Review of current status of fossil fuel, renewable energy and storage devices: Context Bangladesh

This article highlights the current status of various energy sources both non-renewable and renewable and various storage devices that are in market practice in Bangladesh. The country, the eight most populated one in Asia has an installed electricity generation capacity of 20,000 MW. On an average only 77.9% of the population has access to electricity. The upliftment of the socio economic status of people leads to the growing demand for power. The power demand will be more than 30,000 MW by 2030. The depletion of fossil fuel leads to rethink the use of renewable sources of energy. The increased demand of power is overcome by the proper utilization of solar energy in recent years from 2017 to 2018 by having the maximum generation of 200 MW. Unlike regular storage devices in the conventional system, the ever-increasing power demand has led to increase in the utilization of the storage devices especially the battery. Usage of electromagnetic and mechanical storage systems will reduce the amount of carbon and toxic metals like lead, sulphur, etc. released to the atmosphere. Bangladesh has an estimated target of meeting its 50% power demand in 2030 by only using renewable sources and non-polluting storage systems. Moreover, the article gives lot of research focus to the market researchers with various advanced storage techniques discussed in one place. The availability of energy sources, power demand, and storage options clearly indicate that the sustainable development depends on energy conservation rather than energy utilization.
