Relevance of New Materials for Energy Storage-Crimson Publishers




Today, perhaps electricity is the third most important commodity, next to only air and water. There is a continuous increase in demand for electricity. In fact the UN index for quality of life is per capita energy consumption. For a very long time electric power system is centrally controlled networks with generators located at the site of energy source and loads being large urban centers distant from power plants. Predominantly coal, oil, natural gas, and water have been energy sources from the beginning of electricity use. Among them, except water other three are fossil based fuels and are responsible for environmental pollution, necessitating locating power plants centrally and remotely. In view of dependence on the source and head of water, hydro generation is also centrally located. All this calls for transmission over long distances contributing to losses. Thus, there are low efficiencies in delivery, together with increased pollution and depletion of fossil fuels. This has brought developments in renewable energy sources based on solar and wind energy to the fore. Figures 1 & 2 show Global cumulative installed capacity of the wind and solar power in 2014 country wise, respectively [1,2].
