Trends in Renewable Electricity Generation in the G20 Countries: An Analysis of the 1990–2020 Period

The use of electricity from non-renewable sources increases environmental impacts. Therefore, several countries have committed to increase the renewable sources. Considering importance Group Twenty (G20), this article aims identify trends in supply these countries. data collected are International Energy Agency (IEA) between 1990 and 2020. methods measured production each type G20 matrices identified influence population, Gross Domestic Product (GDP), CO2 emissions using multiple linear regression. In terms results, Brazil Canada most higher per capita than non-renewable. Saudi Arabia presented smallest matrix throughout analyzed period. All 20 varied electrical production, with different amounts solar, wind, hydro, biomass, geothermal, tidal energy. Countries highest GDP not necessarily largest producers electricity. Hydroelectric energy, biggest highlight is making room for other such as wind which grew participation matrices. waste, energy shown a timid but constant growth.
