Microgrid Environmental Impact

2020 6th IEEE International Energy Conference (ENERGYCon), 2020
Les centrales électriques ont de mauvais impacts sur l'environnement. L'un de ces impacts est l'émission de dioxyde de carbone (CO2) résultant des centrales électriques qui dépendent des combustibles fossiles, du pétrole et du gaz naturel. L'énergie renouvelable est considérée comme une solution importante à ce problème car elle est classée comme une ...
