energy. Public education and awareness on renewable energy helps the policymaker to make decisions. From study of review papers about the renewable energy it is found that a massive experiment is going on sustainable energy. This paper has established an idea about different renewable energy application, their difficulties of application and their solution. It is also observed that with rising government strategy to reduce carbon emission for economic growth and with proper technique and storage arrangement, the renewable energy application will significantly expand in few years.
