Do renewable energy sources perfectly displace non-renewable energy sources? Evidence from Asia–Pacific economies

To What Extent Do Alternative Energy Sources Displace Coal and Oil in Electricity Generation? A Mean-Group Panel Analysis

“…Again, in contrast to much of the earlier displacement literature (e.g., [1,[3][4][5][6]), we find electricity-generation coal-and oil-displacement effects that are unitary for solar and wind, and that are significant but less than unitary for hydro. It would be useful for future research to focus on the policies that encourage this substitution of nonfossil fuels for fossil fuels in electricity generation.…”

“…Sikirica [4] determined that core nations-primarily the same countries considered here-would need 2.6 megawatts per capita of alternative fuel generation to displace one megawatt per capita of fossil fuel generation. Rather et al [5] found nearly identical results for a panel of seven (of the 20) Asia Pacific Economic Cooperation economies (for slightly different energy aggregations, i.e., renewable electricity displacing non-renewables). Considering 73 economies, Rather and Mahalik [6] estimated an even lower displacement coefficient, suggesting that six units of renewable energy are necessary to displace one unit of fossil fuel energy.…”

“…Electricity generation sources like nuclear, hydro, solar, wind, and geothermal are essentially carbon-free at the margins. Yet, empirical analyses on the displacement impact of low-and zero-carbon energy sources often have yielded disappointing results (e.g., [1][2][3][4][5][6]); other analyses have calculated only a modest displacement effect that was less than one-to-one/unitary (e.g., [7,8]). The current paper revisits this displacement question and finds a substantial and much larger impact than did those previous papers for nonfossil fuels-particularly solar and wind-in displacing coal and oil used in electricity generation.…”

“…The displacement literature comes in two flavors: (1) the dependent variable is in energy consumption terms (e.g., [1,[3][4][5][6] and the present paper), and (2) the dependent variable is in carbon emissions terms (e.g., [2,[7][8][9]). It is important to note that when displacement papers consider carbon emissions, the focus is necessarily on carbon emissions from electricity generation since these are the emissions that electricity from nuclear or renewable sources would displace.…”

A novel optimal identification of various solar PV cell parameters by using MRDT controller

“…From the literature review, the usage of non-renewable energy sources is decreasing drastically because their drawbacks are more atmospheric pollution, extreme greenhouse gas emissions, more catchment area needed for developing the power plants, plus the input fuel transportation is also very high 1 . So, the researchers working on the development of renewable energy systems.…”
